Generate CSS border styles visually with live preview
Visually design CSS borders with full control over width (per side), style, color, and border-radius (per corner). See changes in real-time and copy the generated CSS code in shorthand or longhand format. Perfect for rapid prototyping and learning CSS border properties.
CSS borders define the edges of elements and are fundamental to web layout. Beyond simple solid lines, CSS supports ten border styles: solid, dashed, dotted, double, groove, ridge, inset, outset, hidden, and none. Each side can be independently styled for creative effects. Combined with border-radius for rounded corners, borders create everything from simple card outlines to decorative dividers and shaped elements. This generator provides real-time preview as you configure each property, supporting shorthand (border: 2px solid #333) and individual side declarations. It handles the full border specification including style, width, color, and radius — generating clean, copy-ready CSS for your project.
border: width style color — e.g., 'border: 2px solid #333'. Order matters: width first, then style, then color. You can omit values and they'll use defaults (medium, none, currentColor).
Use border-top, border-right, border-bottom, border-left with the same shorthand. Or use specific properties like border-left-color, border-top-width for precise control.
Both create 3D effects using the border color. Groove appears carved into the page (shadow on top-left, highlight on bottom-right). Ridge is the opposite — appears raised. The effect depends on the border color.
Set border: none to remove all borders, then add the side you want: border-bottom: 2px solid #333. This is common for underline effects on navigation links and section dividers.
By default, borders add to the element's total size. Use box-sizing: border-box to include borders in the specified width/height. Most CSS resets set this globally to avoid unexpected sizing.
