Make big changes to your Joomla site & template with custom code
If you want to insert custom code: JavaScript, PHP, HTML or CSS code (including banners or text ads like Google Adsense) in Modules or directly in the template (header/body) you have to use additional extension(s) for Joomla 2.5 or Joomla 3. Some of them can also display random HTML-code in the content of your website.
