CSS实现英文或拼音单词首字母大写，只需要在css样式中加入：
text-transform: capitalize
即可。
测试代码如下：
<!doctype html> <html> <head> <meta charset="utf-8"> <title>英文或拼音单词首字母大写</title> <style> .shou_daxie { text-transform: capitalize } .quan_daxie { text-transform: uppercase } .quan_xiaoxie { text-transform: lowercase } </style> </head> <body> <div class="shou_daxie"> 首字母大写: the bus will depart at the scheduled time regardless of latecomers</div> <div class="quan_daxie"> 字母全实现大写: tHe Bus wIll dePart at the scHeduled Time rEgardless of latecomers</div> <div class="quan_xiaoxie"> 字母全实现小写: tHe Bus wIll dePart at the scHeduled Time rEgardless of latecomers</div> </body> </html>
结果如下：
首字母大写: The Bus Will Depart At The Scheduled Time Regardless Of Latecomers
字母全实现大写: THE BUS WILL DEPART AT THE SCHEDULED TIME REGARDLESS OF LATECOMERS
字母全实现小写: the bus will depart at the scheduled time regardless of latecomers
