		<title>列表--简介</title>
		<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">

Lists--unordered lists, ordered lists

bootstrap supports several list styles

Unordered lists The usage of ordered lists is the same as what we usually use (unordered lists use ul, ordered lists use ol tags). In terms of style, Bootstrap has only made some subtle optimizations on this basis. Please view bootstrap.css for the source code. Lines 569 to 579 of the file:

ul,
ol {
  margin-top: 0;
  margin-bottom: 10px;
}
ul ul,
ol ul,
ul ol,
ol ol {
  margin-bottom: 0;
}

From the source code, we can know that Bootstrap only made some adjustments to the margin for the list.

List nesting

Lists can also be nested in Bootstrap.

List--Go to the list

You can see that by default in Bootstrap, unordered list and ordered list It has bullet points, but in many cases in actual work, our lists do not need this number, such as when using unordered lists for navigation. Bootstrap has been very considerate for many developers. By adding a class name ".list-unstyled" to the unordered list, the default list style can be removed. /*For the source code, please view lines 580~583 of the bootstrap.css file*/

.list-unstyled {
padding-left: 0;
list-style: none;
}

Copy after login

As can be seen from the example, in addition to the item number, the default left padding# of the list will also be included. ##Alsocleared0.

List--inline list

Bootstrap implements an inline list by adding the class name "

.list-inline" just like a list. To put it simply, That is replace the vertical list with a horizontal list, and remove the bullets (numbers) , keep the horizontal display. It can also be said that inline lists are born for creating horizontal navigation. /*View the source code for lines 584~593 of the bootstrap.css file*/

.list-inline {
padding-left: 0;
margin-left: -5px;
list-style: none;
}
.list-inline > li {
display: inline-block;
padding-right: 5px;
padding-left: 5px;
}

Copy after login

Look at an example:

<ul class="list-inline">
    <li>W3cplus</li>
    <li>Blog</li>
    <li>CSS3</li>
    <li>jQuery</li>
    <li>PHP</li>
</ul>

List--Definition list

bootstrap supports several list styles

For the definition list, Bootstrap did not make too many adjustments. It just adjusted

line spacing, margin and font bold Effect. /*For the source code, please view lines 594~607 of the bootstrap.css file*/

dl {
margin-top: 0;
margin-bottom: 20px;
}
dt,
dd {
line-height: 1.42857143;
}
dt {
font-weight: bold;
}
dd {
margin-left: 0;
}

For the use of definition lists, it is actually very simple. It is the same as our previous method of using definition lists:

<dl>
    <dt>W3cplus</dt>
    <dd>一个致力于推广国内前端行业的技术博客</dd>
    <dt>seashen.cn</dt>
    <dd>一个真心在做HTML5教育的网站</dd>
</dl>

List--Horizontal definition list

bootstrap supports several list styles

Horizontal definition list Just like the inline list, Bootstrap can add the class name "

. dl-horizontal" implements horizontal display effects for definition lists. /*For the source code, please view lines 608~621 of the bootstrap.css file*/

@media (min-width: 768px) {
.dl-horizontal dt {
float: left;
width: 160px;
overflow: hidden;
clear: left;
text-align: right;
text-overflow: ellipsis;
white-space: nowrap;
  }
.dl-horizontal dd {
margin-left: 180px;
  }
}

Copy after login

A media query is added here. In other words, only when the screen

is larger than 768px, adding the class name ".dl-horizontal" will have the horizontal definition list effect. The main methods of implementation: 1. Set dt to a left float and set a width of 160px 2. Set dd to a margin-left value of 180px to achieve a horizontal effect 3. When the title width exceeds 160px , three ellipses

will be displayed and their usage is as follows:

<dl class="dl-horizontal">
    <dt>W3cplus</dt>
    <dd>一个致力于推广国内前端行业的技术博客。它以探索为己任，不断活跃在行业技术最前沿，努力提供高质量前端技术博文</dd>
    <dt>seashen.cn</dt>
    <dd>一个专业的HTML5网站</dd>
    <dt>我来测试一个标题，我来测试一个标题</dt>
    <dd>我在写一个水平定义列表的效果，我在写一个水平定义列表的效果</dd>
</dl>

Copy after login

When you shrink your browser screen, the horizontal definition list will return to its original state.
