From: https://www.jesgs.com/blog/2017/12/18/deploying-from-github-to-vps-using-travis-ci

Recently, I spent around 14 to 16 hours learning all of the necessary steps to getting an existing repo set up with Travis CI to run unit tests, and then once successful, connect to a remote server that isn't a PaaS (in this case, Linode) and then proceeds to use Git hooks to do post deployment things.

Starting with your local machine and you have your project already checked out from Github.

Setting Up

• Assuming you have Ruby (at least 2.3.1) installed, run gem install travis. This installs the Travis CI command-line tools. We're going to use these tools to encrypt RSA keys that Travis will use to connect to your remote server.
• This tutorial also assumes that you have a working repo and a Travis-CI account set up.

scrollIntoViewIfNeeded 4 everyone!!!

This gist provides a simple JavaScript implementation of the non-standard WebKit method scrollIntoViewIfNeeded that can be called on DOM elements.

Usage

Just use the code in index.js in your app or website. You can see usage in the test page test.html.

The parent element will only scroll if the element being called is out of the view. The boolean can force the element to be centered in the scrolling area.
