h1 html标题标签
网页内容中，比如一篇文章标题，一般采用
标签来标记布局，这样显示标题在HTML中重要性，同时也考虑到告诉搜索引擎标签内内容为标题很重要。
一、h1语法结构
以
开始,以
结束的一对有开始有闭合的标签组。
同样h1标签也可以使用class和id引入外部CSS样式。
<h1 class=”yanshi”>文章标题</h1>
<h1 id=”abc”>主题标题</h1>
登录后复制
二、h1标题标签特点与使用建议(用什么地方)
html h1标题标签常常一个网页中最好只使用一次即可，不要使用两次或两次以上，这样才能符合h1重要和唯一性。其它标题元素比如h2标签、h3标签、h4标签可以在一个网页中多次使用。
h1用什么地方，一般标记一个网页中文章标题、主题标题。
三、默认h1标签
默认初始化状态下,h1标签字体是加粗的，而且字体大小也非常大。通常不同浏览器也是有着大小不同区别，所以实际DIV CSS布局时，我们还是需要提前或要使用时候对其设置需要的CSS样式（比如字体大小、是否加粗）等具体需求具体再设置
四、标题标签与网页标题标签区分
html h1与html title标签虽然都叫标题标签，但一般
放网页标题，<h1>放文章标题。所以本质还是有区别的。</p><p>五、html h1简单用法</p><p>HTML源代码：</p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'><!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>网页标题 ThinkCSS</title>
<style>
.abc{ color:#F00;font-size:26px}
</style>
</head>
<body>
<h1 class="abc">文章标题</h1>
<p>文章内容</p>
<p>文章内容</p>
</body>
</html></pre><div class="contentsignin">登录后复制</div></div><p>这里使用h1标签同时使用class设置CSS。</p>
