Calling Activewidgets Grid CSS experts

Ive got a 5x5 grid that contains edit boxes in each cell.
I'm developing for both mozilla and IE however in both cases the grids usability form an editing viewpoint isnt great. I understand editing hasnt been implemented by yourselves yet and therefore there probably isnt any css rules to handle this.
However if any one could help out a css novice with changing the usability of the screen to have flashing cursor, tabbing, highlighting with different colour for both mozilla and IE it would be great.

thanks..
