CSS 背景位置 background-position属性

发表评论

除了背景背景平铺外，CSS还提供了另一个强大的功能，即背景定位技术，能够精确控制背景在对象中的位置。

默认情况下，背景图像都是从元素 padding 区域的左上角开始出现的，但设计师往往希望背景能够出现在任何位置。通过 background-position属性，可以很轻松的控制背景图像在对象的背景区域中的起始显示位置。其语法格式为：

background-position: xpos ypos | x% y% | x y

CSS1中，background-position属性需要 2 个参数值，第一个值用于横坐标，第二个值用于纵坐标，默认值为 0% 0%，即背景图像的左上角与对象背景区域的左上角对齐。如果只提供一个值，则用于 x 轴方向，y 轴方向使用默认值 center，即垂直居中。

上述语法格式表明，背景图像有 3 种定位方式：

1）xpos ypos：表示使用预定义关键字定位，水平方向可选关键字有 left | center | right，垂直方向可选关键字有 top | center | bottom。

关键字定位，应用的是对齐规则，而不是坐标规则。xpos 为 left 表示图像的左边与对象的左边对齐，为 right 表示图像的右边和对象的右边对齐；ypos 为 top 表示图像的顶部和对象的顶部对齐，为 bottom 表示图像的底部和对象的底部对齐；xpos、ypos等于 center表示图像在水平和垂直方向的中心，和对象在水平和垂直方向的中心对齐，即。

依然使用前面的背景图案 bg.gif，其尺寸为 100px * 100px，对象的尺寸为 200px * 200px，背景图像的位置使用预定义关键字定位。如：

div {
width: 200px;
height: 200px;
border: 1px dashed #ccc;
background-repeat: no-repeat;
background-position: center center;
background-image: url(img/bg.gif);
}

上述定位，就表示背景图像的中心，与背景区域的中心对齐，即背景图像位于对象的中央位置。运行结果如图 4‑28 所示：

图4-28 背景图像关键字定位

2）x% y%：表示使用百分比定位，是将图像本身（x%, y%）的那个点，与背景区域的（x%, y%）的那个点重合。最终得到背景图像起始位置坐标的计算公式为：

x = (对象的宽度 – 图像的宽度) * x%;

y = (对象的高度 – 图像的高度) * y%;

还是上面的例子，改为百分比定位，要使背景图像居中，只需把背景图像的位置设置为50% 50% 即可。使用上面的公式，得到背景图像起始位置的坐标为：

x：(200px – 100px) * 50% = 100px * 50% = 50px

y：(200px – 100px) * 50% = 100px * 50% = 50px

得到的结果与上例相同，限于篇幅，就不再截图了。当然，百分比的值也可以是负值，计算公式依然不变。还是上面的例子，把百分比改为 -50% -50%。此时，得到背景图像起始位置的坐标为：

x：(200px – 100px) * (-50%) = 100px * (-50%) = -50px

y：(200px – 100px) * (-50%) = 100px * (-50%) = -50px

运行结果如图 4‑29 所示：

图4-29 背景图像百分比定位

从上图可以看出，此时的背景图像只显示了原本图像的 1/4，这是因为背景图像的起始位置向左、向上移动后，只有1/4 的图案落到了背景区域。由于背景被设置为不重复，所以，就只显示了原本图像的 1/4。

3）x y：表示使用长度值定位，是将背景图像的左上角，放置在对象的背景区域中（x, y）所指定的位置，即 x, y 定义的是背景图像的左上角，相对于背景区域左上角的偏移量。

偏移量长度可以是正值，也可以是负值。x 为正值表示向右偏移，负值表示向左偏移；y 为正值表示向下偏移，负值表示向上偏移。背景图像发生移动后，就有可能超出对象的背景区域。此时，超出的部分将不会显示，只会显示落入背景区域的部分。

如果把上面的例子改为长度值定位，要使背景图像居中，只需把背景图像的位置设置为50px 50px 即可。它就表示背景图像的左上角顶点，相对于对象背景区域的左上角顶点在 x轴右移 50px，在 y 轴下移 50px。得到的结果依然是背景图像位于对象的中央。

在CSS3中，background-position属性支持 4 个参数值，前两个值用于横坐标，后两个值用于纵坐标。这意味着我们可以相对于上左下右任意一个角落定位，而不是之前只能相对于左上角定位。可以用长度值、或百分比来指定背景图像的起始位置。

