A back link is a link that moves the browser backwards one page, as if the user had clicked the Back button available in most browsers. Back links use JavaScript. For example, the following link moves the browser back one page if your browser supports JavaScript (which it does) and if it supports the window.history object, which is necessary for back links: Go Back

For example on this webpage you might have noticed the "Back" button which brings you back to the previously loaded webpage.

Actually, most browsers already have this button, but you can make your own "link" for this purpose as well.

Copy the following code into your page in code view:

<a href="javascript:javascript:history.go(-1)">Click here to go back to previous page</a>

Which will work like this:
Click here to go back to previous page
