that sounds like a not-great designer, tbh. Which happens often, what I usually do is not take everything in the design at face value: 28px is actually 32px, which is 8rem, which is `w-something`.
It really needs to be 28px this time for some sorta-legit reason? Fine, add a semantic class (or id) for it that's not part of your tailwind framework, kind of dropping down to "usual" CSS
An actual inline style would suffice in this case. Before v2.0, if you want anything other than `top: 0`, it was recommended you do it in the style attribute: `style="top: 20px;"`
