(1) Leave links underlined. You can remove underlines from your links by modifying the text-decoration property in CSS, but it's advisable to leave the underline on your links. Underlined text is almost universally understood to be a clickable link, and using underlines will make your site more user-friendly.
(2) Differentiate between visited and unvisited links. Creating different styles for visited and unvisited links helps visitors keep track of which areas of the site they have visited. In general, it's best to create styles that make unvisited links more noticeable and visited links less so. This can be accomplished by using a brighter color for unvisited links and a more subtle or less saturated color for visited links.
(3) Experiment with hover styles and colors. Creating a slightly more dramatic style for the hover state is an effective way to provide feedback to visitors that the link is indeed clickable. For example, you can add a background color for the hover state so the link appears to be highlighted, or use an overline to add emphasis. Feel free to use link colors that coordinate with your design; however, avoid purple to indicate normal links and blue to indicate visited links, since this reverses the normal color conventions and could confuse visitors.
(4) Create link pseudo-class styles in the correct order. In a Web page, link pseudo-class styles are applied according to the order in which they are listed in the style sheet. Expression Web writes style rules in the style sheet in the order in which you create them, so always create your styles rules in this order: a:link, a:visited, a:hover, and a:active. A popular way to remember this order is to think of the phrase LoVe--HA (Link, Visited, Hover, Active).

(Peter Minuit Problem) Legend has it that, in 1626, Peter Minuit purchased Manhattan Island for $24.00 in barter. Did he make a good investment? To answer this question, modify the compound interest program of Fig. 4.6 to begin with a principal of $24.00 and to calculate the amount of interest on deposit if that money had been kept on deposit until this year (e.g., 384 years through 2010). Place the for loop that performs the compound interest calculation in an outer for loop that varies the interest rate from 5% to 10% to observe the wonders of compound interest.
