RapidWeaver Stacks add-on info:
Do you sometimes need to center content vertically and or horizontally? Or position top, bottom, left, right? If you do, then the Stack Me Stack is for you.

With the Stack Me Stack you can organise an entire page – 'stadking' stacks, entering content. You'd be amazed how easy it is!

Update 3.0.4: Option to 'crop' image below breakpoint. This allows you to have an 2560 px wide image and let the Stack Me Stack crop the images on both sides until breakpoint is reached – then let the image scale down with the size of the browser window (tablet / smartphone).

Scroll down to see a demo of the Stack Me Stack.

Special features:
The Stack Me Stack adds a few extra very nice to have options. Add background, text, link and hover color – override the choices of your theme. Define the height depending on the users browser window – but override when breakpoint is reached (responsive settings).

Bonus-feature: Option to 'fix' an image for a simple parallax effect.