如果只提供一个值，则第二个值为center。如果提供两个值，第一个长度或百分比表示水平偏移，第二个长度或百分比表示垂直偏移。长度或百分比，表示背景图像的左上角相对于背景位置区域左上角的偏移。如，下面几个声明给出了背景的起点相对于背景区域左上角的偏移：

background-position: left 10px top 15px; /* 10px, 15px */
background-position: left top ; /* 0px, 0px */
background-position: 10px 15px; /* 10px, 15px */
background-position: left 15px; /* 0px, 15px */
background-position: 10px top ; /* 10px, 0px */
background-position: left top 15px; /* 0px, 15px */
background-position: left 10px top ; /* 10px, 0px */

CSS实现垂直居中的几种方法

发表评论

======

正文回到顶部

单行文本的居中

1.文字水平居中

1 <div class='box' style="text-align: center;">hello world</div>

2.文本垂直水平居中

1 <div class="box2" style="width:150px;height:100px;line-height: 100px;">文本垂直水平居中</div>

回到顶部

二、多行文本的垂直居中

1.使用display:flex实现

flex布局会让容器内的元素得到垂直水平居中

 1 <!DOCTYPE html>
 2 <html>
 3 <head>
 4     <meta charset="utf-8">
 5     <title>登陆</title>
 6     <style type="text/css">
 7         html{width: 100%;height: 100%;}  /*整个页面的居中*/
 8         body{
 9             width: 100%;
10             height: 100%;
11             display: flex;             /*flex弹性布局*/
12             justify-content: center;
13             align-items: center;
14         }
15         #login{
16             width: 300px;
17             height: 300px;
18             border: 1px black solid; 
19             display: flex;
20             flex-direction: column;        /*元素的排列方向为垂直*/
21             justify-content: center;    /*水平居中对齐*/
22             align-items: center;        /*垂直居中对齐*/
23         }
24     </style>
25 </head>
26 <body>
27     <div id="login">
28         <h1>登陆</h1>
29         <input type="text"><br>
30         <input type="password"><br>
31         <button>确定</button>
32     </div>
33 </body>
34 </html>

2.使用display:-webkit-box实现

1         body{
2             width: 100%;
3             height: 100%;
4             display: -webkit-box;             /*flex弹性布局*/
5             -webkit-box-align: center;
6             -webkit-box-pack: center;
7         }

display:flex和display:box都可用于弹性布局实现水平垂直居中，不同的是display:box是2009年的命名，已经过时，用的时候需要加上前缀；display:flex是2012年之后的命名

3.使用绝对定位和负边距

　　CSS代码：

<style>
        .box{
               width: 150px;
               height: 150px;
               background:blue;
               position: relative;
        }
        p{
               width: 50px;
               height: 50px;
               background:red;
               position: absolute;
               left:50%;
               top:50%;
               margin-left:-25px;
               margin-top: -25px;
               display: flex;
               align-items: center;
               justify-content: center;
        }
    </style>

　　HTML代码：

1     <div class="box"><p>A</p></div>

4.使用transform:translate定位

 1     <style>
 2     *{padding: 0;margin: 0;}   /*解决容器内元素.div是p元素产生的居中不完整*/
 3         .box{
 4                 margin: 20px auto;
 5                 width: 150px;height: 150px;
 6                 background:blue;
 7                 position: relative;
 8                 text-align: center;
 9         }
10         .box .div1{    
11             position: absolute;
12             top:50%;
13             left:50%;
14             width:100%;
15             transform:translate(-50%,-50%);
16             text-align: center;
17             background: red
18         }
19     </style>

说明：/*一般情况下子元素不能是p元素，否则非完全居中，P元素自带有padding距离*/，.div1如果必须是p元素则必须加上*{margin:0;padding:0;};进行初始化，

5.绝对定位和0

 1         .box p{    
 2             width:50%;
 3             height: 50%;
 4             overflow: auto;
 5             position: absolute;
 6             background:red;
 7             margin: auto;
 8             top:0;
 9             bottom:0;
10             left:0;
11             right:0;
12         }

6.通过display:table-cell

1         .box{
2                 width: 150px;height: 150px;
3                 background:blue;
4                 position: relative;
5                 text-align: center;
6                 display: table-cell;
7                 vertical-align: middle;
8 }

