This will be a tricky one.

You should set every ".products-grid .product-cell" to "position:relative", and ".products-grid .product-cell .product" to be "position:absolute". But this will collapse the ".product-cell" (as absolutely positioned blocks are taken out of the flow), so now you have to set a fixed width and height for ".product-cell" (and also tweak the nested ".product" blocks to correct their dimensions).

So, basically it is possible without JavaScript, but you will end up with fixed dimensions set for the cells.
