How can i add my css file to html web page?

The important points are rel, media, href. If it will go wrong then your code goes wrong.

<link rel=''stylesheet" href="css/mystyle.css" media="screen">

In the above code rel means relationship is equal to style sheet.
And the important thing is we should not give wrong path for css file. Here i have created a css folder then i have saved my 'mystyle.css' file then i am pointing that file into this html. If your style sheet will be in your main file only then no need to give any path.
