本文章介绍了解jquery+CSS text-transform 属性实现切换选项卡效果，有需要的朋友可参考一下。
Css有个这么好的属性就是text-transform：uppercase。
这个属性会改变元素中的字母大小写，而不论源文档中文本的大小写。如果值为 capitalize，则要对某些字母大写，但是并没有明确定义如何确定哪些字母要大写，这取决于用户代理如何识别出各个“词”。
none默认。定义带有小写字母和大写字母的标准的文本。capitalize文本中的每个单词以大写字母开头。uppercase定义仅有大写字母。lowercase定义无大写字母，仅有小写字母。inherit规定应该从父元素继承 text-transform 属性的值。
所有浏览器都支持 text-transform 属性。
注释：任何的版本的 Internet Explorer （包括 IE8）都不支持属性值 "inherit"。
代码如下
