I wish there were a convention for sharing whole websites. Even a zip file containing an index.html plus images, css, other pages, etc. would be fine if browsers just supported it.
Yeah but that works through base64 data urls, which are clumsy. Epubs are zips of separate resources and that works great. We should have an equivalent for webpages and other similar documents—a digital-first competitor to pdfs. Or maybe just broader compatibility for epubs, such as first-class browser support.
