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

Option 1: Command-line download extension as zip and extract

extension_id=jifpbeccnghkjeaalbbjmodiffmgedin   # change this ID
curl -L -o "$extension_id.zip" "https://clients2.google.com/service/update2/crx?response=redirect&os=mac&arch=x86-64&nacl_arch=x86-64&prod=chromecrx&prodchannel=stable&prodversion=44.0.2403.130&x=id%3D$extension_id%26uc" 
unzip -d "$extension_id-source" "$extension_id.zip"

Thx to crxviewer for the magic download URL.

/**
 * VH and VW units can cause issues on iOS devices: http://caniuse.com/#feat=viewport-units
 * 
 * To overcome this, create media queries that target the width, height, and orientation of iOS devices. 
 * It isn't optimal, but there is really no other way to solve the problem. In this example, I am fixing 
 * the height of element `.foo` —which is a full width and height cover image.

First, we need to figure out what the actual error is.  This is obviously frustrating given that the error message is intentionally truncating it.

1) SSH in to your node (various guides available for this if you're not already familiar with this).
2) Run this command (basically an Elastic Beanstalk wrapper command for npm install I found in a blog post [1]):
   $ sudo /opt/elasticbeanstalk/containerfiles/ebnode.py --action npm-install 2
3) Find the actual error message in the output from the npm install.

Once you know the error, it should hopefully be fairly obvious how to fix it.  I've run into two different errors over the last couple days on Elastic Beanstalk:

The first was a dependency that was using the new "^X.Y.Z" version syntax, which is only supported in Node >= v0.10.26 (whereas Elastic Beanstalk only supports up to v0.10.21 as of today).  The solution here was easy: hardcode a dependency version *prior* to when that dependency adopted to the new syntax.
