Using Font Awesome icons in control add-ins

This post has been long overdue. I’ve had it in my to-do list for nearly four years now, but it always ended up in the not today category. Funny how many times I’ve implemented it already, and how many times I’ve presented this, and I never ever found a few minutes to create a demo repository and a blog to come with it. So, here we go.

Including web fonts in your control add-ins is no rocket science, really. Control add-ins are just pieces of HTML, CSS, and JavaScript running in an iframe, so whatever you can do within an iframe from anywhere else, you can do it from control add-ins. Web fonts are no different.

Control add-ins support packaging script, stylesheet, and image files. This could make you think that you cannot include web fonts. But that would be wrong.

As soon as you solve the problem of using HTML directly in your control add-ins, another problem arises: what do you do with actual images your control add-in includes?

This post explains how to solve that problem, and how to make it possible for your control add-in to both use HTML for defining UI and use relative control add-in paths to images.

Let’s dig in.
