You should estimate how much time it would have taken a human
Every browser has an inspector that can show you which element is causing overflow. You walk through the tree, find the offender, and add min-width or overflow. Zero tokens, just like in the old days!
Now, granted, because the garbage LLM code he’s working with has CSS inside HTML inside JavaScript inside Python (I wish I were kidding), finding the styles in his codebase might’ve taken a minute. But even then!
And to my surprise it was.
This would’ve take a frontend dev 10 seconds to deduce and another 10 seconds to confirm.
So if you’re doing web pages, learn CSS.
Generally, if you’re doing something that directly involves X, learn how X works.
ADDENDUM
In most jobs, you’re going to be involved in only a few distinct technologies, learn those well and life is going to be easier. And most are transferable to the next job.
