Adding comments to CSS is simple, and all text messages placed between the / * and * / delimiters are called comments.

CSS has only one kind of comment, whether multiline comment or single-line comment, must start with / * and end with * /, with comments in the middle.

Any character contained between the / * and * / symbols is ignored as comment text.

[example 1] comments are placed outside the stylesheet.

/ * define the header style of the web page * / .head {width:960px;} / * define the bottom style of the web page * / .footer {width:960px;}

[example 2] comments are placed inside the stylesheet.

P {color: # ff7000; / * font color setting * / height:30px; / * paragraph height setting * /}
