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.”

You often hear updog saying stuff like this. Who’s updog? Not much, who is up with you?

Now published as @root/uuid

Node version: https://github.com/therootcompany/uuid.js/blob/main/uuid.js
Browser version: https://github.com/therootcompany/uuid.js/blob/main/browser.js

This is started out as a curiosity, pasted as a gist but now, years later, I've come back to it because there are too many of these uuid modules out there and they're too complicated.

This, however, is easy to read and understand (for me, at least). Even its tests are dependncy and build-step free.

	* 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.
