According to Developer Tools the above CSS should be working but apparently it is not. There is no padding, border, border-radius, etc., on the search form.
I’ve tried to use more specific selectors but nothing seems to change the input from being the default one. (although it is stretching to be 100%)
Sorry I can’t show you the site it’s in development.
Thanks Stephen. Actually the input[type=“submit”] was elsewhere in the CSS.
It was because I was viewing on webkit browsers on a Mac.
For some reason, with HTML5 they will style the element to appear like native Mac controls – “-webkit-appearance: none;” rule prevents the default styling.
