Question

我想设置一个有序列表的样式，使数字的字体大小比li元素内容大得多。

我已经实现了这一点，但我不知道如何将li元素内容与数字顶部对齐。

看看：

alt text

我已经尝试过给予负极上边距，但这不起作用。另外，ol li有一个上边距但是如果我把它设置为0则它没有做任何事情。我目前的HTML是：

<ol>  
<li>
<p>content</p>
</li> 
<li>
<p>more content</p>
</li> 
</ol>

我的CSS：

ol {
padding-top: 200px;
}
ol li {
color: #EEEDED;
font-size: 35px;
font-weight: bold;
font-style: italic;
margin-top: 5px;
line-height: 1;

}
ol li p {
font-size:  11px;
color:  #444444;
font-weight: normal;
font-style: normal;
line-height: 1.7em;
}

任何想法??

Answer 1

这可以通过以下方式解决：

将display: inline-block应用于P元素
将vertical-align: middle应用于P元素

这使P元素能够共享内联和块级特征，从而允许vertical-align正确运行（在整个文本块上，作为一个整体）。

示例CSS：

ol { margin-left: 100px; }

li { font-size: 4em; }

p { display: inline-block; vertical-align: text-top; font-size: 0.25em; line-height: 1.5; padding-left: 2em; }

div { width: 50%; margin-left: -25%; left: 50%; position: relative; }

示例标记：

<div>
  <ol>
    <li>

注意：display: inline-block在Firefox 2中不起作用 - 另一种方法是使用display: -moz-inline-box

编辑：替换'vertical-align：middle;'使用'vertical-align：text-top;'将数字与每个段落的顶部对齐。

            </ol>

Answer 3

您可以在li和top属性上使用position：relative来实现此目的。例如：

ol li p
{
    position:relative;
    top : 20px;
}

Answer 4

这是您想要的工作示例：

已编辑：p标记在OL数字顶部对齐

Answer 5

我遇到了类似的问题，但无法更改HTML，所以这里有一个不同的想法：删除list-style并设置css counter。

我的代码：

<ol>
    <li>something</li>
    <li>Something else</li>
</ol>

和（SCSS）：

ol {
    list-style: none;
    counter-reset: contador-lista;
    li {
            counter-increment: contador-lista;
            &:before {
                    //place your different styling here!
                    content: counter(contador-lista) ".";
            }
    }
}

使用与内容不同的字体大小设置有序列表编号的样式
