I'm trying to display 9 square images in a 3x3 grid. I'd like to be able to stretch the bounding box of the overall 3x3 square, thus stretching each of the tiles. 

My solution would involve tables - I suppose that's shunned upon nowadays? What would be the right way to do this among modern and current-generation browsers?

Please be kind - the last time I did frontend dev, tables were in fashion and it wasn't quite Y2K.
