如何使用CSS3 transform skew



演示

  .shape {
width:200px;
height:50px;
-webkit-transform:skew(30deg);
-moz-transform:skew(30deg);
transform:skew(30deg);
background:#000;
margin:20px;
}

没有什么可解释的,这是一个简单的 div 元素,我用 30deg 扭曲,这将导致您预期的形状。



注意:这是一个CSS3属性,因此旧版浏览器以及IE会破坏您的内容,请务必使用 CSS3 Pie 。 / p>




其他实现方法是使用 code>:before 伪和CSS三角形以及内容属性。



演示2 (为演示目的保留红色三角形)



演示3 (颜色已更改)



演示4 (如您所评论的,您需要使用 top:0; for :before :after ,因为当您添加文本时,它将从顶部移动两个三角形。所以为了防止这种情况,使用 top:0;



c> div 元素,并将的两个CSS三角形放置到容器中。这比以上更兼容,如果你要去一个NON CSS3解决方案,你可以选择这个。确保您使用 display:block; 为:之前以及:after 。当然,你可以合并常见的风格,但我保持两个单独的,所以你可以获得容易定制它们单独。

  .shape {
width:200px;
height:50px;
background:#000;
margin:50px;
position:relative;
}

.shape:before {
display:block;
content:;
height:0;
width:0;
border:25px solid#f00;
border-bottom:25px solid transparent;
border-left:25px solid transparent;
position:absolute;
left:-50px;
}

.shape:after {
display:block;
content:;
height:0;
width:0;
border:25px solid#f00;
border-top:25px solid transparent;
border-right:25px solid transparent;
position:absolute;
right:-50px;
}

How about using CSS3 transform skew?

Demo

.shape { 
    width: 200px; 
    height: 50px; 
    -webkit-transform: skew(30deg); 
    -moz-transform: skew(30deg); 
    transform: skew(30deg);
    background: #000;
    margin: 20px;
}

Nothing much to explain here, it's a simple div element, which I've skewed by 30deg which will result in the shape you expected.

Note: It's a CSS3 property, so older browsers, as well as IE will spoil your things, make sure you use CSS3 Pie.


Other way to achieve this is by using :after and :before pseudo and CSS Triangles along with content property.

Demo 2 (Kept red triangles for demo purpose)

Demo 3 (Color Changed)

Demo 4 (As you commented, you need to use top: 0; for :before and :after pseudo as well, because when you add text, it will shift both the triangles from the top. So inorder to prevent that, use top: 0;)

Here, am using a simple div element and placing 2 CSS triangles which are positioned absolute to the container. This is more compatible than above, if you are going for a NON CSS3 solution, you can choose this. Make sure you use display: block; for :before as well as :after. And ofcourse you can merge the common styles but I've kept both separate, so that you can get easability to customize them separately.

 .shape { 
    width: 200px; 
    height: 50px; 
    background: #000;
    margin: 50px;
    position: relative;
}

.shape:before {
    display: block;
    content: "";
    height: 0;
    width: 0;
    border: 25px solid #f00;
    border-bottom: 25px solid transparent;
    border-left: 25px solid transparent;
    position: absolute;
    left: -50px;
}

.shape:after {
    display: block;
    content: "";
    height: 0;
    width: 0;
    border: 25px solid #f00;
    border-top: 25px solid transparent;
    border-right: 25px solid transparent;
    position: absolute;
    right: -50px;
}
