How to Use the CSS Generator

The CSS Generator is a free online visual tool that helps web developers and designers create CSS properties without writing code manually. It features three powerful modules: Box Shadow, Border Radius, and Gradient generators, each with intuitive slider controls and real-time preview. All CSS code is generated instantly as you adjust the controls, and you can copy the output with a single click. This tool runs entirely in your browser with no external dependencies or server communication required.

Box Shadow Generator

The CSS box-shadow property adds shadow effects around an element. It accepts values for horizontal offset, vertical offset, blur radius, spread radius, and color. The inset keyword creates an inner shadow instead of the default outer shadow. Box shadows are one of the most commonly used CSS properties for adding depth and visual hierarchy to web interfaces. They can simulate elevation in Material Design, create neumorphic effects, add focus indicators for accessibility, and provide subtle depth cues that guide user attention. Multiple box shadows can be layered for more complex effects, and they can be animated with CSS transitions for interactive hover states and focus effects.

Border Radius Generator

The CSS border-radius property rounds the corners of elements. It can accept a single value that applies to all four corners equally, or four individual values for the top-left, top-right, bottom-right, and bottom-left corners respectively. Border radius is fundamental to modern web design, used for creating rounded buttons, pill-shaped tags, circular avatars (with 50% radius), card components, and soft UI elements. The linked mode in this tool lets you adjust all corners simultaneously for uniform rounding, while the unlinked mode gives you independent control over each corner for asymmetric designs.

CSS Gradient Generator

CSS gradients create smooth transitions between two or more colors. Linear gradients flow in a straight line at a specified angle, while radial gradients emanate from a central point outward. Gradients are widely used for backgrounds, overlays, buttons, progress bars, and decorative elements. They eliminate the need for gradient images, reducing page load times and enabling resolution-independent designs that look sharp on all screen densities. The angle control for linear gradients lets you create horizontal (90deg), vertical (180deg), diagonal (45deg), and any custom direction. CSS gradients are supported in all modern browsers and are a cornerstone of contemporary web design.
