Two of my team members were trying to make a website responsive for over an hour. They tested everything. They checked the JavaScript, checked their CSS media queries, tried everything but it just wouldn't work on mobile browsers.

So as usual they decided it was "impossible" due to "WordPress constraints" and told me that it would work on the browser but not desktop.

I just added the meta viewport tag. It literally took 10 seconds. It worked.

I hate people who give up easily. Just hate it.
