Could you please enable right click? Otherwise I cant check devtools.
Hi Mehtaz. Do you know about existing of browser menu, where you can run dev tools without right click :)
Use this custom CSS in your custom.css file
CSS is not required for this, this setting is in every addon (Advanced Tab). But in OP case, this is not required at all.
In each addon there is margin settings (Style Tab) for different screens.
Mehtaz, you continue to provide a strange, and at times even harmful support, and do not learn anything. Take SP Page Builder and make at least one site yourself, then you can provide a more qualified support
