Great trick indeed as I am a big fan of Noun Project icons (actually the $35 yearly plan for unlimited icons in SVG format is a sweet added value to any app project).
I am just stuck with the implementation of your tip: I save the icon and HTML code as a text attribute in my option sets, then I select this icon’s attribute as dynamic data in my HTML element on my page. But the icon doesn’t appear. However if I simply copy paste the HTML code in my element then the icon appears alright. And then second question, how do you do to change the style/color of the icon? In the HTML style we can only change padding, shadow and border style, but what about the color of the icon?
Hope you can detail a bit more this part for me!