缺点：对容器.box的子元素的设置宽高会造成失效。

HTML+CSS+JS dTree 树形目录的使用

发表评论

example 压缩包：https://pan.baidu.com/s/1DI2mM3iSnKtpkV45-gUzAA 提取码: m1pi

使用注意事项：

1）dtree.js里可以修改点击项目的操作

原js文件里的nodeSel和node的样式切换不生效，可以在点击方法里添加

var cur_sel_id = -1;
function setDetail(api_id, name){
    console.log(api_id);
    if(cur_sel_id >= 0){
        var old = document.getElementById("sd"+ cur_sel_id);
        old.className = "node";
    }
    eNew = document.getElementById("sd"+ api_id);
    eNew.className = "nodeSel";
    …………
}

使用 CSS 渐变

发表评论

CSS 渐变 <image> 类型的一种特殊类型 <gradient> 表示，由两种或多种颜色之间的渐进过渡组成。您可以选择三种类型的渐变：线性 (由 linear-gradient 函数创建)，径向(由 radial-gradient() 函数创建) 和圆锥 (由 conic-gradient 函数创建)。您还可以使用 repeating-linear-gradient 和 repeating-radial-gradient 函数创建重复渐变。

渐变可以在任何使用 <image> 的地方使用，例如在背景中。由于渐变是动态生成的，因此它们可以消除对传统用于实现类似效果的栅格图像文件的需求。此外，由于渐变是由浏览器生成的，因此在放大时它们看起来比栅格图像更好，并且可以动态调整大小。

我们将从线性渐变开始介绍，然后以线性渐变为例介绍所有渐变类型支持的功能，然后继续介绍径向渐变，圆锥渐变和重复渐变。

使用线性渐变

线性渐变创建了一条沿直线前进的颜色带。

基础线性渐变

要创建最基本的渐变类型，您只需指定两种颜色即可。这些被称为色标。至少指定两个色标，也可以指定任意数量。

.simple-linear {
  background: linear-gradient(blue, pink);
}

改变渐变方向

默认情况下，线性渐变的方向是从上到下，你可以指定一个值来改变渐变的方向。

.horizontal-gradient {
  background: linear-gradient(to right, blue, pink);
}

对角线渐变

你甚至可以设置渐变方向为从一个对角到另一个对角。

.diagonal-gradient {
  background: linear-gradient(to bottom right, blue, pink);
}

设置渐变角度

如果你想要更精确地控制渐变的方向，你可以给渐变设置一个具体的角度。

.angled-gradient {
  background: linear-gradient(70deg, blue, pink);
}

在使用角度的时候, 0deg 代表渐变方向为从下到上, 90deg 代表渐变方向为从左到右，诸如此类正角度都属于顺时针方向。而负角度意味着逆时针方向。

声明颜色和创建效果

所有的CSS渐变类型都是一个位置依赖的颜色范围。CSS渐变产生的颜色可以随位置不断变化，从而产生平滑的颜色过渡。也可以创建纯色带和两种颜色之间的硬过渡。以下内容适用于所有渐变函数：

使用多种颜色

无需局限于使用两种颜色，你想使用多少种颜色都可以！默认情况下，所设置颜色会均匀分布在渐变路径中。

.auto-spaced-linear-gradient {
  background: linear-gradient(red, yellow, blue, orange);
}

颜色终止位置

你不需要让你设置的颜色在默认位置终止。你可以通过给每个颜色设置0，1%或者2%或者其他的绝对数值来调整它们的位置。如果你将位置设置为百分数， 0% 表示起始点, 而100%表示终点，但是如果需要的话你也可以设置这个范围之外的其他值来达到你想要的效果。如果有些位置你没有明确设置，那么它将会被自动计算，第一种颜色会在0%处停止，而最后一种颜色是100%，至于其他颜色则是在它邻近的两种颜色的中间停止。

.multicolor-linear { 
   background: linear-gradient(to left, lime 28px, red 77%, cyan);
}

创建实线

要在两种颜色之间创建一条硬线，即创建一个条纹而不是逐渐过渡，可以将相邻的颜色停止设置为相同的位置。在此示例中，两种颜色在50%标记处共享一个颜色停止点，即渐变的一半：

.striped { 
   background: linear-gradient(to bottom left, cyan 50%, palegoldenrod 50%); 
}

渐变提示

默认情况下，渐变会平滑地从一种颜色过渡到另一种颜色。你可以通过设置一个值来将渐变的中心点移动到指定位置。在如下示例中, 我们将渐变的中心点由50%设为10%。

.color-hint {
  background: linear-gradient(blue, 10%, pink);
}
.simple-linear {
  background: linear-gradient(blue, pink);
}

