////////
// The vm module lets you run a string containing javascript code 'in
// a sandbox', where you specify a context of global variables that
// exist for the duration of its execution. This works more or less
// well, and if you're in control of the code that's running, and you
// have a reasonable protocol in mind// for how it expects a certain
// context to exist and interacts with it --- like, maybe a plug-in
// API for a program, with some endpoints defined for it that do
// useful domain-specific things --- your life can go smoothly.

Strictly Frameworks

• Mobiledoc - github.com/bustle/mobiledoc-kit - framework to build editors with a standardized JSON structure
• ShareDB - github.com/share/sharedb - framework to sync any JSON document using operational transforms, add real-time collaborative editing to anything else
• Bangle.dev - github.com/bangle-io/bangle.dev - toolkit built for building editors, based on prosemirror

Abstracted Editors

These use separate document structures instead of HTML, some are more modular libraries than full editors

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

READ FIRST

This is outdated information, though the concepts are valid. A script implmenting these concepts for OpenConnect 8 on Ubuntu 18 (bionic) and 19 (eoan) is available

Building OpenConnect 7 on Ubuntu 14 (trusty) and 15 (vivid)

The steps in this guide are available as an autobuild shell script

What CSS best practices should I follow ?

HTML best practices Depends. How far down the rabbit hole do you want to go ?

Just need something to look good : use a frontend framework like foundation or bootstrap, won't learn much about CSS. Short list of Front End Frameworks

Surface level : work general to specific. Comment the sections of the CSS. Use a reset or normalizer. Work on patterns, use classes over IDs for reuse. CSS Resets - includes normalize.css Don't have links for the other parts. see below

Little bit deeper : Look into BEM or OOCSS. Those stand for Block Element Modifier and Object Oriented CSS. Two popular methodologies for CSS. Also SMACSS.
