wpforum on "[Plugin: Jetpack by WordPress.com] add left margin to image description Carousel mobile view"

How can I add left margin for mobile view of image description in Carousel? On the desktop the text is centered on the page, left aligned.

Do I need to add HTML code in Description or make changes to jetpack-carousel.css?
