Segmented/Pill Radio Input
A sliding segmented control that uses CSS Custom Properties calculated via JS to animate a pseudo-element background. The layout relies on flexbox for equal distribution, while calc() dynamically positions the “pill” based on the active index, enhanced by a springy cubic-bezier transition.
Round Cards
An aesthetic, minimalist gallery of circular elements where each card is uniquely composed (image on top, bottom, left, or right), creating visual variety within a strict grid.
Complex Navigation
A fully responsive, accessible mega-menu designed for e-commerce, featuring multi-column dropdowns and a mobile-friendly hamburger toggle.
Expanding Cards
A vertical neumorphic accordion that uses CSS Flexbox transitions to dynamically expand content panels. JavaScript toggles the .active class, triggering a smooth flex-grow animation that enlarges the selected panel while revealing its detailed content via opacity transitions, creating a tactile and responsive settings interface.
Sticky Header Calendar
A user-friendly calendar interface that functions seamlessly on both desktop and mobile devices, keeping context (time and day) constantly visible to the user, featuring both horizontal and vertical scrolling.
Expanding Flexbox Panels
This expanding panel gallery’s core animation is powered by CSS Flexbox, where the flex property is transitioned to create a fluid expansion effect. The state is managed by a minimal vanilla JavaScript snippet that simply toggles an .active class on click. This .active class also triggers a multi-layered text animation, using a delayed transition on the <h1>’s opacity and filter: blur() properties for a polished, cinematic reveal.
3D Text Shadow
An example of a complex text-shadow where SCSS is used to create a multi-layered shadow with precise offsets for each layer - this gives the text a dimensional, “cartoonish” effect that is unachievable with standard tools.
Click-to-Zoom Calendar
Explore responsive calendar design featuring a detailed hover and click zoom effect, implemented through precise coordinate calculations to manipulate CSS transform based on the selected date’s index.
Responsive Flexbox Slider
A responsive accordion in Vue.js where the panel expansion effect is implemented via CSS animation of the flex property - the state is changed with a simple click, without complex logic in JS.
Ticket

AutoSort ToDo List (CSS Only)
A ToDo list with a unique feature: automatic sorting of completed tasks to the end of the list, implemented without JavaScript, using the Flexbox order property and the powerful CSS :has() selector.

Interactive Color Palette Catalog with GSAP
A striking color palette catalog with an interactive design, employing GSAP and flex for a smooth expansive transition on click: the selected row enlarges while others shrink, creating a cinematic focus effect.
Responsive Speech Bubbles using CSS Container Queries
A stylish, pure CSS solution for creating speech bubbles with custom tails using the :after pseudo-element and the advanced clip-path: polygon() property to give the content frame a unique, angled edge shape.
Center-Mode Productivity Slider (Pro v5)
The “Accordion” effect is achieved using CSS transitions on the flex-basis property, while navigation is enabled via buttons, dots, or swipe detection with a separate Media Query for full responsiveness.
Responsive Front Page Article Layout with CSS Grid
This demo showcases a powerful responsive technique: a sophisticated CSS Grid layout for large screens gracefully degrades to a simple Flexbox-driven block flow on mobile devices, completely altering the structure for better readability.
Apple-Style Glass Card UI
This advanced CSS demo masterfully combines backdrop-filter: blur() for stunning translucent “glass” effects with smooth animations of decorative elements, focusing on modern aesthetics and interactivity.
Sleek Product Item

Card with Progress Steps
A state-driven stepper component whose styling is entirely managed by modifier classes - .stepper-completed, .stepper-active, and .stepper-pending. This approach allows for easy state changes without complex logic.
Movie Card: Pulp Fiction
A well-structured and responsive movie card where the layout is built using a combination of Flexbox and CSS Grid. All visuals - colors, shadows, spacing - are controlled via CSS Custom Properties, and the composition smoothly changes from a vertical to a horizontal layout via a media query.
Dotted Lines Between dt and dd Lists
A clean, modern technique for definition lists using Flexbox within the <dt> element to render a decorative, repeating fill (leader dots) before the description. The design employs the ::after pseudo-element and an SVG data URI to create visually consistent and flexible dotted lines across varying term lengths.
Upload UI
An adaptive UI component of cards for different states (loading, success, error), built on a scalable SCSS architecture. Color schemes are managed by variables, a custom @mixin handles the adaptive Flexbox layout via media queries, and a radial-gradient creates the glow effect.
