hai
I am new one in website designing work so i dont know what type of font we can use in website? so please explain me anyone

Use fonts pre-installed on your pc :
- Arial
- Verdana
- Gerogia
- Times new roman
- Trebuchet
- Impact

Or you can check for "web fonts" (free ones like http://www.google.com/webfonts) try to google this to find how to use it

And also check this out for more information : http://www.w3schools.com/cssref/css3_pr_font-face_rule.asp

Please do not use Comic Sans or Papyrus.

Apple Casual, however, is allowed ...

i did not quote these... they are forbidden, their use is punished by death in some countries

yes try http://www.google.com/webfonts very cool

As vinz said, you can use any font by using the css3 @fontface, as long as you respect the font license (regarding the embedding)
