I have this very odd issue when using Google Chrome Developer tool where it "looks like" it just zooms out when I try to change the device.
When I minimize the browser window and manually make it smaller it works fine as shown in the picture below:
The css changes and everything is good.
However when I use the developer tool to change it to say a mobile device nothing really happens:
Why is this happening?
I am using version 86.0.420.111
You need to add the following to your code inside your <head>
tag.
<meta name="viewport" content="width=device-width, user-scalable=no">
Without it the page would not be responsive on mobile.
