I decided to take a WordPress class through Continuing Ed. This website may change, although I want to keep it simple. I like having more control than just a Facebook page where my videos get blocked by a “gotcha” copyright algorithm.
After struggling with plugins, I settled on Envira Gallery and MetaSlider, plus Google Fonts. I used WP Smush to set a maximum 1280 pixel width so that photos load quickly — but bear in mind they look and print better from full size. The main gallery on this page was re-smushed to 2560 pixels, and there is a page of selected photos at full size. There are still issues to be worked out with the Home page and the Header video working on mobile devices. I could mess with the code on display size. But video backgrounds generally are not available on mobile devices so it is replaced by a static Media Poster image. (Users are not happy if you start a video streaming that consume the monthly traffic, so this is considered as a best practice in web development.)
