You click on the colored text, and it takes you to that section. To do this, you need to do two things. The first, is to make the link, and the second, is to make where the link will lead to.

There are mainly two kinds of ways to have graphics on your web page. The first, is to use a graphic that is on somebody elses' page. The second, is to upload the graphic to your own account. Personally, I perfer to use the upload method. If you are using the other way, there is always a chance that the person who made that page will decide to delete that graphic.
