Lengthier pages should be broken up into smaller linked pages. File size - To minimize download time, do not exceed 100k in the sum of all pictures and graphics appearing on a single page. Because pages load from the top down, don't design pages with large graphics or all your graphics at the top. Screen widths - Web pages can look very different depending on the size of the monitor on which they are displayed. Text alignment - Avoid centered text except for headings or titles.
Text is easiest to read when the left margin is straight.
Type size and headings - Large contrast in type sizes can be distracting. Limit headings to one or two sizes and use bold or italic styles to vary emphasis instead of varying text size. They are hard to read on most monitors. Don't put a page up until it is ready to be seen.
