SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

GSAP core enables precise, high-performance web animations by giving a compact API for tweens, timelines, and CSS transforms, avoiding layout thrashing and ensuring smooth transitions.

Core Features & Use Cases

  • Core Tween Methods: gsap.to(), gsap.from(), gsap.fromTo(), gsap.set() and camelCase property usage for predictable styling.
  • Transforms & CSS Properties: use transform aliases for performant, consistent animations on DOM/SVG elements, including autoAlpha for accessible fades.
  • Responsive & Sequencing: utilize gsap.matchMedia() for responsive and prefers-reduced-motion scenarios; coordinate multiple animations with timelines.
  • Practical Use Case: create a simple intro animation for a card, then sequence a follow-up parallax effect on scroll with ScrollTrigger (related concept).
  • Performance Best Practices: prefer transforms over layout properties.

Quick Start

Create a basic GSAP tween on a DOM element to move it 100px to the right over one second.

Frequently Asked Questions about gsap-core

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create high-performance web animations without causing layout thrashing?▼

GSAP core enables high-performance web animations by using transform aliases and a compact tween API, preventing layout thrashing and ensuring smooth CSS transitions on DOM elements.

Can I use GSAP animations in React, Vue, and Svelte projects?▼

Yes, GSAP core is applicable to React, Vue, Svelte, or vanilla JavaScript projects. It efficiently animates web UI elements using core tween methods across these frameworks.

How do I handle prefers-reduced-motion scenarios when building JavaScript animations?▼

You handle prefers-reduced-motion scenarios by utilizing gsap.matchMedia() for responsive animations, ensuring your web UI elements adapt appropriately to user accessibility preferences.

What is the best way to sequence multiple tweens into a coordinated timeline?▼

The best way to sequence multiple animations is using GSAP timelines, which coordinate multiple tweens to create complex, predictable UI transitions without layout thrashing.

Why should I use transform aliases like autoAlpha instead of layout properties in GSAP?▼

You should use transform aliases like autoAlpha because GSAP core enforces performance best practices by preferring transforms over layout properties, enabling accessible fades and consistent DOM animations.

Do I need ScrollTrigger to build scroll-based parallax effects with GSAP core?▼

GSAP core handles the foundational tweening for scroll-based parallax effects, but a related concept like ScrollTrigger is needed to tie those animations directly to scroll positions.
