Ah this is definitely something I’ve wanted to talk about, as I’m a strong believer in making simple webdev accessible to the layperson! But the short version is:
My site is a static site hosted on Netlify, I use the Eleventy/11ty SSG to make creating my webpages much simpler
and the design for my site is a customised version of bootstrap 5—by taking advantage of the 11ty SASS Plugin & the bootstrap SASS source code, I’ve made two custom themes for bootstrap (inspired by the solarised colour schemes bc I like them ^_^)! There’s not a lot to the design beyond that, my primary goal is to make something easy to read so I try to keep it simple & just chop the occasional corner off for some visual interest haha
