CSS Border Radius and Text Shadow Generator

This CSS effects project combines two common UI details: border radius for component shape and text shadow for display emphasis. Adjust each value, observe how the effect changes, and copy separate surface and title rules that stay easy to maintain.

Inside the project

How it works

Border radius is applied to the surface while the text shadow is applied only to the headline, keeping the two effects independently controllable.
Range controls update x, y, blur, and color values without relying on a prebuilt editor or CSS library.
The generated output separates the component surface rule from the text rule so the effect can be reused selectively.

Try it yourself

Run and customize it

01Adjust corner radius until the surface matches the surrounding design system.
02Use small text-shadow values first, then increase only if the headline loses contrast against its background.
03Copy the two rules into a local stylesheet and test them beside actual body text and controls.

Learning goals

What to study in this source

Use border radius as a consistent design token rather than a random value on every component.
Understand the x-offset, y-offset, blur, and color order used by text-shadow.
Keep display effects scoped to headings so paragraph text remains easy to scan.

Next experiments

Useful ways to customize it

Use separate radius values for cards, buttons, inputs, and pills in a small token scale.
Try a subtle low-opacity text shadow over an image background rather than a heavy black outline.
Add a border or background surface if contrast is still weak after testing the text shadow.

Common questions

CSS Border Radius and Text Shadow Generator FAQs

How do I make perfectly round CSS corners?

Use a border-radius of 50% on an element with equal width and height, such as an avatar or circular button. For pills, use a large value such as 999px so the radius exceeds half the element height.

What is the order of values in CSS text-shadow?

Text shadow follows horizontal offset, vertical offset, blur radius, and color. The generator exposes each value so you can see how a small change affects legibility and visual weight.

Should body text use text-shadow?

Usually no. Shadows can reduce clarity when used on small or dense paragraph text. Reserve them for short display text that sits over a visually complex background, and keep the blur and opacity restrained.

Can different corners have different border-radius values?

Yes. CSS accepts one to four values, letting you set a different radius for each corner. Use asymmetry only when it supports a deliberate component shape rather than making a shared design system inconsistent.

Does border radius clip child content?

Border radius shapes the element's border and background, but child content may still visually extend beyond it. Add overflow hidden when a child image or background needs to be clipped to the same rounded shape.
