03/12/2025, 10:28 AMHi, what rule-set do you use under the hood to categorize devices into deviceType (mobile, desktop, tablet)? I couldn't find anything on this in the docs.
For context: I was planning to use CSS min-width / max-width to show sections of a page based on device, but I'd need to align them with GB definition, otherwise the stats won't make sense. I'm trying to avoid splitting the test into multiple test - one per deviceType.

Copy code
function getBrowserDevice(ua) {
const browser = ua.match(/Edg/) ? "edge" : ua.match(/Chrome/) ? "chrome" : ua.match(/Firefox/) ? "firefox" : ua.match(/Safari/) ? "safari" : "unknown";
const deviceType = ua.match(/Mobi/) ? "mobile" : "desktop";
return {
browser,
deviceType
};
