post "slide" to the right when embedding tweets or Instagram in WordPress

I am using Sahifa wordpress theme.

When ever I embed tweets or Instagram pic in a post the post page slide to the right and return to the center.

it is happeing only on mobile and only in the post page

The author told me to add this code to the “Global CSS” section in the (Theme Settings page >> Styling):

    overflow: hidden;

it didn’t help.
