In a Category card, i'd like to edit the font-size and font color for each card. The ability to change the appearance of the Category icon already exists, e.g. you can select the color of the icon. i'd like the ability to change the font color to match the icon color and the customize the font size.
Currently i am customizing the font on Category cards by adding on to an existing esri class in a text card on my page.
.panel-footer {
font-size:18px;
color: #16a8b5;
} i suspect that approach (adding to base Hub classes) is not a recommended tact. Additionally it forces all category cards to have the same color and size. I can imagine a scenario where each Category card might have its own color and font size.
