We have a form which shows rendering issues in Mozilla. We tried to increase the Checkbox Size and this is how a form renders in Mozilla: http://prntscr.com/jp6yv2 which is not correct. And, this is how a Form renders on Chrome http://prntscr.com/jp72h0 which is correct actually as you can see Checkbox Size Changes are showing up which are not taking effect in Mozilla. A Solution and thoughts on the issue are welcome.
Here is the code snippet which I am using
@media screen and (min-width: 1200px)
.ult-open ul.gfield_checkbox li.gchoice_1_3_1 input[type="checkbox"] {
width: 20px!important;
height: 20px!important;
}
