Ever think high contrast was just for bold designs? I used to avoid dark colors on charts, worried they'd look too heavy. After a friend with color blindness pointed out my "subtle" green and gray combo was a muddy mess to him, I switched to black lines on white with pattern fills. The clarity for everyone was worth dropping my muted palette.

Yeah, mine found a typo I'd read over a dozen times.

Those old sign painters clearly never wasted hours doomscrolling through Google Fonts (lucky them).

Remember my first web page with blinking text and a rainbow background. My cousin said it gave him a headache and I learned fast that simple is better. Sticking to basic fonts and high contrast colors actually helps people focus on the code itself. What did your friend suggest you try instead?

Grid-template-areas was a game changer for me too. I still use Flexbox for smaller bits inside those areas, like a button row, which is where I see @jade618's point. My old float-based sidebar code was a mess of clearfix helpers. It felt like fixing a pipe with duct tape when you finally find the proper wrench.
