CSS tools

CSS tools turn visual decisions into the CSS code that produces them. The two most- used are box shadows (multiple offsets, blurs, and colors stacked into a layered shadow) and gradients (linear, radial, conic with multiple color stops). Both are easier to reason about visually than by typing CSS values blind — these tools give you a visual builder with the matching CSS code updating live.

The box shadow generator handles up to four stacked shadows with offset (X, Y), blur radius, spread, color, and inset toggle for each. The CSS output updates as you drag the controls. Useful for material-design-style elevation effects (multiple soft shadows at different blurs) and for inset shadows used in form fields and pressed buttons.

The CSS gradient generator builds linear, radial, and conic gradients with multiple color stops at configurable positions. Pick the gradient type, drag stops along the axis, set the angle (for linear) or center/shape (for radial). Output is the CSS gradient function ready to paste into a background or background-image declaration. Both tools generate standard CSS that works in every modern browser without prefixes — vendor prefixes are no longer required for these properties as of about 2018, so the output is the simple, modern form.
