Google Chrome, as well as, Safari and Firefox have responsive design modes that allow you to test your site for responsiveness.

In many browsers you can simply adjust the size of the window and the browser will respond. However, this is going to change the size of all the tabs you are working with. The responsiveness tools allow you to test a specific site, while continuing to browse as normal on the other tabs.

Google Chrome Developer Tools

If you are a Chrome user you can get to the responsiveness tool by following this path:

Custumize and Control Menu (top right) > More Tools > Developer Tools

Once developer tools opens on the right, look for the mobile view icon at the top of that section of the window next to where it says "Elements" and click.

You will than see a toogle drop down menu in the center that says "responsive" unless you have previously changed it to a specific device view. (images shows Galaxy S5)

There is a feature that also allows you to rotate the display, as if holding a mobile device in the horizontal position for a wider view.

I hope this helps all you Chrome users here at WA!
