How do I make a boundary perfectly sharp?

Give the two colors meeting at the boundary the same stop position — the transition width becomes zero. The preview shows a hairline if the positions are even slightly apart.

Do hard-stop stripes scale without blurring?

Yes — they are vector geometry computed by the browser at display resolution, so edges stay crisp at any size, unlike sliced background images.

Can the stripes repeat?

The tool builds one explicit sequence; CSS repeating-linear-gradient extends the same construction for wallpaper-style repetition — the gradient previewer verifies those values.

Why does my stripe show a faint blend line?

The paired stops are not exactly equal — a fraction of a percent apart leaves a hairline of transition. Nudge the positions to match and the line disappears.

How many stops does one crisp band need?

Two per boundary, so a two-colour split comes to four entries — the first band's colour at 0% and again at 50%, the second band's colour at 50% and again at 100%. Every stop is written out explicitly in the declaration, so the stop count grows twice as fast as the number of stripes.

The hard-stop gradient generator builds gradients whose stops touch — sharp boundaries instead of blends — for stripes, segments and stepped fills in pure CSS.

What is Hard-Stop Gradient Generator?

Most gradients exist to blend; the hard-stop gradient exists to refuse. When two stops share a position, the gradient produces no transition at all — an instant switch from one color to the next — and that refusal is the raw material of CSS stripes, segmented progress bars, stepped backgrounds and the crisp color-block effects that blends cannot make. The hard-stop gradient generator builds those: set the colors, set the boundary positions, and the preview shows the sharp-edged result with the CSS ready to copy.

The technique inverts normal gradient intuition: an ordinary two-stop gradient blends across the whole span, while placing both stops at 50% compresses the transition to zero width and turns a gradient into a boundary.
Add more touching pairs and the result is a stripe pattern — as many bands as the stops define, every edge crisp at any resolution because it is vector geometry rather than drawn pixels.
That is what makes a stripe gradient css approach better than sliced background images: it scales, it needs no assets, and the bands stay editable as colours and percentages.

Every stop's colour and position are set independently, so a three-stripe flag, a segmented meter or a stepped heat scale is a matter of pairing stops correctly — two per boundary, adjacent stops sharing a position.
The preview does the checking: touching stops that are off by a fraction render as a visible hairline of blend rather than a crisp edge.
Reading the finished declaration back is how the pattern gets recorded, because the stop positions are the part that has to be reproduced at another size.

Hard stops are the cheapest way to get several flat colours out of a single background, and they are used far less often than they deserve. Because a hard stop creates an edge rather than a blend, the technique replaces extra elements: a three-tone backdrop becomes one declaration, a striped pattern becomes one property, a progress track becomes a set of proportional bands. It is also the most predictable member of the gradient family, since nothing between the stops is interpolated and therefore nothing can band, and every value is exactly the value written. Keeping the stops on a scale — at ten, forty and one hundred per cent, say — turns the technique into something a reader can decode, because the proportions then mean something rather than reflecting a drag that happened once. Used that way, a hard stop gradient generator produces structure: dividers, gauges and backgrounds in which the boundaries are the design.

As a sharp gradient boundaries instrument, it is the specialist in the gradient family — the no blend gradient tool for when the brief says crisp. For genuine blends, the linear and multi-stop builders are the right instruments; for repeating stripe patterns specifically, CSS repeating gradients extend the same trick, and the previewer can verify those values too.

Record the stop percentages with the palette, because a pattern assembled from guessed positions is hard to reproduce at another size, while one built on a scale adapts simply by rescaling the numbers.

How to use Hard-Stop Gradient Generator

Set each band's color as a stop.
Pair stops at shared positions so each boundary has zero width — the preview shows crisp edges.
Copy the CSS; the stripes are vector-sharp at any size.

When to use Hard-Stop Gradient Generator vs related tools

Use this for stripes, segments and stepped fills that must not blend. Use the multi-stop builder for genuine blends with interior positions, the linear generator for simple two-color washes, and the previewer to fine-tune hand-written values. When the structure comes first and the blending second, the gradient color stop editor works the same boundaries on a fixed horizontal axis, and if the bands should actually melt into each other, the multi-stop gradient builder is the general form.
