Admins can add a module to the front-end display which users can utilize to increase or decrease the size of desired text on a page.
The Zoom module for Joomla can be configured so that only certain text can be increased/decreased, so the rest of the page remains untouched and only the article meant to be read is altered.
Multiple increase/decrease button styles are included with the package.
Go to the Joomla admin section.
Select "Extensions" -> "Install/Unistall/Extensions Manager".
Upload the package's ZIP archive file and press "Upload & Install".
Zoom is also available as a WordPress plugin as well.
