My personal site does not have any JS, but honestly at this point what I really want is an app where I can edit the page and see the markup and then press a button and it will generate and upload the content to my website. I tried to finagle gitlab into it (since they offer free hosting and CI) but I haven't gotten the last step to quite work yet. Would be awesome to be able to work in both of line mode or through my Chromebook, and sync everything with git.
