"Grow Effect" inserts a style block with the special class name: grow-effect to apply a grow effect to the form's elements (input tags, buttons, etc.) in mouse-over, focus, and active states.
Assigning the class name to the form's elements:
[submit class:grow-effect "Button"]
* The "Free" blocks are accessible from the plugin, even if it has not been registered, or the license has expired.
