About CSS Top Sites
CSS Top Sites is a reference and tutorial site focused on a single topic: backgrounds in CSS. Every page is built around the question a working developer or designer is most likely to type into a search bar — how a property behaves, which value to choose, how a particular visual effect is constructed, and what the trade-offs are.
Who the site is for
The audience is people who write CSS for a living or for a hobby project: front-end developers, full-stack engineers who occasionally touch styling, designers comfortable working in code, students building their first portfolio, and anyone trying to make a hero section, dashboard, or landing page look right on more than one screen size. The reference pages assume basic familiarity with HTML and CSS syntax; the tutorial pages assume nothing beyond that.
What the site covers
The catalog is intentionally narrow. It covers:
- Each individual CSS background property —
background-color,background-image,background-size,background-position,background-repeat,background-attachment,background-origin,background-clip,background-blend-mode, and thebackgroundshorthand. - Composite techniques such as multiple backgrounds, gradient meshes, blend-mode layering, glassmorphism on dark backgrounds, parallax, animated backgrounds, SVG patterns, and video backgrounds.
- Color combinations applied to dark and black backgrounds, including red, blue, green, purple, gold, and smoke effects.
- A free, browser-based CSS background generator that produces copy-pasteable CSS for solid colors, linear and radial gradients, and patterns.
Editorial approach
Each tutorial page has the same structure: a short explanation of what a property or technique does, one or more live demos rendered with pure CSS, copy-ready code, and notes on edge cases that commonly trip people up. Reference pages list every value, what it means, and a working example.
The site does not chase trends, frameworks, or "best of [year]" roundups. CSS background behaviour changes slowly, and the goal is for a guide written today to still be correct in two years.
How content is produced
Pages are written in plain HTML and CSS. Every code sample is intended to be runnable as-is in a current evergreen browser; where a feature has uneven support (for example, backdrop-filter, color-mix, or image-set()), the page calls that out so a reader knows whether to ship it or hold off. References are cross-checked against the W3C CSS Backgrounds and Borders specification and MDN's CSS reference.
Examples and demos are built from generic patterns — the colors, gradients, and shapes you see are illustrative, not screenshots of any specific real-world site. Where a page recommends a value or approach, the recommendation reflects general industry practice, not personal advocacy.
What's not on the site
To keep the scope honest: there is no coverage of unrelated front-end topics such as JavaScript frameworks, build tooling, or accessibility outside of how it intersects with backgrounds. There is no paid review, no sponsored content embedded inside articles, and no testimonials. Links pointing off-site go to vendor-neutral resources such as MDN, the W3C, and Can I Use.
