I usually don't stop at 3 breakpoints when building a website.
Most people think about: Mobile, Tablet, Laptop
I like adding one more: Desktop
Because what looks great at 1440px can feel completely different at 1920px...
- The layout gets too wide.
- Spacing starts feeling off.
- Content loses its balance.
So I like testing the system across: Mobile → Tablet → Laptop → Desktop
Not because every website needs exactly 4 breakpoints. But because responsive design isn't about making a few screen sizes work.
It's about making the whole system work.
Follow Rushabh for more website fundamentals, experiments, and things I learn while building for the web.
Wide screens expose spacing issues that laptop previews can hide.
Designed a clean, premium website concept for Arave — a modern digital watch brand. Focused on strong visuals, product storytelling, and a minimal, technical feel.
Would love to hear your thoughts — what do you think I could improve in this project?
"Built to be taken apart" reframes repairability as the premium feature, not a compromise - most watch sites hide the mechanism, this one leads with it.
Well crafted, the details make this feel premium.
