As answered by people managing Duo Security and CSSBackgrounds.
CSSBackgrounds's answer:
Everything is pure CSS. Most background sites hand you an image file; here every pattern and gradient is a few lines of code with nothing to download. You get live controls for colors and size, the choice of CSS, Tailwind, HTML or PNG output, and colors set as CSS variables, so you can retheme a background later (dark mode included) by changing one line.
CSSBackgrounds's answer:
I've run SVGBackgrounds.com since 2018, and the most common thing people want is a nice background they can drop into a site fast. A lot of that can be done with CSS alone now, so I built a free sister site for it: no images, no account needed, just copy and paste the code.
CSSBackgrounds's answer:
It's free and brand new, so no big names yet. It's built for indie developers, designers and small agencies.
CSSBackgrounds's answer:
Web developers and front-end designers building landing pages, hero sections, cards, portfolios and app UIs who want a subtle texture or a bold gradient without hunting for stock images or adding page weight.
