If you ever find yourself in such a situation again, Tiny Helpers might have just the tool you’re looking for.

This talk is about how Chrome turns web content into pixels.  The entire process is called “rendering”. We’ll describe what we mean by content, and what we mean by pixels, and then we’ll explain the magic in between. 


Twelve Days of Front End Testing

There are so many different tests we need to be running on the front end, it’s hard to work out what your need to test for and where to start.


Asynchronous vs Deferred JavaScript

JavaScript is considered a “parser blocking resource”. This means that the parsing of the HTML document itself is blocked by JavaScript. When the parser reaches a <script> tag, whether that be internal or external, it stops to fetch (if it is external) and run it.

CSS frameworks have been around for a while and they have gotten extremely popular in the front-end development scene. These frameworks provide snippets of code you can just copy and paste in your website to craft the whole layout and UI.
