Creating an HTML back button
Adding the code below will direct a visitor back to the page they used to open your page. For example, this is a great feature to add to any error page to help get the visitor back to a working page.
Copy and paste the below source code to add this button to your web page or blog.
<FORM><INPUT Type="button" VALUE="Back" onClick="history.go(-1);return true;"></FORM>
In the above code the -1 tells the browser to go back one page.
Note: If the page has no previous page, e.g. it was opened in a new tab, this button does nothing.
