你可以很容易地用jQuery-Columns Plugin来做到这一点，例如，用一个。mylist类来分割一个ul

$('.mylist').cols(2);

下面是jsfiddle的一个实例

我喜欢这个比CSS更好，因为在CSS解决方案中，不是所有东西都垂直对齐到顶部。

下面是一个简单的方法，使用简单的CSS创建一个多列列表。如果需要，样式标记显然可以放入CSS中。

<p>Materials List</p>
<ul style="display: inline-block; float: left">
    <u>Item Description<u>
    <li>1/2" x 4' wood dowel</li>
    <li>1/2" x 12"  PVC pipe</li>
    <li>1/2" PVC pipe end cap</li>
    <li>7/16" x 3" light duty expansion spring</li>
    <li>6" plastic zip ties</li>
    <li>Light weight antenna</li>
</ul>
<div style="display: inline-block; margin-left: 1em">
    <u>Qty</u>
    <div style="text-indent: 0.5em">3</div>
    <div style="text-indent: 0.5em">1</div>
    <div style="text-indent: 0.5em">1</div>
    <div style="text-indent: 0.5em">2</div>
    <div style="text-indent: 0.5em">8</div>
    <div style="text-indent: 0.5em">1</div>
</div>
<p></p>

上面答案中的遗留解决方案不适合我，因为我想影响页面上的多个列表，而答案假设一个列表加上它使用了相当多的全局状态。在这种情况下，我想改变<section class="list-content">中的每个列表:

const columns = 2;
$("section.list-content").each(function (index, element) {
    let section = $(element);
    let items = section.find("ul li").detach();
    section.find("ul").detach();
    for (let i = 0; i < columns; i++) {
        section.append("<ul></ul>");
    }
    let lists = section.find("ul");
    for (let i = 0; i < items.length; i++) {
        lists.get(i % columns).append(items[i]);
    }
});

假设多列布局可以很好地与居中布局，证明网格布局与水平间隙。

p { text-align: justify; } ul { display: grid; grid-template-columns: repeat(3, auto); justify-content: space-around; gap: 0 3em; text-transform: capitalize; } <p>In publishing and graphic design, Lorem ipsum is a placeholder text commonly used to demonstrate the visual form of a document or a typeface without relying on meaningful content. Lorem ipsum may be used as a placeholder before final copy is available.</p> <ul> <li>one</li> <li>two</li> <li>three</li> <li>four</li> <li>five</li> <li>six</li> <li>seven</li> <li>eight</li> <li>nine</li> <li>ten</li> </ul> <p>In publishing and graphic design, Lorem ipsum is a placeholder text commonly used to demonstrate the visual form of a document or a typeface without relying on meaningful content. Lorem ipsum may be used as a placeholder before final copy is available.</p>

几年后再来一个答案!

HTML:

<ul id="double"> <!-- Alter ID accordingly -->
  <li>CSS</li>
  <li>XHTML</li>
  <li>Semantics</li>
  <li>Accessibility</li>
  <li>Usability</li>
  <li>Web Standards</li>
  <li>PHP</li>
  <li>Typography</li>
  <li>Grids</li>
  <li>CSS3</li>
  <li>HTML5</li>
  <li>UI</li>
</ul>

CSS:

ul{
  width:760px;
  margin-bottom:20px;
  overflow:hidden;
  border-top:1px solid #ccc;
}
li{
  line-height:1.5em;
  border-bottom:1px solid #ccc;
  float:left;
  display:inline;
}
#double li  { width:50%;}
#triple li  { width:33.333%; }
#quad li    { width:25%; }
#six li     { width:16.666%; }

这对我来说是一个完美的解决方案，我找了很多年:
