Minimalistic but perfect custom scrollbar plugin  Demo

perfect means...

• There should be no css change on any original element.
• The scrollbar should not affect the original design layout.
• The design of the scrollbar should be (nearly) fully customizable.
• If the size of the container or the content changes, the scrollbar size and position should be able to change.
• New! It should work with vanilla JavaScript and major tools like NPM or Browserify.

Intence is a new UX concept and a JavaScript library which reflects the scrolling state in a simple and intuitive manner. It highlights the scrollable area depending on the scrolling amount, thus efficiently explaining to a user what exactly can be scrolled, and is there much to scroll. Intence is suggested as a scrollbar replacament for a general designation of a scrollable area. The library is written in vanilla JavaScript and has no dependencies.  Demo

A minimal, UI-focused programming language for web designers. With uilang, you write your code just like plain English, straight into your HTML using a <code> element. uilang's logic relies on manipulating classes on HTML elements and using these classes in CSS to show, hide, animate and transform elements when a click occurs. This simple logic lets designers create most of the typical user interface behaviours: tabs, popovers, overlays, sliding menus, etc.  Demo

In the eighteen years that I’ve been doing Web development, a lot has changed. We started out creating HTML pages to present static information to our users. We then used classic ASP to get database data and incorporate that into our pages. To use both of these technologies, we had to know a lot about HTML, CSS, and JavaScript. Along came .NET and we started rendering everything on the server-side. We forgot a lot about HTML, CSS, and JavaScript as Web Forms wrapped up a lot of that for us. Web Forms’ architecture closely mimicked the way developers created desktop applications. This was great for helping developers move to the Web, but unfortunately hid a lot of the power of the Web, and also tended to be a little slow.
