I've started to really get into coding using HTML5 and CSS3 over the past 3 weeks and even started on my own project.
I've come across people saying "MOBILE FIRST!!" a lot along the way, and I've been looking into it and found out how to do it using media queries.
I use the Atom text editor to write my source code, and view my html file on chrome.
My question is, what program or extension do people normally use to view their code on different device types?
Many thanks!
Dan
