I've been customizing my default stylesheet for accessibility. I've modified my buttons so that they're very readable on desktops using all browsers I've tried. But when I load my forms from my phone, the buttons take on a weird gradient that gives a rounded appearance to the button. This is not what I want, as it's much less legible. Anyone know how to turn off this default for mobile devices ... or at least where the style is coming from? I don't see it anywhere in my CSS. Thanks!
