Building a Responsive Feature Section: My CSS Challenge from DevChallenge

#webdev #css #frontendchallenge #100daysofcode

Introduction

I recently completed the “Simple Feature Section” challenge from DevChallenges.io 🎉.

The goal was to take a design mockup and turn it into a fully responsive HTML & CSS layout, ensuring it works seamlessly across desktop, tablet, and mobile.

Skills & Concepts Applied

--> Responsive Design: Mobile-first approach using CSS flexbox and media queries
--> CSS Styling: Modern, clean, maintainable CSS for a polished UI
--> Pixel-perfect Layout: Matching the design mockup closely
-> Deployment: Hosted live on Vercel to showcase a working demo

Project Demo

Here are some screenshots of the responsive layout:

What I Learned

--> How to structure HTML for clean, semantic markup
--> Managing responsive breakpoints efficiently
--> Improving workflow from design to deployment
--> Debugging CSS issues across multiple screen sizes

Conclusion

Completing challenges like this is a great way to strengthen frontend skills, improve responsiveness, and build a portfolio that recruits attention.

I’m looking forward to sharing more projects and tutorials as I continue my journey as a Full Stack Developer.
