Bring any page you have made (hand-built, Bootstrap or Vue) and get it ready for real people: check it works for everyone, then put it online. No new framework: it works the same on every page.
Check a page works for everyone, then download it, check its files and paths, and publish it.
Check a page works for everyone: pictures described with alt, headings as the page's outline, labels joined to their boxes, links that say where they go, readable colours; then test it with a classmate.
A website is a folder of files: download the page and every file it uses, make every path relative, test the folder on your own computer, then publish it to a host.
