Feel free to do what you want with this Project file created using the free to download, SOURCE framework. This site is built with just 7 SOURCE stacks and no 3rd party stacks were used. The icons and images are part of the free downloads available here.
This is a SOURCE Grid demo. SOURCE used CSS Grid - simple to learn, setup and use and has a vast arrange of powerful features. Even the free SOURCE uses CSS Grid.
Note how the lower buttons line up perfectly! This is done with simple drop down selection of how stuff is spaced out.
Check out the navigation at the top. The nav links can be setup to be smooth scroll links within this page, links to other pages or external URLs. Even buttons can be added to the navigation.
The animated backgrounds are pure CSS animated gradient backgrounds. No animated GIFs used here.
The entire web code, i.e. CSS, HTML and JS including the animated backgrounds, used on this page, is less than 20Kb in size. Many RW frameworks are well over 500Kb just to create a blank empty page!
Because the code is so small, the web page will load quicker and update quicker. SOURCE is also lightening quick in edit mode.
