Accordion FAQ Menu
A smooth, responsive FAQ list where content unfolds with a natural sliding animation, and indicators (arrows) clearly show the state of each item.
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.
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.
Nested Accordion FAQs
A multi-level FAQ accordion implemented in vanilla JS. The classic technique of setting panel.style.maxHeight = panel.scrollHeight + "px" is used to expand panels, ensuring a smooth height transition
FAQ Accordion
An effective pattern for an FAQ component in pure JS and CSS - a forEach loop ensures all inactive tabs are closed, while CSS, via the single .show-text class, atomically controls the answer’s visibility and the icon switch.
Simple Image Accordion
An implementation of a responsive accordion using Flexbox, where the smooth expansion of sections is achieved by animating the CSS flex property. A vanilla JS script is used only to toggle the .accordion__item_active class on click.
FAQ Accordion with Font Awesome Icons
The “Accordion/FAQ” functionality is implemented using pure JavaScript, which handles the click on the parent element and toggles the active class on the FAQ container. The visual highlight is the icon change via CSS display: none/block properties.
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.
Accordion Slider with Vanilla JS
This is a fully responsive accordion slider built with vanilla JavaScript and CSS, handling both click and keyboard arrow events for seamless slide navigation.
