In-depth understanding of the five key points of HTML global attributes requires specific code examples

HTML (Hypertext Markup Language) is the basic language for building web pages, and the global attributes of HTML are An attribute that can be applied to any HTML element. Global properties have broad applicability and can provide better interactivity and functionality to web pages. This article will introduce five key points for in-depth understanding of HTML global attributes and provide specific code examples.

Point 1: accesskey attribute
The accesskey attribute is used to define a keyboard shortcut that allows users to quickly access the element related to the attribute by pressing the specified key. The following is a specific example:

<button accesskey="S">保存</button>

In the above code example, when the user presses the "Alt" "S" key combination, the button will be triggered to implement the save function.

Point 2: class attribute
The class attribute is used to define the class name of an element and can be used to classify and select web page elements. Here is a concrete example:

<div class="container">
  <h1 class="title">欢迎来到我的网站</h1>
  <p class="content">这是一个示例网页</p>
</div>

In the above code example, the .container class is used to mark the <div> element as a container, and the .title class is used to mark the <code><h1></h1> elements are marked as titles, and the .content class is used to mark <p></p> elements as content.

Point 3: contenteditable attribute
The contenteditable attribute is used to specify whether an element is editable. Here is a specific example:

<div contenteditable="true">
  这是一个可编辑的区域
</div>

In the above code example, when the user clicks on the <div> element, the text content can be edited directly in the web page. <p>Point 4: draggable attribute<br>The draggable attribute is used to specify whether an element can be dragged. Here's a concrete example: </p><pre class='brush:php;toolbar:false;'>&lt;img src=&quot;image.png&quot; draggable=&quot;true&quot; alt=&quot;In-depth understanding of the five key points of HTML global attributes&quot; &gt;</pre><p>In the above code example, when the user clicks and drags the <code><img alt="In-depth understanding of the five key points of HTML global attributes" > element, it can be moved around the web page or dropped to other Location.

Point 5: hidden attribute
The hidden attribute is used to hide an element. Here is a specific example:

<p hidden>这是一个隐藏的段落</p>

In the above code example, the <p></p> element is hidden in the web page and is not displayed in the user's view.

Through the introduction of the above five points, we have an in-depth understanding of the usage and functions of HTML global attributes. These global properties can bring better interactivity and functionality to our web pages. Of course, the global attributes of HTML have many other features and applications. I hope readers can further explore and use them to improve the user experience of web pages.
