How do I create a full-page gradient background in CSS?

Apply the gradient to the html or body element and set min-height: 100vh: body { background: linear-gradient(135deg, #1a1a2e, #0f3460); min-height: 100vh; }

How do I ensure text is readable over a gradient background?

Choose colours with enough contrast against your text colour. Use the WCAG contrast checker, and add a text-shadow or background overlay if needed for accessibility.

Can I animate a gradient background?

CSS cannot animate gradient colour stops directly with transition. Use background-position animation on a larger gradient (background-size: 200%) or use custom properties (CSS variables) animated with @property.

Can a gradient background replace an image?

Yes. Gradient backgrounds are lightweight (pure CSS, no HTTP request) and scale perfectly at any resolution — making them an excellent alternative to decorative background images.

How do I make a gradient that works on dark and light mode?

Define two gradient versions and switch between them with @media (prefers-color-scheme: dark). FixTools Dark Mode Gradient intent page has specific examples.
