深入理解BootStrap -- 面板(panel)17

阿新 • • 發佈：2019-02-17

1、面板

面板（Panels）是Bootstrap框架新增的一個元件，其主要作用就是用來處理一些其他元件無法完成的功能。同樣在不同的版本中具有不同的原始碼：

☑ Less版本：對應的原始碼檔案是 panels.less

☑ Sass版本：對應的原始碼檔案是 _panels.scss

☑ 編譯後的Bootstrap：對應bootstrap.css檔案第4995行～第5302行

2、面板–基礎面板

基礎面板非常簡單，就是一個div容器運用了“panel”樣式，產生一個具有邊框的文字顯示塊。由於“panel”不控制主題顏色，所以在“panel”的基礎上增加一個控制顏色的主題“panel-default

”，另外在裡面添加了一個“div.panel-body”來放置面板主體內容：

<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>>我是一個基礎面板，帶有預設主題樣式風格</<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>

原理分析：

“panel“主要對邊框，間距和圓角做了一定的設定：

/bootstrap.css檔案第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–帶有頭和尾的面板

基礎面板看上去太簡單了，Bootstrap為了豐富面板的功能，特意為面板增加“面板頭部”和“頁面尾部”的效果：

☑ panel-heading：用來設定面板頭部樣式
☑ panel-footer：用來設定面板尾部樣式

<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-heading"</span>>圖解CSS3</<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>

原理分析：

panel-heading和panel-footer也僅僅間距和圓角等樣式進行了設定：

4、面板–彩色面板

在基礎面板一節中瞭解到，panel樣式並沒有對主題進行樣式設定，而主題樣式是通過panel-default來設定。在Bootstrap框架中面板元件除了預設的主題樣式之外，還包括以下幾種主題樣式，構成了一個彩色面板：

☑ panel-primary：重點藍

☑ panel-success：成功綠

☑ panel-info:資訊藍

☑ panel-warning：警告黃

☑ panel-danger：危險紅

使用方法就很簡單了，只需要在panel的類名基礎上增加自己需要的類名：

<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>>

從效果中不難發現，這幾個樣式只是改變了面板的背景色、文字和邊框顏色：具體原始碼可以檢視bootstrap.css檔案第5195行～第5302行。

5、面板–面板中巢狀列表組

在上一節，我們介紹瞭如何在面板中放置表格，現在我們來學習如何在面板中放置列表組，我們簡單的來看一個示例：

<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>

優化程式碼：

和巢狀表格一樣，如果你覺得這樣有間距不好看，你完全可以把列表組提取出來：
