    CSS is amazing. I am sad that it seems so undervalued at times. Many of the most senior programmers I know can't grasp it. If you can, know that you are amazing. And there are jobs for you. Try design systems. It welcomes you! 💜💜💜

    sometimes it feels like i’m not capable of higher-level programming since i tend to default to css

    TIL: You can use "optional chaining" in JavaScript, a concise way to access "values through connected objects when it's possible that a reference or function may be undefined or null." Looks like: obj.mightBeNullish?.plzDontBork

    Don't stop after HTML and CSS, yes Javascript is overwhelming and tough. Go bit by bit, but don't quit there. I made this mistake twice, you shouldn't.
