Frank Chimero, writing for Typekit:
On the web, a large chunk of our content is text. This means it’s important to understand how to reinforce this hierarchy typographically. A clear understanding of hierarchy results in more beautiful, meaningful, and communicative designs that better serve their audience.
I’m going to address these concepts with an example that slowly builds complexity by introducing new visual elements. With each step I’ll add a new tool to support the hierarchy.
After a six-step conceptual exercise, Frank goes on to evaluate examples in the wild.
