Content before spectacle
The headline, offer and next step should appear without waiting for video or a graphics engine. A decorative scene should not be the only explanation of the company.
Keep readable text and links in ordinary HTML. Graphics strengthen the message without replacing accessible content or navigation.
Choose a light tool
CSS often handles entrances and button feedback. A small Canvas can render particles or procedural scenes. Complex 3D makes sense when depth explains the product or enables a useful interaction.
Begin with the simplest version and add complexity only when necessary. Fewer dependencies reduce transfer size and simplify maintenance.
Stop invisible work
An off-screen animation gives visitors no benefit. Track scene and tab visibility, cap pixel density and particle counts, and adapt complexity to the screen.
Respect reduced-motion preferences. The page should remain meaningful when movement is disabled or a device struggles with the effect.
Test the whole journey
Check navigation, forms, transitions and resizing as well as the hero. Test on phones and slow connections, and measure the final published page.
The goal is an expressive brand experience in which people can read, move and contact you without delays. Speed is part of design.