创建色带和条纹

要在渐变中包含一个实心的非过渡颜色区域，请包含颜色起止点的两个位置。颜色起止点可以有两个位置，这相当于两个连续颜色在不同位置具有相同的颜色起止点。颜色将在第一个颜色起止点时达到完全饱和，保持该饱和度到第二个颜色起止点，并通过相邻颜色起止点的第一个位置过渡到相邻颜色起止点的颜色。

.multiposition-stops { 
   background: linear-gradient(to left, 
       lime 20%, red 30%, red 45%, cyan 55%, cyan 70%, yellow 80% );  
   background: linear-gradient(to left, 
       lime 20%, red 30% 45%, cyan 55% 70%, yellow 80% ); 
}
.multiposition-stop2 { 
   background: linear-gradient(to left, 
      lime 25%, red 25%, red 50%, cyan 50%, cyan 75%, yellow 75% ); 
   background: linear-gradient(to left, 
      lime 25%, red 25% 50%, cyan 50% 75%, yellow 75% ); 
}

In the first example above, the lime goes from the 0% mark, which is implied, to the 20% mark, transitions from lime to red over the next 10% of the width of the gradient, reach solid red at the 30% mark, and staying solid red up until 45% through the gradient, where it fades to cyan, being fully cyan for 15% of the gradient, and so on.

In the second example, the second color stop for each color is at the same location as the first color stop for the adjacent color, creating a striped effect.

In both examples, the gradient is written twice: the first is the CSS Images Level 3 method of repeating the color for each stop and the second example is the CSS Images Level 4 multiple color stop method of including two color-stop-lengths in a linear-color-stop declaration.

Controlling the progression of a gradient

By default, a gradient evenly progresses between the colors of two adjacent color stops, with the midpoint between those two color stops being the midpoint color value. You can control the interpolation, or progression, between two color stops by including a color hint location. In this example, the color reaches the midpoint between lime and cyan 20% of the way through the gradient rather than 50% of the way through. The second example does not contain the hint to hilight the difference the color hint can make:

.colorhint-gradient {
  background: linear-gradient(to top, black, 20%, cyan);
}
.regular-progression { 
  background: linear-gradient(to top, black, cyan);
}

Overlaying gradients

Gradients support transparency, so you can stack multiple backgrounds to achieve some pretty fancy effects. The backgrounds are stacked from top to bottom, with the first specified being on top.

.layered-image {
  background: linear-gradient(to right, transparent, mistyrose),
      url("https://mdn.mozillademos.org/files/15525/critters.png");
}

Stacked gradients

You can even stack gradients with other gradients. As long as the top gradients aren’t entirely opaque, the gradients below will still be visible.

.stacked-linear {
  background:
      linear-gradient(217deg, rgba(255,0,0,.8), rgba(255,0,0,0) 70.71%),
      linear-gradient(127deg, rgba(0,255,0,.8), rgba(0,255,0,0) 70.71%),
      linear-gradient(336deg, rgba(0,0,255,.8), rgba(0,0,255,0) 70.71%);
}

Using radial gradients

Radial gradients are similar to linear gradients, except that they radiate out from a central point. You can dictate where that central point is. You can also make them circular or elliptical.

A basic radial gradient

As with linear gradients, all you need to create a radial gradient are two colors. By default, the center of the gradient is at the 50% 50% mark, and the gradient is elliptical matching the aspect ratio of it’s box:

.simple-radial {
  background: radial-gradient(red, blue);
}

Positioning radial color stops

Again like linear gradients, you can position each radial color stop with a percentage or absolute length.

.radial-gradient {
  background: radial-gradient(red 10px, yellow 30%, #1e90ff 50%);
}

Positioning the center of the gradient

You can position the center of the gradient with keyterms, percentage, or absolute lengths, length and percentage values repeating if only one is present, otherwise in the order of position from the left and position from the top.

.radial-gradient {
  background: radial-gradient(at 0% 30%, red 10px, yellow 30%, #1e90ff 50%);
}

Sizing radial gradients

Unlike linear gradients, you can specify the size of radial gradients. Possible values include closest-corner, closest-side, farthest-corner, and farthest-side, with farthest-corner being the default.

