HTML常用代码大全

HTML（超文本标记语言）是用于创建网页的基础语言，由一系列的元素组成，这些元素可以用来封装不同部分的内容，使其以特定方式显示或工作。在开发网页的过程中，掌握一些常用的HTML代码可以提高开发效率和页面结构设计的灵活性。以下是HTML常用代码的概览。

基本结构

每个HTML文档都应该包含DOCTYPE声明、html根元素，以及head和body元素。

• DOCTYPE：定义文桟的类型，确保浏览器以正确的方式渲染页面。
• html：根元素，包含了整个页面的内容。
• head：包含了页面的元信息，如标题、字符集声明、CSS和JavaScript链接等。
• body：包含了页面的实际内容，例如文本、图片、链接等。

常用标签

标题

HTML提供了六个级别的标题标签，分别为h1至h6。

一级标题
二级标题

段落

使用

标签来创建段落。

这是一个段落。

链接

链接是通过标签创建的，href属性用于指定链接的目标地址。

访问示例网站

图片

使用标签来插入图片，src属性指定图片路径，alt提供图片的替代文本，当图片无法显示时，替代文本将被显示。

列表

HTML支持有序列表

和无序列表
，列表项使用
• 标签。

  无序列表：

  
    
  项目一
    
  项目二
  

  有序列表：

  
    
  第一项
    
  第二项
  

  表格

  使用标签创建表格，通过定义行，

  定义单元格，

  定义表头单元格。 标题1 标题2 数据1 数据2 表单 表单 用于收集用户输入，可以使用各种控件，如输入框、文本区域</code>、按钮<code><button></code>等。 </p> <pre><code class="language-html"><form> <label>用户名：</label> <input type="text" placeholder="输入用户名"> <br> <input type="submit" value="提交"> </form></code></pre> <p>以上是HTML中常用的一些代码和结构。HTML语言简单易学，但其强大的表达能力使得开发者能够创造出丰富多样的网页内容。通过合理使用这些基本元素和标签，可以构建出结构清晰、内容丰富的网页界面。 </p> </div> </div> <div
