With the LoginSecure Smooth Scroll extension, you can stop anchor links from directly going to your assigned area but instead, allow a smooth scrolling effect that will not only please your visitors but it will also look a lot better.
Extension features are:
Smooth Scroll
Smooth Scroll will tie all your internal links to a handler that
will produce a smooth scroll to their target instead of an instant
jump.
This works in Firefox, Chrome, Edge, IE10, Opera, and Safari.
Unsupported browsers would just use normal internal link
behavior.
Joomla Module Functionality
An extension like this is generally expected to be a plugin. But
we decided to make it a module instead.
Therefore it can be added anywhere you want with Joomla's
{loadposition} syntax.
Or set the position as debug and assign to specific menu items.
