I have a question about setting the font size of text on a web page. When I set a font at "1.65em," for example, it appears at an appropriate size in Visual Studio's design view, but when I preview the page, the font appears significantly smaller. When I use "165%" essentially I get the same results -- it looks right in design view but too small when previewed. Also, regardless of what em or % I use, the font size changes very little compared to the changes I see in design view. The difference in font size between design and preview mode makes using em or % relatively useless. I don't understand why this is. When I use pixels as the unit of measurement design view is very close to the preview. Is there a breif explanation of this phenomenon?
