Source Elements is a RW8 project file that contains over 50 pre-built web components using only stacks from Source and the Source Addon pack. These are ready to be dropped into any Source project and can be easily adapted to suit your project (there are notes in the project file to assist with this).
You can preview the components using the links below. It is important to note that the categories used here are just to group them in some way. Any component could be repurposed for any use.
