Browsers

Friends, tell me about the layout.
DELETED I
open it in chrome - great, but in firefox there is a huge horizontal scroll. I admit that I will not see the obvious, I myself am not a typesetter. If it is possible more in detail a way of the decision of a problem. Thank you!

Answer 1

At a resolution of 1920 x 1080 - nothing is visible.

Answer 2

To begin with, my .b-carousel__wrapper has a width of 2200px, that is, it is either manually considered crooked, or a bug in the carousel.
If this makes you happy, then at a monitor resolution of 3840x2160 in Firefox, horizontal scrolling disappears) As well as vertical, however)
