Pattern Background Generator

Pure CSS, no image files

Every pattern here is drawn with CSS gradients on top of a solid background-color. There is nothing to host and no extra HTTP request: the whole texture lives in the stylesheet. A dots pattern, for example, looks like this:

.hero {
  background-color: #1F2937;
  background-image: radial-gradient(#FFFFFF 1px, transparent 1px);
  background-size: 20px 20px;
  background-repeat: repeat;
}

CSS backgrounds repeat by default. The generated size and position values are chosen to align each motif as it repeats, though rendering can vary slightly with browser zoom and fractional device pixels. Change the spacing value to make the texture denser or more open.

What each motif is made of

Color and contrast tips

• Keep the contrast low for backgrounds. A pattern color close to the background color usually reads as a subtle texture. High contrast can compete with the page content.
• Match your brand. Use a brand color as the pattern color instead of plain gray so the texture fits the surrounding design.
• Dark mode. Try a dark background color and a slightly lighter pattern color. Strong contrast can look noisy on a large dark surface.
• Check text against both colors. If text sits over the pattern, test its contrast against the background color and the pattern color wherever either can appear beneath a glyph. This generator previews the pattern but does not perform a WCAG contrast audit.

Where to use it

• Hero and section backgrounds that need a little texture without an image.
• Cards and panels in a dashboard, where a faint grid or dots adds structure.
• Empty states and placeholders, where a checkerboard reads as neutral.
• Print-style layouts and slides that call for a graph-paper or crosshatch feel.

Because the pattern is CSS rather than a separate background asset, it does not add an image request. You can also adjust its gradient, size and position values later in browser developer tools.