Example: closest-side for ellipses

This example uses the closest-side size value, which means the size is set by the distance from the starting point (the center) to the closest side of the enclosing box.

.radial-ellipse-side {
  background: radial-gradient(ellipse closest-side,
      red, yellow 10%, #1e90ff 50%, beige);
}

Example: farthest-corner for ellipses

This example is similar to the previous one, except that its size is specified as farthest-corner, which sets the size of the gradient by the distance from the starting point to the farthest corner of the enclosing box from the starting point.

.radial-ellipse-far {
  background: radial-gradient(ellipse farthest-corner at 90% 90%,
      red, yellow 10%, #1e90ff 50%, beige);
}

Example: closest-side for circles

This example uses closest-side, which makes the circle’s size to be the distance between the starting point (the center) and the closest side. The circle’s radius is the distance between the center of the gradient and the closest edge, which due to the positioning of the 25% from the top and 25% from the bottom, is closest to the bottom, since the height in this case is narrower than the width.

.radial-circle-close {
  background: radial-gradient(circle closest-side at 25% 75%,
      red, yellow 10%, #1e90ff 50%, beige);
}

Stacked radial gradients

Just like linear gradients, you can also stack radial gradients. The first specified is on top, the last on the bottom.

.stacked-radial {
  background: 
      radial-gradient(circle at 50% 0,
        rgba(255,0,0,.5),
        rgba(255,0,0,0) 70.71%),
      radial-gradient(circle at 6.7% 75%,
        rgba(0,0,255,.5),
        rgba(0,0,255,0) 70.71%),
      radial-gradient(circle at 93.3% 75%,
        rgba(0,255,0,.5),
        rgba(0,255,0,0) 70.71%) beige;
  border-radius: 50%;
}

Using repeating gradients

The linear-gradient and radial-gradient() properties don’t support automatically repeated color stops. However, the repeating-linear-gradient and repeating-radial-gradient properties are available to offer this functionality.

The size of the gradient line that repeats is the length between the first color stop value and the last color stop length value. If the last color stop has just a color and no color stop length, the value defaults to 0, meaning the linear gradient will not repeat and the radial gradient will only repeat if the radius of the gradient is smaller than the length between the center of the gradient and the farthest corner.

Repeating linear gradients

This example uses repeating-linear-gradient to create a gradient that progresses repeatedly in a straight line. The colors get cycled over again as the gradient repeats. In this case the gradient line is 10px long.

.repeating-linear {
  background: repeating-linear-gradient(-45deg, red, red 5px, blue 5px, blue 10px);
}

Multiple repeating linear gradients

Similar to regular linear and radial gradients, you can include multiple gradients, one on top of the other. This only makes sense if the gradients are partially transparent allowing subsequent gradients to show through the transparent areas, or if you include different background-sizes, optionally with different background-position property values, for each gradient image. We are using transparency.

In this case the gradient lines are 300px, 230px, and 300px long.

.multi-repeating-linear {
  background:
      repeating-linear-gradient(190deg, rgba(255, 0, 0, 0.5) 40px,
        rgba(255, 153, 0, 0.5) 80px, rgba(255, 255, 0, 0.5) 120px,
        rgba(0, 255, 0, 0.5) 160px, rgba(0, 0, 255, 0.5) 200px,
        rgba(75, 0, 130, 0.5) 240px, rgba(238, 130, 238, 0.5) 280px,
        rgba(255, 0, 0, 0.5) 300px),
      repeating-linear-gradient(-190deg, rgba(255, 0, 0, 0.5) 30px,
        rgba(255, 153, 0, 0.5) 60px, rgba(255, 255, 0, 0.5) 90px,
        rgba(0, 255, 0, 0.5) 120px, rgba(0, 0, 255, 0.5) 150px,
        rgba(75, 0, 130, 0.5) 180px, rgba(238, 130, 238, 0.5) 210px,
        rgba(255, 0, 0, 0.5) 230px),
      repeating-linear-gradient(23deg, red 50px, orange 100px,
        yellow 150px, green 200px, blue 250px,
        indigo 300px, violet 350px, red 370px);
}

Plaid gradient

To create plaid we include several overlapping gradients with transparency. In the first background declaration we listed every color stop separately. The second background property declaration using the multiple position color stop syntax:

