内容简介：深入理解BootStrap -- 面板(panel)17

1、面板

面板（Panels）是Bootstrap框架新增的一个组件，其主要作用就是用来处理一些其他组件无法完成的功能。同样在不同的版本中具有不同的源码：

☑ Less版本：对应的源码文件是 panels.less

☑ Sass版本：对应的源码文件是 _panels.scss

☑ 编译后的Bootstrap：对应bootstrap.css文件第4995行～第5302行

2、面板–基础面板

基础面板非常简单，就是一个 div 容器运用了“ panel ”样式，产生一个具有边框的文本显示块。由于“ panel ”不控制主题颜色，所以在“ panel ”的基础上增加一个控制颜色的主题“ panel-default ”，另外在里面添加了一个“ div.panel-body ”来放置面板主体内容：

<code class="hljs applescript has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">div</span> <span class="hljs-type" style="box-sizing: border-box;">class</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"panel panel-default"</span>>
    <<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">div</span> <span class="hljs-type" style="box-sizing: border-box;">class</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"panel-body"</span>>我是一个基础面板，带有默认主题样式风格</<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">div</span>>
</<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">div</span>></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li></ul>

运行效果如下：

原理分析：

“ panel “主要对边框，间距和圆角做了一定的设置：

/ bootstrap.css文件第4995行～第5005行 /

<code class="hljs css has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-class" style="box-sizing: border-box; color: rgb(155, 112, 63);">.panel</span> <span class="hljs-rules" style="box-sizing: border-box;">{

3、面板–带有头和尾的面板

基础面板看上去太简单了，Bootstrap为了丰富面板的功能，特意为面板增加“面板头部”和“页面尾部”的效果：

☑ panel-heading：用来设置面板头部样式
☑ panel-footer：用来设置面板尾部样式

<code class="hljs applescript has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">div</span> <span class="hljs-type" style="box-sizing: border-box;">class</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"panel panel-default"</span>>

    <<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">div</span> <span class="hljs-type" style="box-sizing: border-box;">class</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"panel-body"</span>>…</<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">div</span>>
    <<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">div</span> <span class="hljs-type" style="box-sizing: border-box;">class</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"panel-footer"</span>>作者：大漠</<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">div</span>>
</<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">div</span>></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li></ul>

panel-heading 和 panel-footer 也仅仅间距和圆角等样式进行了设置：

4、面板–彩色面板

在基础面板一节中了解到，panel样式并没有对主题进行样式设置，而主题样式是通过panel-default来设置。在Bootstrap框架中面板组件除了默认的主题样式之外，还包括以下几种主题样式，构成了一个彩色面板：

☑ panel-primary ：重点蓝

☑ panel-success ：成功绿

☑ panel-info: 信息蓝

☑ panel-warning ：警告黄

☑ panel-danger ：危险红

使用方法就很简单了，只需要在panel的类名基础上增加自己需要的类名：

<code class="hljs applescript has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">div</span> <span class="hljs-type" style="box-sizing: border-box;">class</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"panel panel-default"</span>>

运行效果如下：

从效果中不难发现，这几个样式只是改变了面板的背景色、文本和边框颜色：具体源码可以查看bootstrap.css文件第5195行～第5302行。

5、面板–面板中嵌套列表组

在上一节，我们介绍了如何在面板中放置表格，现在我们来学习如何在面板中放置列表组，我们简单的来看一个示例：

<code class="hljs xml has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-tag" style="color: rgb(0, 102, 102); box-sizing: border-box;"><<span class="hljs-title" style="box-sizing: border-box; color: rgb(0, 0, 136);">div</span> <span class="hljs-attribute" style="box-sizing: border-box; color: rgb(102, 0, 102);">class</span>=<span class="hljs-value" style="box-sizing: border-box; color: rgb(0, 136, 0);">"panel panel-default"</span>></span>

优化代码：

和嵌套表格一样，如果你觉得这样有间距不好看，你完全可以把列表组提取出来：

同样的道理，Bootstrap将嵌套在面板中的列表组做了一定的样式优化。具体源码可以查看bootstrap.css文件第5031行～第5053行。
