The days of writing pure html or using an html editor for a personal site are long gone. Today you download (free) html and css templates and use those. If your site is in wordpress there are lots of free wordpress templates available. Better ones cost a little bit but the free ones should be good enough.
People keep saying that, and I know it's largely true, but I've been doing straight html with a really simple editor for years for my own personal site. I've considered doing a conversion to CSS or something, but it would be a huge amount of work, that I'm just not interested in. My site is primarily for my own enjoyment in any case. If anyone besides google bots even know it exists, that's news to me. :-)
