You can read about fonts in the CSS spec: http://www.w3.org/TR/CSS21/fonts.html In brief, em has two uses: 1) when used with font-size, it refers to the font size of the parent font. For example: p {font-size: 1.2em;} Code (markup): means that the font used to render this paragraph will be 20% greater than the font of the parent element containing this paragraph. 2) when used with any other property, it refers to the current font-size: p {height: 1.5em} Code (markup): means that the height of the paragraph is 50% greater than the font-size of this paragraph. With regards to fonts, %'s and em's are really the same. Here's more detailed description of length units: http://www.w3.org/TR/CSS21/syndata.html#length-units The advantage of using em's or %'s is that everything is relative to a single initial font-size value (or a small set of sizes), which allows you to change font sizes easily for the entire site.

Has anyone ever tried making a font themselves. i always liked the idea of making your own unique font.
What's the point if no one else on the web can see it? That's why Verdana and Arial are so popular. Most every browser can use it.
I use Tahoma and Verdana as these fonts were designed to be easier to read on a computer screen. Studies have found that serif fonts like Times New Roman are more difficult to read on computer screens. I also use Trebuchet MS for headings sometimes as it is kinda funky. I use em's and % for specifying the font size as it adjusts nicely when the Text size of the browser is changed. ross
Arial, but I also like Tahoma and Verdana. Times New Roman is beatiful to print, but terrible to read on screen. I think a lot of us are thinking the same.