.plaid-gradient {
  background:
      repeating-linear-gradient(90deg, transparent, transparent 50px,
        rgba(255, 127, 0, 0.25) 50px, rgba(255, 127, 0, 0.25) 56px,
        transparent 56px, transparent 63px,
        rgba(255, 127, 0, 0.25) 63px, rgba(255, 127, 0, 0.25) 69px,
        transparent 69px, transparent 116px,
        rgba(255, 206, 0, 0.25) 116px, rgba(255, 206, 0, 0.25) 166px),
      repeating-linear-gradient(0deg, transparent, transparent 50px,
        rgba(255, 127, 0, 0.25) 50px, rgba(255, 127, 0, 0.25) 56px,
        transparent 56px, transparent 63px,
        rgba(255, 127, 0, 0.25) 63px, rgba(255, 127, 0, 0.25) 69px,
        transparent 69px, transparent 116px,
        rgba(255, 206, 0, 0.25) 116px, rgba(255, 206, 0, 0.25) 166px),
      repeating-linear-gradient(-45deg, transparent, transparent 5px,
        rgba(143, 77, 63, 0.25) 5px, rgba(143, 77, 63, 0.25) 10px),
      repeating-linear-gradient(45deg, transparent, transparent 5px,
        rgba(143, 77, 63, 0.25) 5px, rgba(143, 77, 63, 0.25) 10px);

  background:
      repeating-linear-gradient(90deg, transparent 0 50px,
        rgba(255, 127, 0, 0.25) 50px 56px,
        transparent 56px 63px,
        rgba(255, 127, 0, 0.25) 63px 69px,
        transparent 69px 116px,
        rgba(255, 206, 0, 0.25) 116px 166px),
      repeating-linear-gradient(0deg, transparent 0 50px,

Repeating radial gradients

This example uses repeating-radial-gradient to create a gradient that radiates repeatedly from a central point. The colors get cycled over and over as the gradient repeats.

.repeating-radial {
  background: repeating-radial-gradient(black, black 5px, white 5px, white 10px);
}

Multiple repeating radial gradients

.multi-target {
  background:
      repeating-radial-gradient(ellipse at 80% 50%,rgba(0,0,0,0.5),
        rgba(0,0,0,0.5) 15px, rgba(255,255,255,0.5) 15px,
        rgba(255,255,255,0.5) 30px) top left no-repeat, 
      repeating-radial-gradient(ellipse at 20% 50%,rgba(0,0,0,0.5),
        rgba(0,0,0,0.5) 10px, rgba(255,255,255,0.5) 10px,
        rgba(255,255,255,0.5) 20px) top left no-repeat yellow;
  background-size: 200px 200px, 150px 150px;
}

Plaid gradient

<div class="plaid-gradient"></div>

div {
  width: 200px;
  height: 200px;
}

.plaid-gradient {
  background:
      repeating-linear-gradient(90deg, transparent, transparent 50px,

CSS—display详解

发表评论

inline

　　常用的inline就是文字和图片，其实inline真没什么好说的，大家可以把它想象成一个杯子里的水，它是“流”，是没有大小和形状的，它的宽度取决于父容器的宽度。

　　因此，针对inline的标签，你设置宽度和高度是无效的，通过监控可以知道，该元素实际的宽度和高度都是auto，并不是我们设定的值。

　　一个很基础的问题：如何把inline元素转换成“块”元素？相信绝大部分人的回答是display:block，但是你应该知道这不是一个唯一的答案。至少我设置display:table也是可以的吧？

还有两种情况你应该去了解（如果你不知道的话）：

第一，对inline元素设置float

还是刚才那个例子，我们对span元素添加一个float:left，运行看看效果，你就会大吃一惊。从显示的效果和监控的结果上看来，span元素已经“块”化。注意，上一节刚刚讲完float，不要忘记float的“破坏性”、“包裹性”，在这里同样适用。

第二，对inline元素设置position:absolute/fixed

还是有同一个例子做演示，这次在span元素上加上absolute/fixed，效果大家应该能猜到，和加上float的效果相同。至于absolute/fixed有什么特性，会在下一节介绍position时提到。

3. block

　　本系列有一节重点讲解了《盒子模型》，不知道大家看没看过，或者说你已经很了解盒子模型了。

　　其实对于block，我觉得就是“盒子模型”。一个元素设置了block，它就必须遵循盒子模型的规则。因此，这里也不再去详细写它了，大家可以去盒子模型那一节好好看看，就那么点内容。

