Most pages will have both absolute and relative links. The relative links link a page within one Web site to another page within the same site.
Relative link URLs have only the name of the file and any "path" information needed for the browser to find the page. So, for example, if I wanted to link to another page in the same folder as this page, the relative link would look like this:
Another page in the same folder
If I want to link to another page in the same general folder that's located in a subfolder called "spring," the relative link would look like this:
Another page in a subfolder
On the other hand, if this page were located in a subfolder and I wanted to link to a page in the main folder, it would look like this:
Another page in the main folder
