This repository contains 7 UI component projects completed on Frontend Mentor — a platform trusted by over 500,000 developers worldwide for practicing frontend skills against professionally designed, real-world briefs.
Each challenge provides a Figma or image design specification and requires the developer to implement a pixel-accurate, responsive HTML and CSS solution entirely from scratch — no starter CSS, no component libraries, no UI frameworks.
These projects demonstrate the ability to translate a visual design into clean, semantic, maintainable frontend code — a core skill evaluated in frontend engineering interviews and client projects globally.

| Detail | Implementation |
|---|---|
| Responsive image | <picture> with <source media="(min-width: 600px)"> for desktop art |
| Pricing display | Discounted price prominent; original price in muted strikethrough |
| Add-to-cart button | Flex row with SVG cart icon, hover color transition |

Social media profile card with background pattern and social statistics.
A personal profile card displaying a user avatar, name, age, location, and a three-column social statistics row (followers, likes, photos). Features a two-tone background with intersecting curved SVG shapes — a precise CSS positioning challenge.
Design challenge: Positioning two decorative background circle SVGs — one in the top-left, one in the bottom-right — so they appear to extend beyond the card boundaries without causing scroll or overflow at any viewport size.
| Detail | Implementation |
|---|---|
| Background pattern | Two SVG circles positioned with position: absolute at card corners |
| Avatar border | Circular border-radius: 50% with border: 3px solid white |

Assessment results card with category breakdown and score visualization.
A two-panel results card of the type used in ed-tech and assessment platforms. The left panel shows an overall score inside a circular gradient display; the right panel lists four performance categories (Reaction, Memory, Verbal, Visual) each with an icon, category score, and color-coded background.
Design challenge: Creating the circular score display using CSS — achieving the gradient ring effect and centered score percentage — and matching the four individually color-themed category rows without repeating CSS unnecessarily.
