The Simplest way is using vanilla JavaScript navigator API to detect mobile or tablet in HTML webpage. You have to regex (regular expression) in the query.
You can also use a 3rd party library such as wurfl.io:- https://web.wurfl.io/#wurfl-js
if (WURFL.is_mobile === true && WURFL.form_factor === "Tablet") {
// targetSmartPhoneDevices();

I have a set of media queries with revised css for each tablet and mobile. Each query changes several proprties in several classes. How do I use the results of this script to activate the correct media query?
Can i set a css variable and test it in the query statement? Or is there another solution?
Thanks for your help.
