/*...*/and//Comment tags

Examples are as follows:
/* Comment content */
Example
/* Start--------------------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----------*/

JavaScript uses two double slash comment lines

document.write ("Www.jb51.net"); Use the slash star Comment code block (multiple lines)

/*
var jb51 = "Www.jb51.net";
var jb51 = "Du";
*/Tip: Too many JavaScript annotations can slow down JavaScript execution and loading speed, so you should remove JavaScript comments when publishing your Web site.
It is not possible to have (/* or */,javascript in a regular expression) in the comment block (/*), which produces a syntax error, so I recommend that you use//as the comment code.
