We get asked quite often which are the best fonts to display a website.
Without a doubt sans-serif fonts, the ones without all the ticks and marks on the corners of all the letters, look much sharper on LCD monitors, and are easier on the eye.
CSS 3.0 supports downloadable fonts via the @font-face variable. which gives much more flexibility at the expense of users having to download your font files first..
Until CSS 3.0 is fully supported by all browsers, websites are safest sticking to the following font families:
Legible Web Fonts
Sans-Serif Fonts
font-family: Verdana, Helvetica, sans-serif;
font-family: Arial,Helvetica,FreeSans,"Liberation Sans","Nimbus Sans L",sans-serif
font-family: Tahoma,Geneva,"DejaVu Sans Condensed",sans-serif
