HTML 知识点汇总第一章HTML 基础知识1、HTML 简介HTML(Hypertext Markup Language) ，超文本标记语言，HTML 利用各种标记来标识文档的结构以及标识超链接的信息。它是从 SGML(Standard Generalized Markup Language，标准通用标识语言)中的一个子集演变而来的。2、HTML 的标记组成HTML 用于描述功能的符号称为“标记”。标记在使用时必须用尖括号“<>”括起来，而且是成对出现的，无斜杠的标记表示该标记的作用开始，有斜杠的标记表示该标记的作用结束。如、

、
等。2) 双标记：双标记有头有尾，且前面的标记与后面的标记保持一致，但在后面的标记前有斜线，语法形如：<标记>内容。例如：
段落
3) XHTML 要求所有标记均为小写，且所有标记属性必须添加双引号4) 标记对不能交叉3、HTML 基本结构
网页标题1)
标记对不能放在<body>标记对中，同理，其它表示内容的标记也不能放在<head>标记对中2) <html></html>表示 HTML 语言，在<html></html>里面包含头部(<head></head>)和内容体(<body></body>)。3) HTML 注释表示为<!--注释内容-->第二章文字与图像1、设置文字字体、大小与颜色语法：<font face=”宋体” size=”1” color=”red”>文字</font>1) 设置文字的字体、大小、颜色需要使用<font>标签2) Face 属性设置文字字体，多种字体用逗号隔开3) Size 属性设置文字大小4) Color 属性设置文字颜色，参数值可以是 RGB 颜色值，如#000000，也可以用颜色的单词表示，如 red2、设置正文的标题语法：<h#>主题文字</h#>，其中“#”代表数字 1-6 中的任意一个，从数字 1 到数字 6，标题大小排列由大到小(数字越大，标题字号就越小)。3、设置段落语法：<p>这里表示段落</p>4、强制换行与不换行1) 强制换行：<br />2) 强制不换行：<nobr />5、字体标记1) 物理字体<b>…</b><u>…</u>设置成粗体增加下划线<i>…</i><s>…</s>设置成斜体增加删除线设置成下标字体<sup>…</sup><tt>…</tt>2) 逻辑字体<em>…</em><code>…</code><kbd>…</kbd>设置成上标字体<sub>…</sub>设置成打字机字体强调文字...</div></div><div class="pre-detail-bottom"><a class="pre-detail-more" href="javascript:;" kes-height="0">查看更多 <i class="icon-lower"></i></a></div></div></div><div class="noticeidtxt"><p>1、当您付费下载文档后，您只拥有了使用权限，并不意味着购买了版权，文档只能用于自身使用，不得用于其他商业用途（如 [转卖]进行直接盈利或[编辑后售卖]进行间接盈利）。<br>2、本站所有内容均由合作方或网友上传，本站不对文档的完整性、权威性及其观点立场正确性做任何保证或承诺！文档内容仅供研究参考，付费前请自行鉴别。<br>3、如文档内容存在违规，或者侵犯商业秘密、侵犯著作权等，请点击“违规举报”。</p></div><div class="noticeidtxt"><p>碎片内容</p></div></div><div class="view-hd"><div class="container"><div class="view-hd-bd"><div class="format"><i class="file-icon icon-pdf"></i></div><h2>前端基础HTML知识点汇总</h2><ul class="operate"><li><a class=" view-down-btn" href="javascript:;" onclick="down.init()" title="下载前端基础HTML知识点汇总"><i class="iconfont icon-xiazai"></i><span>下载文档</span></a></li><li><a id="close-preview" class="btn btn-close" href="javascript:;" title="关闭预览"><i class="iconfont iconclose"></i><span>关闭预览</span></a></li></ul></div></div></div><script>var _preview_param = {
