A few of my favorite design resources...
This was my go-to guide when I was first learning about typography.
Visual design theory can be difficult to apply, which is why I love Steve's articles: the tips are actionable and go a long way in providing visual polish.
A well-crafted and flexible icon set (that you don't have to make from scratch) is invaluable. I love that FontAwesome provides such a wide range strokes and weights.
Pexels provides a bunch of high-quality photos for free. One caveat: some photos are now widely used and can seem "stock" and less authentic.
Mobbin collects screens from various mobile apps. Not only is the content helpful to reference (you can filter by app or specific patterns), I love how clean the site is.
Grow.design provides a series of thoughtful app critiques and analyses in a fun (bitmoji) format.
It can be difficult to sift through all the activity in the design community. Sidebar.io sends me (just) 5 curated links every day so I can catch up on what's worthwhile.
I love receiving my weekly dose of typographic inspiration from Jeremiah Shoaf at Typewolf. He identifies new trends in typography and highlights websites that use typography beautifully.
Elizabeth Lin writes great articles about teaching and learning design, backed by her experiences working at Khan Academy and Lambda School. I love how accessible her articles are – great for early and senior designers.
