smartphone to horizontal position

just activated a breakpoint in my test website at 600px, 1 image per slide, and it works
What have you set as breakpoint?

checked your source code, there is no breakpoint activated at all

Hi, thank you for you answer. I know, the dsactive, because they did not work well ... I'm going to activate them, in a way that you can verify, but first I wanted to ask you a question.
* Exactly how should you configure the breakpoint ?: (I need that when the Smartphone is in Horizontal position, or the Tablet, Ipad 12.9 inch, this vertical position, show more slides, without looking much bigger as it happens now) .

greetings thank you
Michael

each breakpoints is set for 1 resolution. For each one you can set the number of slides to show. I can not give you more explanations than setting a resolution and a slides number ...

I need to know exactly what resolution in px write for the smartphone in horizontal position and ipad 12.9 in vertical position.

why shall I know all resolutions ? this is something that you can ask on google or just test
