Frequently Asked Questions

What is the best CSS for a pure black background?

The most straightforward way is using background-color: #000; or background-color: black;. For better browser support and consistency, hexadecimal values are recommended.

How do I create a black gradient background?

Use CSS gradients: background: linear-gradient(to bottom, #000, #333); for linear gradients or background: radial-gradient(circle, #111, #000); for radial gradients.

Can I combine black backgrounds with images?

Yes! Use multiple backgrounds: background: linear-gradient(rgba(0,0,0,0.8), rgba(0,0,0,0.8)), url('image.jpg'); to create overlays.
