比如这个。跟HTML5有关么？

回复内容：

右键查看源代码，line 28：http://iapps.geekpark.net/html_page/css/style.css?v=2
style.css，line 134： ::-moz-selection{ background: #FF5E99; color:#fff; text-shadow: none; } ::selection { background:#FF5E99; color:#fff; text-shadow: none; }

这是个CSS3的属性。
目前并非所有浏览器都支持这个属性（IE系列中IE9以上支持，非IE系列的支持CSS3的浏览器都支持该属性。具体对该属性的支持情况说不上来请搜索各浏览器对CSS3的支持情况）。
不同浏览器的写法不一致，比如上面“-moz-selection”是mozilla专用的写法。

这个无法用css控制，显示效果跟浏览器内核有关确切的说，是CSS3 css的效果设置吧
