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 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
