每一个HTML文件都是有自己固定的结构的，每一个文件的基本结构又都包含有三个标记：HTML文件标记；HEAD文件头部标记；BODY文件主体标记；接下来我们就来具体看一下HTML基本结构的代码。
基本结构代码：
1 <html>
2 <head>...</head>
3 <body>...</body>
4 </html>
Copy after login
代码讲解：
1. 称为根标签，所有的网页标签都在中。
2.
标签用于定义文档的头部，它是所有头部元素的容器。头部元素有
、<script>、 <style>、<link>、 <meta>等标签，头部标签在下一小节中会有详细介绍。</p>
<p>3. <body></body>标签之间的内容是网页的主要内容，如<h1>、<p>、<a>、<img>等网页内容标签，在这里的标签中的内容会在浏览器中显示出来。</p>
<p>4.<p></p>是文章的段落标签</p>
<p>5.<hx></hx>表示文章标题（x表示数字，为文章标题等级1-6）</p>
<p>6.<em></em>表示斜体</p>
<p>7.<strong></strong>表示加粗</p>
<p>8.<style></p>
<p> span{</p>
<p> 在这里配置样式，比如文字大小，颜色等</p>
<p> }</p>
<p> </style></p>
<p> <span></span>设置单独样式</p>
<p>9.<q></q>引用，会自动加上双引号</p>
<p>10.<blockquote></blockquote>缩进</p>
<p>11.<br />换行</p>
<p>12. 输入空格</p>
<p>13.<hr/>添加水平横线</p>
<p>14.<address></address>输入地址信息（默认以 斜体表示）</p>
<p>15.<code></code>代码标签</p>
<p>16.<pre class="brush:php;toolbar:false"></pre>大段代码标签</p>
<p>17.无序列表</p>
<p><ul></p>
<p> <li>内容</li></p>
<p> <li>内容</li></p>
<p> <li>内容</li></p>
<p></ul></p>
<p>18.有序列表(列表会自动加上序号)</p>
<p> <ol></p>
<p> <li>内容</li></p>
<p> <li>内容</li></p>
<p> <li>内容</li></p>
<p> </ol></p>
<p>19.<div>…</div>：划分区域（独立逻辑）</p>
<p>20.<div id="版块名称">…</div>：划分板块并给板块命名</p>
<p>21.表格展示（没有框线）</p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'><table>
