I would like to use this functionality to add a section for customer testimonials on my website www.studiooncloud.com. Can you guide on steps to follow? Should I first insert a gallery block & then copy this code?

Insert Code Block > Paste all above code

Hi I really am desperate for help on this issue.

On pc the website looks fabulous, exactly the way I wanted it to be. 
Problem comes up on mobile. 
www.ibisette.com/portfolio/portraits for example, all portrait-oriended photo's in the carousel show a lot of blank space on both left and right side of the image as you can see on the screenshot below. 

I would like to have the carousel to be taller so that pictures in both landscape and portrait mode be seen clearly. (I have absolutely no problem with how the landscape mode pictures are displayed now, it's great. It's just for the portrait mode that the blank space is way too big. I would love it to look a little more like the paint job I did below: 

Is there anyone who could help me write a little bit of code to fix this issue? 
I have disabled the autoplay.
