边界角：三角形 [英] Border Corners: Triangle

问题描述

有可能摆脱边界角落的三角形形状吗？ （当使用不同的颜色边框时）

查看此示例：

http://jsfiddle.net/GLsqV/

任何解决方法？基本上我只想让顶部和底部边框继续，而不是所有的混合。

  .borders {
 width：500px; 
 height：500px; 
 background：#efefef; 
 border：10px solid black; 
 border-top：10px solid red; 
 border-bottom：10px solid green; 
} 
  

解决方案

：

  .borders {
 width：500px; 
 height：500px; 
 position：relative; 
 background：#efefef; 
 border-top：10px solid red; 
 border-bottom：10px solid green; 
} 
 
 .borders :: before，
 .borders :: after {
 content：''; 
 position：absolute; 
 width：10px; 
 top：0; 
 bottom：0; 
 background-color：＃000; 
} 
 
 .borders :: before {
 left：0; 
} 
 
 .borders :: after {
 right：0; 
} 
  

JS Fiddle demo 。

或使用嵌套HTML（如果真的必须）：

 < div class =borders> 
< div class =innerBorder left>< / div> 
< div class =innerBorder right>< / div> 
< / div> 
 
 .borders {
 width：500px; 
 height：500px; 
 position：relative; 
 background：#efefef; 
 border-top：10px solid red; 
 border-bottom：10px solid green; 
} 
 
 .borders .innerBorder {
 content：''; 
 position：absolute; 
 width：10px; 
 top：0; 
 bottom：0; 
 background-color：＃000; 
} 
 
 .borders .left {
 left：0; 
} 
 
 .borders .right {
 right：0; 
}

一个单嵌套元素的解决方案， code> border-color 是包装元素的 background-color ，宽度由

$

  
< div class =inner>< / div> 
< / div> 
  

CSS：

  .borders {
 width：500px; 
 height：500px; 
 background-color：＃000; 
 border-top：10px solid red; 
 border-bottom：10px solid green; 
} 
 
 .borders .inner {
 background-color：#efefef; 
 height：100％; 
 margin：0 10px; 
}

Is it possible to get rid of the "triangle" shape in the border corners? (when using different color borders)

See this example:

http://jsfiddle.net/GLsqV/

Any workaround? Basically I just want the top and bottom border to continue, and not have a mix of all of them.

 .borders {  
   width:500px;
   height:500px;
   background:#efefef;
   border:10px solid black;
   border-top:10px solid red;
   border-bottom:10px solid green;
 }​

解决方案

One option using generated content:

.borders {
    width:500px;
    height:500px;
    position: relative;
    background:#efefef;
    border-top:10px solid red;
    border-bottom:10px solid green;
}

.borders::before,
.borders::after {
    content: '';
    position: absolute;
    width: 10px;
    top: 0;
    bottom: 0;
    background-color: #000;
}

.borders::before {
    left: 0;
}

.borders::after {
    right: 0;
}

JS Fiddle demo.

Or with nested HTML (if you really must):

<div class="borders">
    <div class="innerBorder left"></div>
    <div class="innerBorder right"></div>
</div>​

.borders {
    width:500px;
    height:500px;
    position: relative;
    background:#efefef;
    border-top:10px solid red;
    border-bottom:10px solid green;
}

.borders .innerBorder{
    content: '';
    position: absolute;
    width: 10px;
    top: 0;
    bottom: 0;
    background-color: #000;
}

.borders .left {
    left: 0;
}

.borders .right {
    right: 0;
}

JS Fiddle demo.

And a single-nested-element solution in which the left, and right, border-color is the background-color of the wrapping element, and the width controlled by the margin of the descendant:

<div class="borders">
    <div class="inner"></div>
</div>​

CSS:

.borders {
    width:500px;
    height:500px;
    background-color: #000;
    border-top:10px solid red;
    border-bottom:10px solid green;
}

.borders .inner {
    background-color: #efefef;
    height: 100%;
    margin: 0 10px;
}
