Detailed introduction to Bootstrap panel

1. Panels

Panels (Panels) are a new component of the Bootstrap framework. Its main function is to handle some functions that other components cannot complete. There are also different source codes in different versions:

☑ Less version: the corresponding source code file is panels.less

☑ Sass version: the corresponding source code file is _panels.scss

☑ Compiled Bootstrap: Corresponds to lines 4995 to 5302 of the bootstrap.css file

Basic panel

The basic panel is very simple, it is a div container using "panel" Style, generates a text display block with a border, and adds a "div.panel-body" inside to place the main content of the panel

.panel {
  margin-bottom: 20px;
  background-color: #fff;
  border: 1px solid transparent;
  border-radius: 4px;
  -webkit-box-shadow: 0 1px 1px rgba(0, 0, 0, .05);  box-shadow: 0 1px 1px rgba(0, 0, 0, .05);
}.panel-body {
  padding: 15px;
}

<div class="panel"><div class="panel-body">我是一个基础面板</div></div>

【Components】

The basic panel looks too simple. In order to enrich the functions of the panel, Bootstrap specially adds the "Panel Header" and "Page Footer" effects to the panel:

　☑ panel-heading: used to set the panel head style

　☑ panel-footer: used to set the panel tail style

panel-heading and panel-footer are only spacing and rounded corners and other styles are set

.panel-heading {
  padding: 10px 15px;
  border-bottom: 1px solid transparent;
  border-top-left-radius: 3px;
  border-top-right-radius: 3px;
}.panel-heading > .dropdown .dropdown-toggle {
  color: inherit;
}.panel-title {
  margin-top: 0;
  margin-bottom: 0;
  font-size: 16px;
  color: inherit;
}.panel-title > a {
  color: inherit;
}.panel-footer {
  padding: 10px 15px;
  background-color: #f5f5f5;
  border-top: 1px solid #ddd;
  border-bottom-right-radius: 3px;
  border-bottom-left-radius: 3px;
}

<div class="panel"><div class="panel-heading">小火柴的蓝色理想</div><div class="panel-body">前端学习博客</div><div class="panel-footer">作者：小火柴</div></div>

Color panel

The panel style does not style the theme, but the theme style is Set via panel-default. In the Bootstrap framework, in addition to the default theme style, the panel component also includes the following theme styles, forming a colored panel:

　☑ panel-primary: key blue

　☑ panel- success: success green

☑ panel-info: information blue

☑ panel-warning: warning yellow

☑ panel-danger: danger red

Use The method is very simple. You only need to add the class name you need based on the class name of the panel.

<div class="panel"><div class="panel-heading">小火柴的蓝色理想</div>
<div class="panel-body">前端学习博客</div><div class="panel-footer">作者：小火柴</div></div><div class="panel panel-default"><div class="panel-heading">小火柴的蓝色理想</div><div class="panel-body">前端学习博客</div><div class="panel-footer">作者：小火柴</div></div><div class="panel panel-primary"><div class="panel-heading">小火柴的蓝色理想</div><div class="panel-body">前端学习博客</div><div class="panel-footer">作者：小火柴</div></div>
<div class="panel panel-success">
<div class="panel-heading">小火柴的蓝色理想</div>
<div class="panel-body">前端学习博客</div><div class="panel-footer">作者：小火柴</div>
</div><div class="panel panel-info"><div class="panel-heading">小火柴的蓝色理想</div>
<div class="panel-body">前端学习博客</div><div class="panel-footer">作者：小火柴</div>
</div><div class="panel panel-warning"><div class="panel-heading">小火柴的蓝色理想</div>
<div class="panel-body">前端学习博客</div><div class="panel-footer">作者：小火柴</div></div>
<div class="panel panel-danger"><div class="panel-heading">小火柴的蓝色理想</div>
<div class="panel-body">前端学习博客</div><div class="panel-footer">作者：小火柴</div></div>

Table nesting

Generally speaking, the panel can be understood as a Area, when using the panel, the required content will be placed in the panel-body, which may be pictures, tables or lists, etc.

Add the .table class to the tables in the panel that do not require borders , making the entire panel look more like an overall design. If it is a panel with .panel-body, we add a border above the table, which looks like a separation effect

<div class="panel panel-default"><div class="panel-heading">小火柴的蓝色理想</div><div class="panel-body"><p>前端学习博客</p></div><table class="table"><thead>  <tr><th>#</th><th>名称</th><th>博客数量</th><th>难度</th>  </tr></thead><tbody>  <tr><th scope="row">1</th><td>HTML</td><td>30</td><td>较难</td>  
</tr>  <tr><th scope="row">2</th><td>CSS</td><td>60</td><td>较难</td>  </tr>  <tr><th scope="row">3</th><td>javascript</td><td>200</td><td>很难</td>  </tr></tbody></table></div>

If there is no . panel-body, the panel title will be connected to the table without any gaps

List group nesting

You can simply add a list group with the maximum width to any panel

<div class="panel panel-default"><div class="panel-heading">小火柴的蓝色理想</div>
<div class="panel-body"><p>前端学习博客</p></div><ul class="list-group">
<li class="list-group-item">HTML</li><li class="list-group-item">CSS</li>
<li class="list-group-item" >javascript</li>
<li class="list-group-item">bootstrap</li>
<li class="list-group-item">jquery</li>
</ul>
</div>
