Frequently Asked Questions
What is CSSForge?
CSSForge is a free online CSS toolbox with 35+ professional tools for developers. It includes generators for gradients, shadows, animations, glassmorphism, neumorphism, media queries, and much more — all with live preview and one-click copy.
Are all tools free to use?
Yes. All tools on CSSForge are completely free. No account required, no limits.
What is the CSS specificity calculator?
The CSS specificity calculator lets you enter any CSS selector and instantly see its (a, b, c, d) specificity score with a full breakdown by IDs, classes, and elements. You can compare multiple selectors side by side.
What is glassmorphism in CSS?
Glassmorphism is a design trend that uses backdrop-filter: blur() combined with a semi-transparent background to create a frosted glass effect. CSSForge's glassmorphism generator lets you control blur, opacity, saturation, and border with live preview.
What is neumorphism?
Neumorphism (soft UI) is a design style using subtle shadows to make elements appear extruded from the background. It uses two shadows — one dark, one light — to create depth. CSSForge supports flat, pressed, convex, and concave variants.
How do CSS container queries differ from media queries?
Media queries respond to the viewport size, while container queries (@container) respond to the size of a parent element. This makes components truly self-contained and reusable. CSSForge's Container Query Builder helps you write modern container queries with live preview.
