Displaying a section of a html page when a user clicks on the internal link

[Reidinc]

i am trying to make it easier to navigate an html page that i have created. The links at the begining of the page serve a section jumps. Now i want to hide the DIV contents and remain with the internal links only when someone loads the page, then when the user clicks on an internal link, only the content assosiated with the DIV should be shown to the user. Which scripts should i use? I also want to include a button that can allow the use to close/hide the content after they finish reading the displayed section and be taken to the main page with internal links.\[code\]<h3>Antithyroid Drugs</h3> <ul> <li><a href="http://stackoverflow.com/questions/15499833/#thioamides">Thioamides</a></li> <li><a href="http://stackoverflow.com/questions/15499833/#iodine_salts">Iodide Salts and Iodine</a></li> <li><a href="http://stackoverflow.com/questions/15499833/#radioactive_iodine">Radioactive Iodine</a></li> <li><a href="http://stackoverflow.com/questions/15499833/#anion_inhibitors">Anion Inhibitors</a></li> <li><a href="http://stackoverflow.com/questions/15499833/#others">Other Drugs</a></li> </ul> <div id="thioamides"> Thioamides Methimazole and propylthiouracil (PTU) are small sulfur-containing thioamides that inhibit thyroid hormone synthesis by blocking peroxidase-catalyzed reactions, iodination of the tyrosine residues of thyroglobulin, and coupling of DIT and MIT (Figure 38
