Mobile responsiveness, the phrase that’s become a service offering rather than what used to be techy industry jargon used by professionals. If you’re website isn’t optimised for mobiles, then you’re putting yourself at a serious disadvantage.

Beside the point – as a website developer it is inherent in our day-to-day we test all the sites we build for their responsiveness to a whole array of devices. I know, I know, there are a thousand tools online that will test them for you, a bunch of Chrome add-ons that can automatically resize your window size to the same dimensions as whatever device.

However (and true to ‘you learn something new everyday’) I found out that Safari’s developer tools has an inbuilt functionality that will render any website to whatever screen size /device you are looking to test. I found it much easier to use than any of the other tools, or browser extensions I’ve used before and decided I had to write up this short blog post right away to tell everyone about it!

Okay, so down to the good stuff.

Step 1:

Make sure the ‘Develop’ menu item is enabled in your Safari browser. You do this by going to Safari > Preferences (or if you’re lazy like me, just hit Command + ,)  and then going to the ‘Advanced’ tab and checking the ‘Show Develop menu in menu bar’ option.

Step 2:

Go to whatever website/page you’re wanting to test the responsiveness on. Go to Develop > Enter Responsive Design Mode (or again, if you’re lazy, just hit (Command + Option + R). Your window will do some magic hoo-ha and ta-da you can see your website in a bunch of various different screen sizes.

The great thing about this tool is that it allows you to also do cross-browser checking to make sure all your snazzy scripts and transitions are all working as intended.

I know I am probably missing out on some great tool that EVERYONE else is using but for me, so far, this one takes the cake!
