HTML comments, we often have to do some HTML comments next to some code, this has many advantages, such as: easy to find, easy to compare, convenient for other programmers in the project team to understand your code, and it is convenient for you to understand and modify your own code in the future.

HTML comment syntax

Let's sort out a more comprehensive one for you.

1 、

2. / / comment content (insert a single-line comment in css or javascript)

3. / * comment content * / (insert multiline comments in css or javascript)

JavaScript comment

JavaScript comment syntax

/ / comment content / * comment content * /

CSS comment

As described in the HTML tutorial, comments also play an important role in CSS documents, which can help us remember the meaning of CSS, where to load in HTML documents, and so on.

Start with / * and end with * / for CSS comments

CSS comment syntax

Copy the code

The code is as follows:

/ * comment content * / example / *-start of text style-* / / * White 12-pixel text * / .dreamduwhite12px {color:white;font-size:12px;} / * Black 16-pixel text * / .dreamdublack16px {color:black;font-size:16px;} / *-end of text style-* /

Example of JavaScript comment

Use two double diagonal bars to explain the line

[code]

/ / [xss_clean] ("www.jb51.net")

Annotate code blocks with diagonal stars (multilines)

/ *

Varjb51= "www.jb51.net"

Varjb51= "du"

* /

[html]

Tip: too many JavaScript comments will slow down the execution and loading speed of JavaScript, so you should remove JavaScript comments when publishing a website.

Tip: comment block (/ *... * /) can not have (/ * or * /, JavaScript regular expression may produce this kind of code), this will produce syntax errors, so I recommend you to use / / as the comment code, this tutorial will all use / / mark comments.
