For me, when I'm working on a layout (I'm not a designer at all) it's quicker for me to parse words that describe what I want, than to type out style="border-radius: 5px; border: 1px solid #2563eb; background-color: #3b82f6" Personal choice obviously, but I work with frameworks and components if I'm doing frontend stuff, so having things as a single name for something that is consistent across everywhere I use it makes it easier for me. It's not for everyone, and that's cool.
