    Extended details and known issues

    Additional detail and explanation of the esoteric parts of normalize.css.

    pre, code, kbd, samp

    The font-family: monospace, monospace hack fixes the inheritance and scaling of font-size for preformatted text. The duplication of monospace is intentional. Source.

    sub, sup

    Normally, using sub or sup affects the line-box height of text in all browsers. Source.


    By default, Chrome on OS X and Safari on OS X allow very limited styling of select, unless a border property is set. The default font weight on optgroup elements cannot safely be changed in Chrome on OSX and Safari on OS X.


    It is recommended that you do not style checkbox and radio inputs as Firefox's implementation does not respect box-sizing, padding, or width.


    Certain font size values applied to number inputs cause the cursor style of the decrement button to change from default to text.


    The search input is not fully stylable by default. In Chrome and Safari on OSX/iOS you can't control font, padding, border, or background. In Chrome and Safari on Windows you can't control border properly. It will apply border-width but will only show a border color (which cannot be controlled) for the outer 1px of that border. Applying -webkit-appearance: textfield addresses these issues without removing the benefits of search inputs (e.g. showing past searches).
