How to style the number on a html list?
提问by Filype
Is it possible to style or increase the size of the numbers onlyon a ordered list?
是否可以仅在有序列表上设置样式或增加数字的大小？
I am planning on turning a ordered list olinto something like wikihowsteps using CSS only.
我计划仅使用 CSS将有序列表ol转换为类似于wikihow步骤的内容。
Here is a example to play with: http://jsfiddle.net/ejRzy/1/

It can be done using CSS3 but not 100% cross browser (namely IE7). using the pseudo :before element and counter-reset and counter-increment you can hide the list-style and create your own.
它可以使用 CSS3 完成，但不能 100% 跨浏览器（即 IE7）。使用伪 :before 元素和计数器重置和计数器增量，您可以隐藏列表样式并创建自己的列表样式。
here is an article outlining how: Styling ordered list numbers
这是一篇概述方法的文章：样式化有序列表编号
and hereis a demo built from that article.
而这里是那篇文章建立了一个演示。
Also in case of the dreaded link rot - here is the main CSS code required (this can be applied to any ordered list)
同样在可怕的链接腐烂的情况下 - 这是所需的主要 CSS 代码（这可以应用于任何有序列表）
ol {
counter-reset:li; /* Initiate a counter */
margin-left:0; /* Remove the default left margin */
padding-left:0; /* Remove the default left padding */
}
ol > li {
position:relative; /* Create a positioning context */
margin:0 0 6px 2em; /* Give each list item a left margin to make room for the numbers */
padding:4px 8px; /* Add some spacing around the content */
list-style:none; /* Disable the normal item numbering */
border-top:2px solid #666;
background:#f6f6f6;
}
ol > li:before {
content:counter(li); /* Use the counter as content */
counter-increment:li; /* Increment the counter by 1 */
/* Position and style the number */
position:absolute;
top:-2px;
left:-2em;
-moz-box-sizing:border-box;
-webkit-box-sizing:border-box;
box-sizing:border-box;
width:2em;
/* Some space between the number and the content in browsers that support
generated content but not positioning it (Camino 2 is one example) */
margin-right:8px;
padding:4px;
border-top:2px solid #666;
color:#fff;
background:#666;
font-weight:bold;
font-family:"Helvetica Neue", Arial, sans-serif;
text-align:center;
}
li ol,
li ul {margin-top:6px;}
ol ol li:last-child {margin-bottom:0;}?
This code will produce a custom ordered list; albeit not the style you asked for. I will leave the customization work upto you :) cheers
此代码将生成自定义有序列表；虽然不是你要求的风格。我会把定制工作留给你:) 欢呼

kind of.... style your ordered list with the font size you want for the numbers, then wrap all your list items in spans, and give them a different style.
有点......用你想要的数字字体大小来设计你的有序列表，然后用跨度包装你的所有列表项，并给它们一个不同的样式。
