Trello CSS Guide

“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”

	* 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.
