I see your point, but it's also mainly going to be seen on desktop, as I'll send it to recruiters as a CV."
I wouldn't make the assumption that recruiters are using desktop.
Personally, I write on desktop. I read on iPad.
I wonder if something like SquareSpace, etc. or else something more tailored to designers' portfolios might serve you better? Lots of places where you can get nice portfolio designs with no hassle or programming.
The company I work for makes educational software. We use Squarespace. We don't bother to "roll our own" marketing website with custom JS, etc. We put that effort into our app instead. We have a designer who drags-and-drops, and we are fine with that!
A good friend's sister is an artist. As in, canvas, print, sculpture, multi-media. She has a nice site, where she shows her portfolio and her globe-trotting travels to art fairs and shows. I know she doesn't know a whit of JS or HTML. She uses Wix. Similar to Squarespace.
Both SquareSpace and Wix seem to do a pretty decent job of adapting between desktop and mobile, with no technical knowledge needed. I think SquareSpace may do a better job of adapting to different screen sizes, where Wix is more either/or desktop/phone. But may just be the template that my friend's sister choose. It doesn't adapt when you make your desktop page narrower, but it has a different phone-friendly layout, and fits itself to a touchscreen tablet, if a bit tiny print...
Hang in there, it looks like you have great credentials! I suggest you don't let trendy web stuff get in the way of showing them off!
