Fonts
Sample fonts are found below.

Fonts can make your web page much more interesting and pleasing to the eye than always using the default typeface. You can also use fonts together with bold, italics, and underlining to help the user discriminate between the more important information from the less important text. However, don't lose focus of the top priority regarding fonts, which is to help make your text on screen as easy on the eye as possible.

For some related pointers, see the WebDesign section.

Below we present some of the more common, web-safe fonts provided by Windows and IE. Note that as a website designer, you are limited to those fonts available on your visitors' systems for them to see it (which I assume is your goal). Therefore, you should use fonts you are fairly certain will be installed on the viewer's computer.

Many of the fonts listed below can be downloaded for free in case you don't have them.

Windows

Times New Roman or Times is a serif (meaning with curly ends) type that is available on most Windows computers. It's similar to fonts used in newspapers and magazines. Although it´s easier to read on-screen than many other fonts, Microsoft´s free font Georgia is really a better typeface for the screen.
This is 10 point.

Arial is a sans serif face (meaning without curly ends) with a more modern look. However, it isn't necessarily easier to read on screen because it's quite narrow and can look too light in small sizes. It's also used quite a bit for official forms and can therefore look stale. For Macs, there is a similar font called Helvetica.
This is 10 point.

IE Fonts.
It's true. Some fonts come bundled with your browser. For example, IE 3 and IE 4 come with Verdana and Comic Sans.

Verdana is a sans-serif face that comes with IE. It is considered one of the easier-to-read fonts.
This is 10 point.

Comic Sans is another font that comes with IE. It is an informal, if not unprofessional font, but fun.

Other Fonts

Georgia is a serif face that is much easier to read on-screen than Times New Roman (Interesting fact: Times was designed for paper, in the 1920s!). Georgia has excellent italics that are easy to read and attractive. If you have Georgia installed, you'll see this paragraph set in it. If not, you'll see Verdana, Trebuchet, or Times New Roman.
This is Georgia in 10 point.
