Free CSS Generators — Box Shadow, Border Radius & Clamp

Three new CSS generators are now live on ToolStand, designed to help you style faster and with more precision. Tweak box-shadow, border-radius, and clamp() values through visual controls with instant live previews — then copy clean, production-ready CSS with one click. No more guessing hex values or fiddling with DevTools just to get your shadows and curves right.

🎨 CSS Box Shadow Generator

Dial in the perfect shadow with independent controls for horizontal offset, vertical offset, blur radius, spread radius, and color. A live preview box updates in real time as you adjust each slider — you can see exactly how the shadow will render before you commit to code. Toggle between box-shadow and inset modes, and copy the completed CSS declaration with one click. Perfect for card components, buttons, modals, and any element that needs depth.

⭕ CSS Border Radius Generator

Control every corner independently — top-left, top-right, bottom-right, bottom-left — in pixels or percentages. A live preview shape shows the rounded rectangle as you adjust each value. The lock corners toggle keeps all four corners equal when you want uniform rounding (like a pill button or circle), or unlock it to create asymmetrical shapes like chat bubbles and tabs. Copy the full border-radius shorthand or the expanded four-value syntax with a single click.

📐 CSS Clamp Generator

Fluid typography and spacing made simple. Set minimum, preferred (viewport-based), and maximum values using px, rem, or vw units. A live preview renders text at different simulated viewport widths so you can see how your clamp expression behaves across mobile, tablet, and desktop breakpoints. Built-in preset examples — like fluid headings, responsive margins, and adaptive font sizes — help you get started instantly. Copy the final clamp() expression with one click and drop it directly into your stylesheet.

Why use CSS generators?

Hand-tweaking CSS values in DevTools works, but it's slow. You type a number, hit Enter, squint at the preview, tweak again, repeat. CSS generators flip that workflow: you drag a slider, see the result instantly, and once it looks right you copy the code. That means fewer iterations, zero syntax errors, and output that's ready for production. For values like box-shadow with five parameters or clamp() with mixed units, a visual editor removes the mental math and lets you focus on the design.
