1、基本标签属性

 1 <html> 2 <!--属性和属性值对大小写不敏感。 3 不过,万维网联盟在其 HTML 4 推荐标准中推荐小写的属性/属性值。 4 而新版本的 (X)HTML 要求使用小写属性。 5  --> 6  7 <body> 8  9 <!-- hello this is a comment-->10 11 <h1 id="This-is-heading">This is heading 1</h1>12 <h2 id="This-is-heading">This is heading 2</h2>13 <h3 id="This-is-heading">This is heading 3</h3>14 <h4 id="This-is-heading">This is heading 4</h4>15 <h5 id="This-is-heading">This is heading 5</h5>16 <h6 id="This-is-heading">This is heading 6</h6>17 18 <hr><!--绘制水平线-->19 20 <a href="http://www.baidu.com"> link_baidu </a>21 22 <br>23 <body bgcolor="#e6e6e6">24 25 26 <p> this is paragraph 1 </p>27 <p> this is paragraph 2 </p>28 <p> this is paragraph 3 </p>29 30 <img  src="/static/imghw/default1.png"  data-src="/i/eg_w3school.gif"  class="lazy"/ alt="1、HTML基础学习 第一天_html/css_WEB-ITnose" >31 <img  src="/static/imghw/default1.png"  data-src="/i/eg_w3school.gif"  class="lazy"    style="max-width:90%"  style="max-width:90%" / alt="1、HTML基础学习 第一天_html/css_WEB-ITnose" >32 <br/>33 <br/>34 <br/>35 36 37 normal38 <br/>39 <b> bold </b>40 <br/>41 <strong> strong </strong>42 <br/>43 <big> big font </big>44 <br/>45 <small> small font </small>46 <br/>47 <i> italic font </i>48 <br/>49 what's the  <sub> fuck </sub>50 <br/>51 what's the  <sup> fuck </sup>52 <br/>53 <i> what's the  <sup> fuck </sup> </i>54 55 <p>pre 标签很适合显示计算机代码:</p>56 57 <pre class="brush:php;toolbar:false">58 for i = 1 to 1059      print i60 next i61

2、始终为属性值加引号

属性值应该始终被包括在引号内。双引号是最常用的,不过使用单引号也没有问题。

在某些个别的情况下,比如属性值本身就含有双引号,那么您必须使用单引号

3、h标签只用于标题

请确保将 HTML heading 标签只用于标题。不要仅仅是为了产生粗体或大号的文本而使用标题。

搜索引擎使用标题为您的网页的结构和内容编制索引。

4、HTML 折行

如果您希望在不产生一个新段落的情况下进行换行(新行),请使用
标签

5、
还是

您也许发现

很相似。

在 XHTML、XML 以及未来的 HTML 版本中,不允许使用没有结束标签(闭合标签)的 HTML 元素。

即使
在所有浏览器中的显示都没有问题,使用
也是更长远的保障

6、计算机输出标签

 1 <br /> 2 <code>Computer code </code> 3 <br /> 4 <kbd>Keyboard input </kbd> 5 <br /> 6 <tt>Teletype text </tt> 7 <br /> 8 <samp>Sample text</samp> 9 <br />10 <var>Computer variable</var>11 <br />

8、文字方向

<p>如果您的浏览器支持 bi-directional override (bdo),下一行会从右向左输出 (rtl);</p><bdo dir="rtl">Here is some Hebrew text</bdo>

9、块引用

 1 这是长的引用: 2 <blockquote> 3 这是长的引用。这是长的引用。这是长的引用。这是长的引用。这是长的引用。这是长的引用。这是长的引用。这是长的引用。这是长的引用。这是长的引用。这是长的引用。 4 </blockquote> 5  6 这是短的引用: 7 <q> 8 这是短的引用。 9 </q>10 11 <p>12 使用 blockquote 元素的话,浏览器会插入换行和外边距,而 q 元素不会有任何特殊的呈现。13 </p>
