In the previous lesson you learned that a web address (URL) consists of various parts. You also created a link in your portfolio home page to your school's home page. This link used an absolute address (the full address to the school website). Now you will learn to make links to pages within your own website, using a relative address.
A relative address is one that refers only to a portion of the web address, rather than to the full address. For example, assume you are webmaster of the domain mydomain.com, and want to add a link from http://www.mydomain.com/file1.htm to http://www.mydomain.com/file2.htm. In file1.htm, you don't need to link to the full address. You can simply link to the file name (file2.htm), since both files are located in the same place.
A relative address is an address that is relative to the location of the linking file.
At the completion of this exercise:
<a href="unit4.htm">Unit Four: Graphics</a>
Note that the destination path ("unit4.htm") gives the browser directions starting from the current folder. This type of link is called a relative address because the entire address is relative to the location of the current file. Since index.htm and unit4.htm both exist in the same folder, there is no need to spell out an entire URL. If you had saved unit4.htm in a subfolder (for example, the "unit4" subfolder, you could still link to this file using a relative address; you would just need to include the subfolder in the address, like this: unit4/unit4.htm.
After you have saved the changes to index.htm, open the file in your browser. Refresh your browser and test the link. Show your instructor your results before starting Lesson 3.
