problems with :hover and google maps iframe on explorer 11

[lugi]

Hi,In the page of my site i used a layout made of boxes (with flexbox). In the 2nd box I embedded a google maps with iframe and i covered the map with a div white with some words on it. with :hover I caused the white div to not display when I mouse over it. This works pretty good whith firefox and chrome but not with explorer, how can I fix this problem?Thank you
