Comments are very useful in HTML. Comments can be used to explain code and remind yourself or other developers about what to do next.

Comments in HTML are defined using comment tags. This mark is a less than sign "". Content marked with comments will not be displayed by the browser. This means you can add comments in your HTML code to improve the readability and maintainability of your code.

Here is an example:

<!-- 这是一个HTML注释 -->

Copy after login

In the above example, the content in the comment tag is "This is an HTML comment". This is a simple example, but you can use comments in your actual HTML code.

For example, you can add comments in the HTML to describe your code:

<!DOCTYPE html>
<html>
<head>
    <title>我的网页</title>
</head>
<body>
    <!-- 这是头部区域 -->
    <header>
        <h1>欢迎访问我的网页</h1>
        <nav>
            <ul>
                <li><a href="#">主页</a></li>
                <li><a href="#">关于我们</a></li>
                <li><a href="#">联系我们</a></li>
            </ul>
        </nav>
    </header>

    <!-- 这是内容区域 -->
    <main>
        <p>这是我的网页的内容区域。</p>
    </main>

    <!-- 这是页脚区域 -->
    <footer>
        <p>版权所有 © 2021 我的网页。</p>
    </footer>
</body>
</html>

Copy after login

In the above example, the comment tags explain the header area, content area, and footer area of the web page . These comments help other developers better understand the code and maintain it.

In addition to adding comments in HTML code, you can also add comments using an HTML editor. For example, in Dreamweaver, you can add comments by following these steps:

Select the code you want to comment.
Click the "Comment" option in the "Insert" menu.
Enter your comments in the pop-up dialog box.
Click the "OK" button.

This will add a comment marker to the code, along with the comment you entered.

In summary, it is a good practice to add comments in your HTML code. It improves code readability and maintainability, making your code easier to understand and modify. If you're a team developer, comments can help your colleagues better understand your code and collaborate.
