reset-button.css

%reset-Button {
    border: none;
    margin: 0;
    padding: 0;
    width: auto;
    overflow: visible;

    background: transparent;

    /* inherit font & color from ancestor */
    color: inherit;
    font: inherit;

    /* Normalize `line-height`. Cannot be changed from `normal` in Firefox 4+. */
    line-height: normal;

    /* Corrects font smoothing for webkit */
    -webkit-font-smoothing: inherit;
    -moz-osx-font-smoothing: inherit;

    /* Corrects inability to style clickable `input` types in iOS */
    -webkit-appearance: none;
}

/* Remove excess padding and border in Firefox 4+ */
&::-moz-focus-inner {
    border: 0;
    padding: 0;
}

I think this is missing.

text-align: inherit;

Nice gist!

I think this is missing:

outline: none;

@ArtemFitiskin
That's not good for accessibility :)

Consider adding border-radius: 0; for iOS – in case someone uses

<input type="button" value="Button" />
<input type="submit" value="Submit" />
<input type="reset" value="Reset" />

:-)

Don't forget that text in a button is vertically centered.

If you stumbled upon this ancient(in web timeline) gist and want to remove outlines consider using:

  :focus:not(:focus-visible) {
    outline: none;
  }
  :focus:not(:-moz-focusring) {
    outline: none;
  }

This removes them only for mouse clicks in modern browsers.
moz-focusring selector removed it in older Firefox browsers. Just be sure to know witch browsers you need to support as legacy 🥔 browsers will still display outlines.

@povilasbaranovas This was quite interesting, thanks. The MDN article on :focus-visible does note that Safari support is lacking, though there's a polyfill using Javascript.

This gist is indeed ancient and incomplete.

I think nowadays you just need this:

button {
  all: unset;
}

It starts inheriting all the values like you'd expect, with the exception that:

• it still behaves like inline-block
• the text is still vertically centered

Lol. Never seen a more powerful one-liner in my entire career. Thanks, @fregante

This also removes the default outline from the button when it's focused which makes it completely inaccessible when using keyboard navigation. Be sure to style a custom outline. I tried using outline: revert at it seems to work OK in Chrome, Edge, Firefox and Safari, so for modern browsers I suggest keeping these 2 rules always together and use a mixin for that, so no one forgets.

@mixin u-button-reset() {
  all: unset;
  outline: revert;
}
