Introduction to CSS

Imagine you've just designed a two hundred page web site for a client (or maybe for yourself) but at the last minute your client (or you) decide the font is a little two small or the typeface should be serif instead of sans-serif? You didn't know how to use cascading style sheets (CSS) so you coded all of the pages with the old-style <font> tag. If you didn't know CSS, chances are you'd have to replace every occurrence of the old <font> tag with the new <font> tag. But if you had decided to write the site with CSS from the get-go, all you would have to do is replace one single line of code in a master file, and your entire site would be rendered immediately in your new style.

That's just one file to upload. That's a lot better than two hundred. Now you can do other things with your time. This is one major reason cascading style sheets are important. CSS makes web site maintenance easier.
 CSS LINKS

a:link { } - regular link
a:visited { } - regular link already visited
a:hover { } - any link with the mouse cursor currently over it
a:active { } - the split-second a link is clicked

CSS listes 

OL { list-style-type: upper-roman; }
OL OL { list-style-type: upper-alpha; }
OL OL OL { list-style-type: decimal; }
OL OL OL OL { list-style-type: lower-alpha; }
OL OL OL OL OL { list-style-type: lower-roman; }
colors :

body { background-image: url(graphic.jpg);
color: #FFFFFF; background-color: #000000;
background-repeat: no-repeat; }
CSS CLASS 


p.first{ color: blue; }

p.second{ color: red; }

  <html>

<body>

<p>This is a normal paragraph.</p>



<p class="first">This is a paragraph that uses the p.first CSS code!</p>

<p class="second">This is a paragraph that uses the p.second CSS code!</p>


out put :

 This is a normal paragraph.

This is a paragraph that uses the p.first CSS code!

This is a paragraph that uses the p.second CSS code!

h4 { color: red; }
