#Building a Responsive Design is Tough to Test - Responsizer.JS Makes Measuring Easier
I choose to build my latest web site in a totally responsive manner to work on laptops, iPads, iPhones in portrait and landscape. Many of you do it, but testing your media query rules is a grind. What to do? Send it up to the server and load it on device? Are all the devices at hand? Is the server ready? Is the server off-limits to changes?
Instead simply drop into your website the Responsizer.JS library letting it show you common device widths as you resize your laptop browser. How does it work? This library is so easy and useful you’ll wonder why you haven’t had something like this already.
Include the file “Responsizer.JS” into your index.html and it's assumed that jQuery is loaded and available too.
The library is in fact a simple piece of Javascript code. It’s a self-invoking function that hooks onto the window’s resize event. At the same time it creates a display box centered along the top of the window. Watch it tell the window’s width and height as the browser reports it.
As you resize your laptop browser (Chrome, Firefox, Safari, etc.) you’ll see the library reporting the width and height. When a typical mobile width is reached (1024, 768, 480, 320) it changes colors highlighting the significant breaking-point. This guidance helps you conveniently test your responsive design on your development laptop without dragging a cellphone or tablet into the mix.
