DIV layers and iframe. With cookies and works on all devices

We need a simple div layer that loads one topframe div layer and one bottomframe div layer with an iframe loading an external url. |--------------------------------------------------| | ENTER! | <-- 40px height, 100% width |--------------------------------------------------| | | | | | External Page | | Loads within this div | <-- 100% width, 100% height | | | | |_______________________________| When someone clicks within the topframe then the underlaying div, topframe div and the bottomframe div closes and it is saved into a cookie. If visitor comes back within x minutes then these layers isnt visible. If visitor comes back after x minutes has passed the divs are shown again. If you know a better way to achieve the above we are listening... Perhaps only two divs is needed? IMPORTANT! This div's should be closed after ONE click in the topframe and it should work on ALL devices (desktop, mobile, tablet etc.) This should be an easy task for anyone experienced in html and javascript so please bid fair. Full payment when I'm happy with the results. Milestone is ok.
