I like the approach of a small, fun task as &quot;extra credit&quot;. But how do you smoothly bring that up in the interview? I guess if you&#x27;re being asked about CSS technical details, you can mention you built this last night and ask if they&#x27;d like to see it. But I&#x27;m pretty sure due to nerves, I would make that really awkward. Like I&#x27;d answer the phone and shout &quot;LOOK AT WHAT I MADE!&quot;
