Build with context

What these projects teach

This collection covers two practical approaches to browser animation: continuously rendered JavaScript Canvas scenes and declarative CSS keyframe sequences. The projects include the complete page structure and styling, so you can study how the visual layers, timing, responsive sizing, and rendering choices work together.

Use the live preview to observe movement at normal speed, then inspect the original source beside it. Canvas projects are useful for particles, procedural texture, and effects that change every frame. HTML and CSS projects are useful when element-based layers and repeatable keyframes can describe the scene without a JavaScript loop.

Learning outcomes

Skills you can practice

  • Compare Canvas frame rendering with CSS keyframe animation and choose the simpler approach for a specific visual effect.
  • Understand how gradients, compositing, particles, layered elements, transforms, and timing combine into a finished browser scene.
  • Keep an animation sharp and correctly framed when the viewport changes on phones, tablets, and desktop displays.
  • Identify performance-sensitive values such as particle count, device pixel ratio, shadow blur, and simultaneous animated elements.

Practical workflow

From preview to your own version

  1. 01Watch the original animation in normal and fullscreen preview to identify its major visual layers.
  2. 02Read the HTML structure first, then follow the CSS keyframes or Canvas drawing passes responsible for each layer.
  3. 03Adjust colors, timing, density, or motion in a local Code Studio copy while preserving the original project.
  4. 04Check the edited result at small and large viewport sizes, then download the complete source when it is stable.

Common questions

Web Animations FAQs

What is the difference between CSS and JavaScript Canvas animation?

CSS animation changes element styles through keyframes and works well for repeatable interface or character motion. Canvas animation redraws pixels with JavaScript every frame, making it better suited to particles, procedural texture, simulations, and continuously changing effects.

Can I run these web animations without a build command?

Yes. The current projects are portable browser pages that run from their supplied HTML entry file. Download the ZIP, extract it, and open the entry file in a modern browser without installing a framework or external package.

How should I test a customized browser animation?

Compare the edited version with the original, watch several complete loops, and test both normal and fullscreen preview. Check a narrow phone width and a wide desktop width, paying attention to framing, timing, text overlap, and rendering smoothness.
