Without tables, your labels and entry fields will zig zag all down the page, making it look unprofessional and sloppy. Be consistent when choosing the font for your website. Make sure your entire page uses the same or similar fonts. There should be a pretty good reason for choosing a different font for separate pages on your site. Smaller fonts will probably work best for most of the content on the site.
Larger fonts are more appropriate for headings.
Whatever you do, avoid overusing ALL CAPS to grab the attention of your visitors. Remember, keep it simple for a professional, clean looking site. The more professional your site looks, the more comfortable your customers will be purchasing from you. All rights reserved.
