This time I will bring you how to use horizontal line annotations and code comments in HTML. What are the precautions for using horizontal line annotations and code comments in HTML? The following are Let’s take a look at practical cases.

Horizontal line

Use the

tag to draw a horizontal dividing line at the current location.
Example

<p>主要内容</p>  
<hr />  
<p>底部内容</p>

Horizontal lines can effectively isolate different content parts and give people a sense of hierarchy.

Tips:
Since the borders of DIV or other block elements can be formatted and displayed through CSS, many times the width of the border of the block element is set to achieve the effect of a horizontal line, but tag still cannot be completely replaced.

HTML Comment

The XHTML comment tag is a special tag. As the name suggests, it is used to comment on the content in the XHTML document. Of course, it will not be displayed in the browser. The comment tags are as follows:

<!—这个地方写注释内容-->  
一个例子：   
<p id="nav"><!--nav start-->

Note:

There is an exclamation mark after the opening left bracket. In addition, do not write comments in other languages such as "//" or "/*".
Tips:
It is a good habit to add comments appropriately and can be used wherever you want to comment, so that the
html document we write is easy to read and maintain.
