In this article we are going to learn about how do we add a comment in HTML code. Let’s dive into the article for getting better understanding on adding comment in HTML code.

要在HTML代码中添加注释，请使用注释标签（!— Comment—>）。这是一种良好的编码实践，使编码人员和读者都能从理解代码的帮助中受益。理解复杂代码的步骤非常有帮助。在调试代码时，注释标签非常有用。

• It is a straightforward bit of code that web browsers wipe off (ignore), meaning they do not appear.

• Understanding the purpose of a piece of code, particularly in complex source code, is helpful to both coders and readers.

Syntax

Following is the syntax for comment in HTML

Let’s consider the following examples to get clear idea on how do we add a comment in HTML code.

单行注释

Single line comment is given inside the () tag.

Let’s look into the following example

Example

示例

In the following examples we are using the single line comment.

   
   
TutorialsPoint
   
   
The Best E-Way Learning

当脚本执行时，它将生成一个输出，在网页上显示没有注释的文本。

Multi-line Comment

The syntax (!- ->) can be used to specify several lines. In essence, it is the same as the syntax for single-line comments; the only difference is that the first half of the comment ("->") is appended when the intended comment line ends.

Example

示例

Considering the following example, where we are using the multi line comment tag.

   
      
      
MSD
      
      
The Best Finisher
   

运行上述脚本后，它将在网页上生成包含脚本中使用的文本的输出。

使用标签

An HTML "comment" tag once existed, but none of the current browsers support it.

Example

示例

查看下面的示例，我们正在使用标签。

   
      Heading tag
      
DUCATI
      Paragraph tag
      
The Fastest Bike
   
 

When the script gets executed, it will generate an output displaying the text used in the code on the webpage along with the comments used by tag as modern browsers won’t support it.
