如何在对角元素上创建CSS边框 [英] How can I create a CSS border on a diagonal element

问题描述

这是一个例子。 http://jsfiddle.net/52c7t/

简单：我想要获得右边的div，有一个边框像在左边的div。 （我想要边框在右侧div的左侧）

我尝试了100万种不同的组合，但是没能做到。我试图避免做一个图像和这样做与CSS。

感谢您的帮助！

解决方案

简单的解决方案是创建另一个div，因为你的蓝色div已经使用border属性。

新的div本质上是一个蓝色div的克隆，但是会使用CSS width属性被染成红色和一个更大的。

新div的示例：

  .trapezoid-border {
 vertical-align：middle; 
 position：absolute; 
 border-bottom：60px solid red; / *颜色改变将是伪边框颜色* / 
 border-left：45px solid transparent; 
 border-top-left-radius：30px; 
 * border-top-right-radius：15px; 
 * border-bottom-right-radius：3px; 
 height：0; 
 width：53px; / *额外3像素相比.trapezoid类宽度* / 
 display：inline-block; 
 right：1px; 
} 
  

jsFiddle DEMO

Here is an example. http://jsfiddle.net/52c7t/

Simply: I'm trying to get the div on the right side, to have a border like the div on the left. (I'd want the border to be on the left side of the right div)

I tried a million different combinations and haven't been able to do it. I was trying to avoid making an image and do this with css.

Thanks for your help!

解决方案

The simple solution is to create another div since your blue div is already made up using the border property.

That new div is essentially a clone of the blue div, but will be colored red and made a little larger using the CSS width property. This becomes a pseudo border for the blue div.

Example of new div:

.trapezoid-border{
    vertical-align: middle;
    position:absolute;
    border-bottom: 60px solid red;        /* Color Changed will be pseudo-border color */
    border-left: 45px solid transparent;
    border-top-left-radius:30px;
    *border-top-right-radius:15px;
    *border-bottom-right-radius:3px;
    height: 0;
    width: 53px;                       /* Extra 3 pix when compared to .trapezoid class width */
    display: inline-block;
    right:1px;
}
