<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>指定选择器</title><style type="text/css">span.red{ color:red;}div#top{ color:blue; }</style></head><body><span class="red">这是个SPAN类名为CLASS</span><span>这是个SPAN</span><div id="top">这是个DIVID是TOP</div><div >这是个DIV</div></body></html>to specify a selector object to define a certain element whose style is limited to the class or id attribute. Its control precision of the element is between the label selector and the id or class Between selectors, it is a very practical selector type
For example, how to control the text of news in the module below
<div><h2 class="news">新闻标题</h2><p class="news">新闻正文</p><span class="news">新闻说明</span><p>其它文件信息</p></div>
css
div p.news{ font-size:18px; color:#FF00FF; }or
p.news{ font-size:18px; color:#00FFFF; }
