My website is https://themmitchellgroup.com. When I view the website on my PC via Chrome or any browsers, it looks perfect. But when I see same website on a mobile device (smartphone), the Chrome browser make it looks weird and blurry. I’m using Joomla 3.10.3 with Helix Framework 2.0.6.

I am able to open all of the tabs using my laptop and all the pages are clear. Once I used my cellphone, the home page was clear, but I was unable to open any other tabs and when I click to try to go to another tab, the screen is blurred and I cannot see a list of tabs. Please help! Thanks.
