Recently, I encountered an issue with a ul list where the hidden answers would be revealed using jQuery. However, one li element kept shifting out of position every time I clicked on a list item.
This problem seemed to arise after I added a red A and ensured that all answer divs were the same height by floating them left and assigning percentage widths.
I suspect there might be something wrong in my CSS causing the divs to have different heights, but I'm not entirely sure what it could be.
