I am moving this gist to a github repo so more people can contribute to it. Also, it makes it easier for me to version control.

Please go to - https://github.com/praveenpuglia/shadow-dom-in-depth for latest version of this document. Also, if you find the document useful, please shower your love, go ⭐️ it. :)

Shadow DOM

Heads Up! It's all about the V1 Spec.

In a nutshell, Shadow DOM enables local scoping for HTML & CSS.

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git

This is a temporary fix for a problem running Gitlab on Proxmox 4.1 inside a LXC container. Symptom: UNIX sockets created inside containers get wrong permissions. This seems to be related to AppArmor and the Debian kernel used by Proxmox. See this thread on the Proxmox forum for details.

Run apt-get install inotify-tools if you haven't installed inotifywait yet.

Place the first file in /usr/local/sbin/fix_gitlab.sh and make it executable: chmod 755 /usr/local/sbin/fix_gitlab.sh. Edit etc/rc.local to include it during boot.

Polymer 1.0 : Custom elements

Simplest possible workflow

Minimal steps required to create a custom elemenet in Polymer 1.0, without any aid from tools like Yeoman and Gulp.

I have used the Quick tour of Polymer as a reference.

Prerequisites

Install Node.

The reason you might not be able to remove the Open Sans font that Wordpress >= 3.8 adds to the frontend is that quite a few WP styles and scripts list 'open-sans' as a dependancy when being registered and enqueued. When you remove the 'open-sans' style the other plugins dependant on it will not load. So you just need to deregister WP's open sans style and register your own, with a false value for the src like below.
