Hey everyone. I want to enable something like in the ‘uploaded’ picture.
I will be using it on testimonial page. Does anybody know how to implement it using a plugin or html code, if any.

Don’t consider the background. I want to know how to make that box thingy with testimonial and testimonial writer below it, just like in the image.
