接触前端（好大气的名字啊）已经一个多月了，看了很多视频和博客，有了一定的感性认识，但还是需要总结一下以便系统化所学习的知识，就从html标签开始吧。关于标签，谈论最多的就是简洁和语义化。简洁指html标签仅仅负责把页面中的内容进行正确标示即可，而对内容的表现形式则统统交由css负责。语义化本不应成为问题，因为就像人与人之间的交流需要有意义的语言一样，html文档作为人与浏览器交流的语言自然是有意义的，但这并不能使所有人都遵循（类似于有了普通话，但各地方言依然流行，因为有时都可以达到一样的目的，所以人们总是按其最习惯的方式来进行）。简洁的问题到css是在进行总结，现在先谈谈语义化的问题。
w3school中共有117个标签，其中html5有16个不支持，29个新标签，以及从以前延续下来的72个标签。
今天先大致分类（按照我对其语义的理解）一下这72个“旧”标签吧，在此基础上以后分步进行语义辨析：
4个框架标签：,,,
1 <!DOCTYPE>2 <html>3 <head>4 <title>标题</title>5 </head>6 <body>7 内容。。。8 </body>9 </html>
登录后复制
这里面的
标签是必须出现在<head>标签内的，但并不属于我所说的第一部分。</p> 4个只能（但并不必须）或必须在<head></head>标签之内出现的标签：<title>,<meta>,<base>,<link> <p class="sycode"> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'>1 <head>2 <title>标题</title>3 <meta http-equiv="content-type" content="text/html; charset=utf-8">4 <base href="#" />5 <link rel="stylesheet" type="text/css" href="#" />6 </head></pre><div class="contentsignin">登录后复制</div></div> </p> 22个与文本有关的标签：<abbr>,<b>,<bdo>,<blockquote>,<cite>,<code>,<dfn>,<del>,<em>,<h1>-<h6>,<i>,<ins>,<p>,<div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">,<q>,<small>,<smap><sub>,<sup>,<span>,<strong>,<var>,这么多标签与文本有关也传递出一个信息，那就是文本内容才是网页中最重要的部分。 10个与表格有关的标签：<caption>,<col>,<colgroup>,<table>,<th>,<tr>,<td>,<thead>,<tbody>,<tfoot>。 <p class="sycode"> <pre class='brush:php;toolbar:false;'><table> <caption>每月的存款</caption> <colgroup span="3"> <col span="1" style="background-color:red"> <col span="3" style="background-color:blue"> <tr> <th>月份</th> <th>一月</th> <th>二月</th> <th>三月</th> </tr> <tr> <td>存款</td> <td>1000元</td> <td>1000元</td> <td>1000元</td> </tr></table></pre><div class="contentsignin">登录后复制</div></div> </p> <p class="sycode"> <div class="code" style="position:relative;
