为bootstrap添加更多自定义图标

From: http://blog.csdn.net/mengxiangfeiyang/article/details/45224731

Twitter Bootstrap 真是前端开发的瑞士军刀，作为基于 HTML，CSS 和JavaScript 的简洁灵活的前端框架及交互模块集合，让我这样的半吊子 PHPer 都能很轻松地写出一张还算漂亮的页面来。干净整洁有木有！小清新有木有！Web 后端都逆袭了有木有！

Bootstrap 默认自带了由 Glyphicons 提供的 140 个灰/白图标，很好看，然而，很不够用啊！无法满足项目饥渴的需求啊！连个电话的图标都没有，哥曾经在推上@这套图标的作者，过了大概 5 个月这哥们回复我说那个 phone icon 做好了。。。

FamFamFam Silk Icon 是一套免费的图标，它包含了 1000 多个精美的彩色的 icons（全部图标一览）。如果能用 Bootstrap 的方式来调用这些图标，使用到我们的项目中，肯定能把需求全部满足了。

一、下载 FamFamFam 图标

下载：点击下载

二、合并雪碧图

并不是所有的 1000 多枚图标我们都用得上，为了减小图片大小，我们从下载的图标中挑出我们需要的，然后进行 Sprite 在线合并。

1. 打开这个网站：http://spritegen.website-performance.org/
2. 选择你要合并的图标准备上传
3. 修改以下配置

Build Direction: Horizontal
Horizontal Offset: 5px
Vertical Offset: 5px
CSS Prefix: cus-

4. 提交上传

大约 30 秒后，我们就能得到合并后的雪碧图，以及相关 CSS 代码了。

总结

Bootstrap 是一套前端开发利器，它可以帮助我们加速项目开发，让样式和交互拥有一致的设计和实现方法。于是开发者不需要在外观上花费过多时间，能将精力集中于更重要的功能。Sroan 曾经问我：“大家都用这套框架，那做出来网站岂不是都长得一样了？”

确实，如果完全采用 Bootstrap 的默认样式，就会有很多界面元素雷同。但我们终究是要写自己的 CSS 样式的，不然，不论用什么框架，总会有雷同的问题。Bootstrap 带来的只是一套前端规范和开发约束，它定义了我们的合作方式，让界面元素的命名有规律可循。更何况任何人都可以基于 Bootstrap 建立可扩展的前端工具包，或者在它的基础上启动属于自己的框架。自定义图标就是一个开始。
