Overview
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.

1. 3-Column Preview Card Component
Multi-column layout component for a vehicle category showcase.
A three-panel card component presenting Sedans, SUVs, and Luxury vehicles in a horizontally arranged layout. Each column features a category icon, descriptive body copy, and a styled “Learn More” CTA button — with distinct color themes per column.

2. NFT Preview Card Component
Digital collectible card with overlay interaction and creator attribution.
A polished NFT preview card displaying a digital artwork image, token name, description, ETH price, time remaining, and creator profile. Features an image overlay effect on hover — revealing a view icon over the NFT artwork.
Design challenge: Implementing the image hover overlay using CSS position, opacity, and transition — without JavaScript — while maintaining exact color values and spacing from the design file.
| Detail | Implementation |
|---|---|
| Hover overlay | CSS position: absolute with opacity transition |
| ETH + clock icons | Inline SVG icons with precise sizing |

Design challenge: Implementing a responsive image swap — different images served at mobile vs desktop breakpoints using <picture> and srcset — without any JavaScript or layout shift.
| 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 |

5. Profile Card Component
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 |
| Stats row | Three-column Flex layout with vertical label+value pairs |

6. Results Summary Component
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.
| Detail | Implementation |
|---|---|
| Circular score | CSS border-radius: 50% with background: linear-gradient() |
| Category rows | Four flex rows, each with unique background-color at low opacity |
| Color coding | Reaction (red), Memory (yellow), Verbal (teal), Visual (blue) |

| Responsive | Stacks vertically on mobile; two columns on desktop |
Key Skills: Circular gradient UI element · CSS Grid two-panel layout · Color-coded category rows · rgba tinted backgrounds · Assessment dashboard UI pattern
7. Stats Preview Card Component
Business analytics card with image overlay tint and three-column statistics.
A data analytics marketing card featuring a headline, body copy, a three-column statistics row, and a product image with a colored overlay tint — the kind of component seen on SaaS and analytics platform landing pages.
Design challenge: Applying a specific violet color overlay tint to the image without altering the underlying image file — achieved using CSS mix-blend-mode or an absolutely positioned pseudo-element with opacity.
| Detail | Implementation |
|---|---|
| Image tint overlay | ::after pseudo-element with mix-blend-mode: multiply |
| Two-column layout | CSS Grid — content left, image right at desktop |
| Stats row | Three inline stat blocks with label and large numeric value |
