Wappalyzer (https://wappalyzer.com/) tells me they're using Bootstrap (http://getbootstrap.com/) (probably customized a bit). HTML isn't very difficult (just another markup language) and if you're not inclined toward design (I am also not) there are a plethora of CSS frameworks to choose from (like Bootstrap) that will get you up and running with something not completely ugly. Personally I like Bulma (http://bulma.io/) right now which showed up (I think as a Show HN) on here a while back. Currently using it for a project and I'm enjoying it.

Really my design sense isn't great, given time I can hack together something with bootstrap, but I do think I lack the designer training and probably instincts

Same here. I recommend making friends with some designers or looking around at pre-customized versions of Bootstrap. I also spent some time looking for this: http://jgthms.com/web-design-in-4-minutes/ One of my favorite sites for this type of conversation.
