Show Information on Block Hover

Hi,
Unfortunately our theme has no such option. Our blocks were not designed to show extra information on hover.
You can add the bottom gradient in big grids if you chose a different style for the block: http://screencast.com/t/doqorJXJa
You can activate it with css on other blocks that use the title on top of the image:

.td_module_mx1 .td-module-meta-info, .td_module_mx8 .td-module-meta-info, .td_module_mx1 .td-module-meta-info{
background-color: rgba(0, 0, 0, 0.25);
}

Add the code in the theme panel->custom css box.
Thank you!
