Could someone help with the html for the SWRPG Force Die symbol in GM Binder, where half is white and the other is black. I have created the force die symbol using the following code, thanks!

}

.phb .proficiency {

font-family: 'EotE Symbol';

color: #FEF035;

text-shadow: -1px 0 #000000, 0 1px #000000, 1px 0 #000000, 0 -1px #000000;

}
