Can i use it on whatever template i need?
Yes, Visual Styles Modules will work on every template if it complies with Joomla! framework or standard modules rendering.
The more complex is the template you are using and the more useful will be using Visual Template Studio on your site. An operation that could require several minutes can be completed in just few seconds dragging elements exactly where you need.
If you are unsure about your template and possible results that you can get using Visual Styles Modules, contact us for a free trial package. Some limitation may arise using YooTheme templates due to the proprietary templating engine used.
