使用CSS创建多色条

Question

我想创建一个如下图所示的多色条：

是否可以创建实现此目的的CSS？我已设法使用以下CSS创建颜色渐变：

.gold{
  background-color: #faa732;
  background-image: -moz-linear-gradient(top, #eab92d, #c79810);
  background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#eab92d), to(#c79810));
  background-image: -webkit-linear-gradient(top, #eab92d, #c79810);
  background-image: -o-linear-gradient(top, #eab92d, #c79810);
  background-image: linear-gradient(to bottom, #eab92d, #c79810);
  background-repeat: repeat-x;
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#fffbb450', endColorstr='#fff89406', GradientType=0);
}

.blue {
  background-color: #faa732;
  background-image: -moz-linear-gradient(top, #034a96, #0663c7);
  background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#034a96), to(#0663c7));
  background-image: -webkit-linear-gradient(top, #034a96, #0663c7);
  background-image: -o-linear-gradient(top, #034a96, #0663c7);
  background-image: linear-gradient(to bottom, #034a96, #0663c7);
  background-repeat: repeat-x;
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#fffbb450', endColorstr='#fff89406', GradientType=0);
}

.green {
  background-color: #faa732;
  background-image: -moz-linear-gradient(top, #0D7626, #0a611e);
  background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#0D7626), to(#0a611e));
  background-image: -webkit-linear-gradient(top, #0D7626, #0a611e);
  background-image: -o-linear-gradient(top, #0D7626, #0a611e);
  background-image: linear-gradient(to bottom, #0D7626, #0a611e);
  background-repeat: repeat-x;
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#fffbb450', endColorstr='#fff89406', GradientType=0);
}

我只是不确定如何使它们像图片中那样彼此相邻，以及如何使用不同的百分比宽度（例如蓝色渐变50％的条纹，绿色渐变40％，金色渐变10％ ）。

Answer 1

您需要的是:before和:after个伪元素。他们将内容添加到开头并结束内部给定的选择器。

HTML：

<div></div>

CSS：

div {
  height: 2em;

  background-color: #faa732;
  background-image: -moz-linear-gradient(top, #eab92d, #c79810);
  background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#eab92d), to(#c79810));
  background-image: -webkit-linear-gradient(top, #eab92d, #c79810);
  background-image: -o-linear-gradient(top, #eab92d, #c79810);
  background-image: linear-gradient(to bottom, #eab92d, #c79810);
  background-repeat: repeat-x;
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#fffbb450', endColorstr='#fff89406', GradientType=0);
}

div:before {
  height: 2em;
  width: 50%;
  display: block;
  content: "";
  float: left;

  background-color: #faa732;
  background-image: -moz-linear-gradient(top, #034a96, #0663c7);
  background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#034a96), to(#0663c7));
  background-image: -webkit-linear-gradient(top, #034a96, #0663c7);
  background-image: -o-linear-gradient(top, #034a96, #0663c7);
  background-image: linear-gradient(to bottom, #034a96, #0663c7);
  background-repeat: repeat-x;
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#fffbb450', endColorstr='#fff89406', GradientType=0);
}

div:after {
  height: 2em;
  width: 40%;
  display: block;
  content: "";
  float: right;

  background-color: #faa732;
  background-image: -moz-linear-gradient(top, #0D7626, #0a611e);
  background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#0D7626), to(#0a611e));
  background-image: -webkit-linear-gradient(top, #0D7626, #0a611e);
  background-image: -o-linear-gradient(top, #0D7626, #0a611e);
  background-image: linear-gradient(to bottom, #0D7626, #0a611e);
  background-repeat: repeat-x;
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#fffbb450', endColorstr='#fff89406', GradientType=0);
}

PS在实际使用中，你应该将它应用于类或id，而不是元素选择器。

Answer 2

嗯..如果你问我认为你在问什么，就这么简单。 HTML：

<table>
    <tr> 
        <td class="color1"></td>
        <td class="color2"></td>
        <td class="color3"></td>
    </tr>
</table>    

CSS：

table { border-collapse: collapse; }
td{
   width: 100px;
   height: 20px;
   padding: 0px;
}
.color1{
  background-color: red;
}
.color2{
  background-color: blue;
}
.color3{
   background-color: yellow;
}

或类似的东西。

这就是它的样子。您可以编辑高度/宽度/颜色/类名称。

Answer 3

您也可以使用网格，例如：

<div class="my-grid">
<div class="col-1-3">(be yellow)</div>
<div class="col-2-3">(be green)</div>
<div class="col-3-3">(be blue)</div>
</div>

然后在CSS中

.my-grid {
width: 100%;
}
.col-1-3 {
width: 33%;
float: left;
background-color: yellow;
}
.col-2-3 {
width: 33%;
float: left;
background-color: green;
}
.col-3-3 {
width: 33%;
float: left;
background-color: blue;
}
.my-grid:after {
clear:both;
}

请务必执行my-grid：部分之后。

我更喜欢桌子而不是div。试试这个

<table>
<tr width="300px">
<td style="background:#50c690; width:250px;height:25px;"></td><td style="background:#FE6; width:50px;height:25px;"></td>
</tr>
