I built a website using materializecss framework for responsive website. I made it responsive with columns (.m4.s12) etc but what I found out is that my website is responsive only on resize.
If I load it on my devices (or simulate in desktop browser) - mobile or tablet, the website is not responsive at all.
I tried to look for some advices but couldn't find any similar issue. This is the website.
Do you have a <meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=yes"> tag in your <head>? This is a good practice to ensure mobiles and tablets work as we've come to expect.
