Question 4

What is a mobile-first approach to breakpoints?

Accepted Answer

Mobile-first design means writing base styles for small screens first, then using min-width media queries to apply larger-screen styles. Tailwind and Bootstrap both follow this approach.

Question 5

Can I define custom breakpoints?

Accepted Answer

Yes. In Tailwind, you can extend breakpoints in tailwind.config.js. In Bootstrap, SCSS variables can be overridden. This visualizer also lets you create custom breakpoints to compare them side by side.
