CSS三角形自定义边框颜色 [英] CSS triangle custom border color

问题描述

尝试为我的css三角形（边框）使用自定义十六进制颜色。但是由于它使用边界属性，我不确定如何去做这个。我想避开javascript和css3只是因为兼容性。我试图让三角形有白色背景与1px边框（三角形的有角的两侧）与颜色＃CAD5E0。这可能吗？这是我到目前为止：

  .container {
 margin-left：15px; 
 width：200px; 
 background：#FFFFFF; 
 border：1px solid＃CAD5E0; 
 padding：4px; 
 position：relative; 
 min-height：200px; 
} 
 
 .container：after {
 content：''; 
 display：block; 
 position：absolute; 
 top：10px; 
 left：100％; 
 width：0; 
 height：0; 
 border-color：transparent透明＃CAD5E0; 
 border-style：solid; 
 border-width：10px; 
} 
  

我的小提琴：

Attempting to use a custom hex color for my css triangle (border). However since it uses border properties I am unsure how to go about doing this. I would like to steer clear of javascript and css3 simply because of compatibility. I am trying to have the triangle have a white background with a 1px border (around the angled sides of the triangle) with color #CAD5E0. Is this possible? Here's what I have so far:

.container {
    margin-left: 15px;
    width: 200px;
    background: #FFFFFF;
    border: 1px solid #CAD5E0;
    padding: 4px;
    position: relative;
    min-height: 200px;
}

.container:after {
    content: '';
    display: block;
    position: absolute;
    top: 10px;
    left: 100%;
    width: 0;
    height: 0;
    border-color: transparent transparent transparent #CAD5E0;
    border-style: solid;
    border-width: 10px;
}​

解决方案

You actually have to fake it with two triangles....

.container {
    margin: 15px 30px;
    width: 200px;
    background: #fff;
    border: 1px solid #a00;
    position: relative;
    min-height: 200px;
    padding: 20px;
    text-align: center;
    color: #fff;
    font: bold 1.5em/180px Helvetica, sans-serif;
    text-shadow: 0 0 1px #000;
}

.container:after,
.container:before {
    content: '';
    display: block;
    position: absolute;
    left: 100%;
    width: 0;
    height: 0;
    border-style: solid;
}

.container:after {
    top: 10px;
    border-color: transparent transparent transparent #fdd;
    border-width: 10px;
}

.container:before {
    top: 9px;
    border-color: transparent transparent transparent #a00;
    border-width: 11px;
}
