We would like to change our Portal for ArcGIS 10.3.1 Homepage fonts to custom fonts that align with our companies branding and standards. I installed the fonts on the web server and correctly tagged them in a custom html updating the "Description" but the custom font is being ignored and it appears to be defaulting to Veranda. I noticed there were only 5 standard fonts available in the "Description" text editor and I wondered can you use fonts outside of that list?
Example of the html modifying the font face to a custom "Geogrotesque Md"
