How to generate CSS for a button

A button's resting style is a small set of properties: a background, a text colour, some padding, a corner radius, a weight, and a pointer cursor. Getting those right takes a minute, and the preview here shows you exactly how the combination will render.

What the generated rule deliberately does not include is the interactive states, and those are where a button becomes usable. Plan to add hover, active, and focus-visible rules on top of what you copy.

  • Choose the background and text colours, and check the pair reaches a contrast ratio of at least 4.5:1.
  • Set the padding, keeping the horizontal value at roughly twice the vertical so the button is not cramped.
  • Set the corner radius, from square through to a fully rounded pill.
  • Copy the rule and apply it to a real button element rather than a styled div.
  • Add :hover, :active, and :focus-visible rules of your own, with a short transition, because the generated rule covers the resting state only.
Tips

Getting a better result out of CSS Button Generator

Specific settings and thresholds, not general advice.

  • The generated rule has no focus style, and that is the one you cannot skip. A keyboard user needs to see where they are, so add a :focus-visible rule with a visible outline and an outline-offset. Removing or forgetting the focus ring is one of the most common accessibility failures on the web.
  • Check the contrast between your text colour and your background colour. WCAG asks for at least 4.5:1 for normal text and 3:1 for large text, and a mid-tone brand colour with white text very often lands around 3:1, which fails. The colour picker will not stop you.
  • The rule covers the resting state only. A button that does not visibly change on hover and on active feels broken, so add a :hover with a slightly darker background and an :active that shifts it a pixel or reduces the brightness, with a short transition to smooth it.
  • Horizontal padding should be roughly double the vertical, which is what the generated rule does. That ratio is what makes a button look like a button rather than a squashed box, and it is worth preserving if you adjust the values.
  • Use a real button element, not a styled div. A button is focusable, is announced correctly by screen readers, fires on the Enter and Space keys, and participates in form submission, and reimplementing all of that on a div is a lot of work to arrive back where you started.
Limits

What CSS Button Generator does not do

The honest boundary, so you do not lose time finding it yourself.

  • It generates the resting state only, with no :hover, :active, :focus-visible, or :disabled rules.
  • It adds no transition, so any state change you write yourself will snap rather than ease.
  • It does not check colour contrast, so it will happily produce a button whose label fails WCAG against its background.
  • It generates a flat, solid button, with no support for outline, ghost, or gradient variants.

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Is the CSS button generator free?

Yes. It is completely free to use, with no signup, no account, and no paywall.

Can I use the generated CSS in commercial projects?

Yes. The CSS you copy from the tool is yours to use in any project, personal or commercial, with no attribution needed.

Does it stay local?

Yes. Everything runs in your browser, and nothing you configure is uploaded to a server.

What is missing from the generated rule?

The states. What you get is how the button looks when nothing is happening to it, and a real button needs at least three more rules: :hover, so a mouse user gets feedback; :active, so a click feels like a press; and :focus-visible, so a keyboard user can see where they are. The focus style is the one with genuine consequences, because without it the interface is unusable without a mouse. Add a transition on the background and the transform to make the changes feel smooth.

Is my button accessible?

Not automatically, and two things need checking. First, contrast: the label must reach a ratio of 4.5:1 against the button background for normal text, and a mid-saturation brand colour with white text frequently comes in below that. Second, focus: the rule sets border: none, and if you also remove the outline you have made the button invisible to keyboard users. Use a real button element, keep a focus-visible outline, and run the two colours through a contrast checker.

Why is the horizontal padding twice the vertical?

Because that is the ratio that reads as a button. A control with equal padding on all sides looks cramped and square, and the eye expects a label to have more breathing room to its left and right than above and below. Most design systems land somewhere between 1.5 and 2.5 times as much horizontal padding as vertical. If you change the vertical padding, scale the horizontal one with it rather than fixing it.

Should I style a div as a button?

No. The button element is focusable without a tabindex, is announced as a button by screen readers, activates on both Enter and Space, can submit a form, and is disabled correctly by the disabled attribute. Recreating that on a div means adding a role, a tabindex, key handlers for two keys, and a disabled state that also removes it from the tab order, and getting one of them wrong is the norm. Use the element that already works.

Is the preview rendered locally?

Yes. It is a real button element with the generated CSS applied, rendering in your browser, and nothing you configure is transmitted.
