CSS Helper Tool FAQ
What CSS effects can I generate with this tool?
Nine kinds: box shadows (several layers, inset or outside), background gradients (linear, radial and conic with up to 8 colors), box model and borders (size, padding, border and per-corner radius), CSS transforms (rotate, scale, skew, move and 3D), keyframe animations (12 presets including bounce, shake, pulse and flip), CSS filters (blur, brightness, contrast, grayscale, sepia, hue-rotate and more), glassmorphism, neumorphism (soft UI) and text shadows.
How do I copy the generated CSS code?
Adjust the sliders, colors and presets and the preview updates as you go. Press Copy CSS under the controls to copy the finished rule to your clipboard, open the CSS tab to read it first, or download it as a .css file.
Is the CSS Helper Tool free to use?
Yes, the CSS Helper Tool is completely free to use with no registration required. You can generate unlimited CSS code for shadows, gradients, animations, transforms, glassmorphism, neumorphism, filters and text shadows. Everything runs in your browser and nothing is uploaded.
How do I add multiple box shadows in CSS?
List them in one box-shadow declaration, separated by commas; the first shadow sits on top. In the Box shadow generator, Add layer stacks another shadow, and each layer has its own offset, blur, spread, color, opacity and inset setting.
How do I make a glassmorphism effect in CSS?
Give the element a semi-transparent background, a backdrop-filter blur and a thin light border, then place it over something colorful. The Glass generator writes all of it, including the -webkit-backdrop-filter line that older Safari versions need.
Do CSS gradients work in all browsers?
Yes. Linear, radial and conic gradients work without prefixes in every current version of Chrome, Edge, Firefox and Safari. The tool writes the standard syntax, so the CSS you copy works as it is.
