I'd recommend just using plain JavaScript. There's a great blog article by Githubs engineering team about how they removed Jquery from their front-end and now rely just on vanilla JavaScript: https://githubengineering.com/removing-jquery-from-github-frontend/ https://githubengineering.com/removing-jquery-from-github-fr... Also, don't be afraid of embracing multi page app versus going for a single page app (they're largely overrated). For front end CSS design framework, I'd recommend something like Bulma. Very easy, modern and CSS-only. You can learn it all in less than an hour.
