Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

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

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?

Icons have been part of applications since ages. Also most websites rely on icons. There were several ways to use them. First we used plain files then image sprites to reduce requests. Nowadays everyone uses icon fonts like font-awesome or glyphicons.

They are infinetly scaleable and styleable with css. The downside is they use pseudo elements for displaying. This is not only difficult to handle but also non-optimal for accessibilty.

A famous CSS-Tricks post brings SVG icons into play. The are also scalable and they behave like normal images. But we also want to have a sprite to not load any images seperatly and kill our servers and our sites performance. The proposed version is to create sprites with grunt or gulp using the symbol-trick. It's basically add every icon to a hidden sprite-image and give every icon an id-property.
