How to check website mobility?

Question

Mobile development

Hello, is there any thread service for checking the site in different mobile resolutions?
I’m watching the web browser on Yandex and I don’t see a match, I first went to the site from my phone, I have a resolution of 360x640, the site is displayed normally, the user has 480x853 and the menu didn’t fit, like this, the resolution is larger in width, but the menu didn’t fit, and CSS configured correctly.
Further, in the mobile version, the header is fixed and translucency is added by the JS script, it works fine on my phone, but in desktop chrome, when viewing mobile pages, translucency does not work. The www.responsinator.com
service also does not work correctly, how then to configure CSS and scripts for the mobile version if the display is different everywhere?

Answer 1

The Yandex counter records and transmits only actions, and when playing back, it tries to repeat the same actions. So you should not rely on the correctness of its display.
You can check adaptability in different ways, ranging from responsive mode in chrome to physical devices.
