I could be doing something wrong, but for our dev site, I set up the html and css in a text editor, make sure everything works, and then copy over to the HUB site to test.
Any .svg I attempt to use with the <svg> tag doesn't seem to work when copied over to the hub text editor.
Are these just not supported yet? and if not, are they currently on the horizon for support?
Coming this.......Thursday 🙂
Awesome news!
Why can't you host the .SVG files in ArcGIS Online and then use then for categories in ArcGIS Hub?
