> Taking into account the priority in CSS, I have to compete in SMS with styles as https://github.com/mozilla-b2g/gaia/blob/master/shared/style/input_areas.css#L190, so sometimes it's more than tough to achieve our goal with 'classes' or a different structure. Remember we are 'tied' sometimes to the benefits/drawbacks of Building Blocks.
`form[role=search]` is less specific than a classname.