4. inline-block

　　这个话题还得从《浏览器默认样式》这一节开始。浏览器默认样式中规定了几个html元素为display:inline-block，回顾一下。

　　初学者对于inline-block可能比较陌生，没关系，一步一步来。首先，你应该知道inline是什么样子的，就是一般的文字、图片；其次，你应该知道block是什么样子的，一般的div就是；最后，inline-block顾名思义，它既有inline的特性，又有block的特性，大家可以想想一般的button、input是什么样子的。

　　那button举例子。我们在页面中输入若干个<button>，发现它们是“流”式排列的（可以对比一下若干个<div>的排列方式）。但是针对一个button，我们还可以自定义修改它的形状，这样就有“块”的特征。

　　因此，inline-block的特点可以总结为：外部看来是“流”，但是自身确实一个“块”。不知道大家理解也无？

1.解释一下display的几个常用的属性值，inline ， block， inline-block

inline:
1. 使元素变成行内元素，拥有行内元素的特性，即可以与其他行内元素共享一行，不会独占一行.
2. 不能更改元素的height，width的值，大小由内容撑开.
3. 可以使用padding，margin的left和right产生边距效果，但是top和bottom就不行.
block:
1. 使元素变成块级元素，独占一行，在不设置自己的宽度的情况下，块级元素会默认填满父级元素的宽度.
2. 能够改变元素的height，width的值.
3. 可以设置padding，margin的各个属性值，top，left，bottom，right都能够产生边距效果.
inline-block:
1. 结合了inline与block的一些特点，结合了上述inline的第1个特点和block的第2,3个特点.
2. 用通俗的话讲，就是不独占一行的块级元素。如图:

图一:

图二：

两个图可以看出，display：inline-block后块级元素能够在同一行显示，有人这说不就像浮动一样吗。没错，display：inline-block的效果几乎和浮动一样，但也有不同，接下来讲一下inline-block和浮动的比较。

2.inline-block布局 vs 浮动布局

a.不同之处：对元素设置display：inline-block ，元素不会脱离文本流，而float就会使得元素脱离文本流，且还有父元素高度坍塌的效果

b.相同之处：能在某程度上达到一样的效果

　　我们先来看看这两种布局：
图一：display：inline-block

图二：对两个孩子使用float：left，我在上一篇浮动布局讲过，这是父元素会高度坍塌，所以要闭合浮动，对box使用overflow：hidden，效果如下：

>>乍一看两个都能做到几乎相同的效果，（仔细看看display：inline-block中有间隙问题，这个留到下面再讲）

　　c.浮动布局不太好的地方：参差不齐的现象，我们看一个效果：
图三：

图四：

>>从图3,4可以看出浮动的局限性在于，若要元素排满一行，换行后还要整齐排列，就要子元素的高度一致才行，不然就会出现图三的效果，而inline-block就不会。

3.inline-block存在的小问题：

　　a.上面可以看到用了display:inline-block后，存在间隙问题，间隙为4像素，这个问题产生的原因是换行引起的，因为我们写标签时通常会在标签结束符后顺手打个回车，而回车会产生回车符，回车符相当于空白符，通常情况下，多个连续的空白符会合并成一个空白符，而产生“空白间隙”的真正原因就是这个让我们并不怎么注意的空白符。

　　b.去除空隙的方法：
　　1.对父元素添加，{font-size:0}，即将字体大小设为0，那么那个空白符也变成0px，从而消除空隙
　　现在这种方法已经可以兼容各种浏览器，以前chrome浏览器是不兼容的
图一：

　　c.浏览器兼容性：ie6/7是不兼容 display：inline-block的所以要额外处理一下：
　　在ie6/7下：
　　对于行内元素直接使用{dislplay:inline-block;}
　　对于块级元素：需添加{display:inline;zoom:1;}

4.总结:

　　display：inline-block的布局方式和浮动的布局方式，究竟使用哪个，我觉得应该根据实际情况来决定的：
　　a.对于横向排列东西来说，我更倾向与使用inline-block来布局，因为这样清晰，也不用再像浮动那样清除浮动，害怕布局混乱等等。
　　b.对于浮动布局就用于需要文字环绕的时候，毕竟这才是浮动真正的用武之地，水平排列的是就交给inline-block了。

css-图片（img）的等比例自动缩放

发表评论

img{

width: auto;

height: auto;

max-width: 100%;

max-height: 100%;

}

据父容器的自动缩放，并保持图片原来的比例。这样你设置父容器的大小就可以啦。
