pyquery allows you to make jquery queries on xml documents. The API is as much as possible the similar to jquery. pyquery uses lxml for fast xml and html manipulation.

Slingcode is a personal computing platform in a single html file. You can make, run, and share web apps with it. You don't need any complicated tools to use it, just a web browser. You don't need a server, hosting, or an SSL certificate to run the web apps. You can put Slingcode on a web site, run it from a USB stick, laptop, or phone, and it doesn't need an internet connection to work. You can "add to home screen" in your phone's browser to easily access your library of programs on the go. You can share apps peer-to-peer over WebTorrent. It's private. You only share what you choose.
Everything is kept in the browser's localstorage system.
It's written in Clojurescript with a bunch of dependencies, but the output is a single HTML page that you can drop anywhere. Probably easier to download it from the website (as recommended) and drop it someplace.

A super easy to use, super lightweight JavaScript library for implementing autocomplete in input form fields. All you need to do is load the CSS and JS, and supply a list of possible options to pick from. Very flexible.
A Python module that tries to make parsing HTML as easy to do as Requests makes HTTP requests easy. Written by the same developer, in fact. Built on top of Requests, so you don't have to juggle both. Python v3.6 and later only. Full Javascript support(!), CSS selectors, XPath selectors, user-agent spoofing, automatic redirects.
How to use JQuery to change fonts on the fly on a web page.
A telnet client written in HTML5.

A collection of JavaScript and CSS progress bars that can be incorporated into websites. Creative Commons.
Bootstrap is a web development template from two folks at Twitter which aims to make designing websites easy and elegant. Designed to be device-responsive, so the CSS adapts based upon the browser and platform viewing a site. There is a compiled and minified version that you can download, as well as a version that has all of the code in its basic form. There is even a web-based customizer you can use to tailor what you want the page to look like before you start developing it.
