Front end magic / Advanced HTMLS 5

Hi everyone

I would like to enhance an outsystems project with a layout design that looks / works something like this:

Essentially when one hovers over a panel it triggers certain webblcks to appear and slightly changes its nature i.e. a textbox becomes available when you hover over it.

Thank you

and what is your problem/challenge exactly?

it can all be done with css3 en possible jquery.
