我正在尝试对有序列表中的数字进行样式设置,我想添加背景颜色、边框半径和颜色,以便它们与我正在使用的设计相匹配:
我想这是不可能的,我必须为每个数字使用不同的图像,即
ol li:first-child {list-style-image:url('1.png')};
ol li:nth-child(2) {list-style-image:url('2.png');}
etc...
有更简单的解决方案吗?
您可以使用 CSS 计数器 结合
:before
伪元素来完成此操作:
ol {
list-style: none;
counter-reset: item;
}
li {
counter-increment: item;
margin-bottom: 5px;
}
li:before {
margin-right: 10px;
content: counter(item);
background: lightblue;
border-radius: 100%;
color: white;
width: 1.2em;
text-align: center;
display: inline-block;
}
<ol>
<li>item</li>
<li>item</li>
<li>item</li>
<li>item</li>
</ol>
我一直在寻找不同的东西,并在 CodePen 中找到了这个示例;
试试这个:http://codepen.io/sawmac/pen/txBhK
body {
font-size: 1.2em;
font-family: "Helvetica Neue", Helvetica, sans-serif;
margin: 50px;
}
.custom-counter {
margin: 0;
padding: 0;
list-style-type: none;
}
.custom-counter li {
counter-increment: step-counter;
margin-bottom: 5px;
}
.custom-counter li::before {
content: counter(step-counter);
margin-right: 20px;
font-size: 80%;
background-color: rgb(180, 180, 180);
color: white;
font-weight: bold;
padding: 3px 8px;
border-radius: 11px;
}
<ol class="custom-counter">
<li>This is the first item</li>
<li>This is the second item</li>
<li>This is the third item</li>
<li>This is the fourth item</li>
<li>This is the fifth item</li>
<li>This is the sixth item</li>
</ol>
2021更新,您可以在最近的浏览器中使用
::marker
伪元素选择器:https://developer.mozilla.org/en-US/docs/Web/CSS/::marker
li::marker {
color: red;
}
li {
color: blue;
}
<ol>
<li>item</li>
<li>item</li>
<li>item</li>
<li>item</li>
</ol>
简单的解决方案是:
ol li::marker {
font-weight: bold;
}
适用于 Chrome。
