FAQ
- What is mobile-first?
- Design uses min-width blocks to expand layouts on wider viewports.
- If I set the tablet and desktop breakpoint to the same number, like 768px, won't the two ranges overlap?
- A browser only applies the rule that matches a given width, so nothing technically breaks, but pairing max-width and min-width at the exact same value can cause unexpected style clashes. It's safer to offset one side by 1px, for example max-width: 767px paired with min-width: 768px, so the ranges split at a clean boundary.
