Feels like the “device emulation” thing in chrome dev tools is inconsistent, meaning it produces different layouts even at the same resolution compared to responsive, or just minimizing your browser window and resizing manually. In your experience, is the device emulation accurate? What’s your go-to method for actually reproducing what it will look like on your phone?
I use the Chrome tools but ultimately I just use my phone. I do recommend looking at other phones as well - my newer Samsung definitely has more real estate than my buddy’s older iPhone!
