从零开始的html教程(2)：了解基本的标签与元素

作者：袖梨 2022-06-25

一、html中的标签

上一课利用dreamweaver自动生成的页面的代码为：

无标题文档

“”””像这样方括号里框着英文与符号的玩意就叫做”标签”，又叫标记标签。

Html是由一堆标签组成的超文本标记语言。以上代码一共9个标签。

标签总是成对出现的，其中第一个字符为英文字母的标签叫开始标签，在同样的英文前加了”/”斜杠符号的叫结束标签。

二、html中的元素

开始标签与结束标签的本体与之间的内容叫元素。上节课生成的代码中，“无标题文档”是一个元素，有着开始标签与结束标签，标签之间的”无标题文档”是这个元素的文本。

元素中是可以嵌套其他的元素的。比如上述例子中，””元素中嵌套了”,,,”这四个子元素，””是它们的父元素，因为它们都被包在（嵌套在）””元素中。

三、上述例子中的标签都是什么意思呢？

这个比较特别，不是html的标签。是用来声明文档类型的，必须要放在标签的前面。如果不用声明的话，浏览器会用”怪异模式(quirks mode)”进行渲染。

用来定义文档的开头与结尾，可以理解成之间就是一个网页。

顾名思义，就是网页的头部，可以修改网页的标题、添加css样式表和加载javascript脚本。

src="https://img.111cn.net/uploads/20220923/img_632d681f72cc433.png" alt="" /></a></p><p> 网页上的标题就是的内容。</p><p><strong>5.<body></strong></p><p> 网页的主题，网页上用户可视的内容基本都是在这里添加修改。大家想在网页里添加一段文字的话，就得写在里。</p><p><strong>6.<meta></strong></p><p> 这里定义了网页使用UTF-8编码，用在元素里。（标签现在了解就够了）</p><p><span style="color:#E53333;font-size:14px;"><strong>四、如何在自己的网页里加入几段文字呢？</strong></span></p><p> 在这里介绍一个新的标签――<p>标签。</p><p> <P>是段落标签，每个<P>元素为一个段落，即使<p>元素中出现转行，浏览器中也只会显示出空格。</p><p> 不同的<P>元素之间自动空行。</p><p><strong>举个例子：</strong></p><p><strong>1.中间空了一个字符</strong></p><p><a href="https://img.111cn.net/uploads/20220923/img_632d681f9368634.png" class="js-smartPhoto-pc" target="_blank"><img src="https://img.111cn.net/uploads/20220923/img_632d681f9368634.png" alt="" /></a></p><p><strong>2.第一个后面回车键转行</strong></p><p><a href="https://img.111cn.net/uploads/20220923/img_632d681fc445435.png" class="js-smartPhoto-pc" target="_blank"><img src="https://img.111cn.net/uploads/20220923/img_632d681fc445435.png" alt="" /></a></p><p><strong>3.将“段落”放入新的</strong><strong>标签</strong></p><p><a href="https://img.111cn.net/uploads/20220923/img_632d681ff0bbb36.png" class="js-smartPhoto-pc" target="_blank"><img src="https://img.111cn.net/uploads/20220923/img_632d681ff0bbb36.png" alt="" /></a></p><p> <p>元素内不管输入多少空格或者转行，显示出来的结果都始终在同一行里；而将想要另起一行的文字标上<p>标签就会实现自动转行。</p><p><span style="font-size:14px;color:#E53333;"><strong>五、试着随便编辑几段文字并预览一下网站的效果吧！</strong></span></p><p> 点击软件右下角的图片上标记的图标可以实时预览网页的效果。</p><p><a href="https://img.111cn.net/uploads/20220923/img_632d682029ab437.png" class="js-smartPhoto-pc" target="_blank"><img src="https://img.111cn.net/uploads/20220923/img_632d682029ab437.png" alt="" /></a></p><p> 以上就是本次教程的内容了，简单介绍了下html里基本的定义和标签，并且能做出有简单文字的网页了。下次教程将教大家几个常用的标签来充实网站的内容！</p> </div> </div> </section> <section class="wrap-box"> <div class="g-tit"> <h2>相关文章</h2> </div> <ul
