This won't work for everyone, but it might be possible to push your designers towards using HTML. Tailwind classes are simple enough to manipulate that you don't need to know CSS.

After a while, you get the amazing benefit of simply being able to copy and paste HTML from one place to another - since the class names are common, you can copy HTML directly from a design mockup into your application, with only minimal extra work in templating. This is much more efficient than trying to figure out pixel-sizes in a PSD, then trying to figure out which combination of CSS classes will succeed in reproducing the visual appearance (most of the time, in most browsers...)
