HTML语言代码大全

HTML，全称为超文本标记语言（HyperText Markup Language），作为构建网页内容的核心语言，一直以来在Web开发中占据重要地位。HTML通过标签和元素来定义网页的结构与内容，为浏览器解析和渲染页面提供了标准化的规范。在这篇文章中，我们将探讨一些常用和必备的HTML代码，帮助初学者快速上手，同时也为有经验的开发者提供参考。

基本结构

任何HTML文档都应遵循特定的基本结构，包括声明文档类型、标签以及其中的和部分。




    
    
    页面标题


    欢迎来到我的网页
    这是一个段落。

声明文档类型，确保浏览器以标准模式渲染页面。
标签包裹整个网页内容，lang属性用于指定网页内容的主要语言。
部分包含元数据，如字符集声明（）、视口设置（）以及标题（</code>）。</li> <li><code><body></code> 部分定义了网页的所有可见内容，如标题（<code><h1></code>）、段落（<code><p></code>）等。</li> </ul> <h2>常用元素</h2> <h3>标题</h3> <p>HTML提供了从<code><h1></code>到<code><h6></code>六个级别的标题，<code><h1></code>为最高级标题，<code><h6></code>为最低级。 </p><img src='https://cb2.cn/plugins/addons/wxinseo/template/picture/ad9f87e3fc46d59d4bcf706b5f96f206.jpg' alt='html语言代码大全' /> <pre><code class="language-html"><h1>一级标题</h1> <h2>二级标题</h2> <h3>三级标题</h3> ...</code></pre> <h3>段落与换行</h3> <p>段落使用<code><p></code>标签包裹，换行可以通过<code><br></code>标签实现。 </p> <pre><code class="language-html"><p>这是一个段落。</p> <p>这是另一个段落。</p> <p>这里有一个<br>换行。</p></code></pre> <h3>超链接</h3> <p>使用<code><a></code>标签创建超链接，通过<code>href</code>属性指定链接的目标地址。 </p> <pre><code class="language-html"><a href="https://www.example.com">访问示例网站</a></code></pre> <h3>图片</h3> <p>使用<code><img></code>标签插入图片，<code>src</code>属性指定图片路径，<code>alt</code>属性提供替代文本。 </p> <pre><code class="language-html"><img src="image.jpg" alt="描述图片的文字"></code></pre> <h3>列表</h3> <p>HTML支持无序列表（<code><ul></code>）、有序列表（<code><ol></code>）和定义列表（<code><dl></code>）。 </p> <pre><code class="language-html"><ul> <li>无序列表项1</li> <li>无序列表项2</li> </ul> <ol> <li>有序列表项1</li> <li>有序列表项2</li> </ol></code></pre> <h3>表格</h3> <p>表格由<code><table></code>标签定义，<code><tr></code>表示行，<code><td></code>表示单元格，<code><th></code>表示表头单元格。 </p> <pre><code class="language-html"><table> <tr> <th>表头1</th> <th>表头2</th> </tr> <tr> <td>单元格1</td> <td>单元格2</td> </tr> </table></code></pre> <h2>表单</h2> <p>表单用于收集用户输入，通过<code><form></code>标签定义，包含各种输入控件如文本框（<code><input type="text"></code>）、按钮（<code><input type="button"></code>或<code><button></code>）、复选框（<code><input type="checkbox"></code>）、单选按钮（<code><input type="radio"></code>）等。 </p> <pre><code class="language-html"><form action="/submit-form" method="post"> <label for="name">姓名:</label> <input type="text" id="name" name="name"><br><br> <input type="checkbox" id="subscribe" name="subscribe" value="yes"> <label for="subscribe">订阅邮件</label><br><br> <input type="submit" value="提交"> </form></code></pre> <h2>语义化标签</h2> <p>HTML5引入了一系列语义化标签，如<code><header></code>、<code><footer></code>、<code><nav></code>、<code><article></code>、<code><section></code>等，有助于提升代码的可读性和SEO。 </p> <pre><code class="language-html"><header> <h1>网站标题</h1> <nav> <ul> <li><a href="/">首页</a></li> <li><a href="/about">关于我们</a></li> </ul> </nav> </header> <article> <h2>文章标题</h2> <p>文章内容...</p> </article> <footer> <p>版权所有 © 2023</p> </footer></code></pre> <p>HTML语言博大精深，上述仅为冰山一角。掌握HTML的基础语法与常用标签，是成为Web开发者的第一步。随着实践的深入，你将不断发现HTML的更多强大功能和灵活应用。希望本文能成为你学习HTML旅程中的一盏明灯，引领你探索更加广阔的网络世界。 </p> </div> </div> <div class="news-txtpaging"> <div
