use class names to help userstyles

tailwind is cool but arbitrary meaningless class names is cooler!!! i dont think we will actually use the class names for our own styling, lets stick to tailwind. but as a userstyle developer myself it is way more convenient to style on classes than a bunch of hacks like &div>div:nth-child(2)+div[style*="color: #eee"] > *:not([style*="display: none"]):is(div,span)::before
