Design
It’s not that hard to make default fonts look good! Especially if they’re Apple System fonts.
Although there is some proof about dark mode being more energy efficient, it’s pretty easy to make light mode a little more “sustainable” just by adding some warmer tones, or avoiding white backgrounds.
WEBP images can save TONS of page weight and size.
I can use css for a lot more than I realized!
Development
Developing locally prevented me from consuming too much server space before the site was even up.
I wrote a BUNCH of functions to strip WordPress’ backend down, since there’s so much fluff and unused stuff.
I found a cool plugin to convert WordPress into a static site!
Instead of adding javascript to all pages, I only queue them in when that particular block is called!
