Bootstrap 圖標

簡介

在本教程中，您將學(xué)習(xí)如何使用 Bootstrap 2.0 工具包來創(chuàng)建圖標。Bootstrap 圖標由 Glyphicons 提供。如果您在項目中使用這些圖標，請確保提供 Glyphicons 的鏈接。

作為 CSS Sprite 使用

所有的圖標圖像都捆綁到一起，并通過 background-position CSS 屬性使用。圖像文件是 glyphicons-halflings.png，位于 Bootstrap 主文件夾下的 img 文件夾。圖標的樣式以及背景位置是在 bootstrap.css 的行號 1168 到 1544 中規(guī)定。請注意，為避免沖突，所有的圖標 class 都以 "icon-" 為前綴。Bootstrap 2.0 中定義了 120 個圖標 class。

如何在您自己的站點或 app 中使用圖標

下面是在站點或 app 中使用圖標的通用語法：

 <i class="icon_class_name"></i>

其中 "icon_class_name" 是在 bootstrap.css 中定義的圖標 class 的名稱（例如：icon-music、icon-star、icon-user 等）。

如果您想要使用白色圖標，然后添加一個額外的 icon-white class，如下所示： 

<i class="icon_class_name icon-white"></i>  </i>

如果您想要在使用圖標時帶上一些字符串，記得在 之后添加一些空格。在按鈕中使用圖標或者一些導(dǎo)航鏈接中可能會出現(xiàn)這種情況。
