coding-bootcamp-testimonials-slider HTML, CSS & Javascript

hi everyone, this is the second time I am taking this challenge, the first time I did it then 3months ago I could not figure it the layout, I almost give up but seeing how people are trying their best every day to solve the challenge so I left for a while to learn HTML & CSS again from scratch, so yesterday I decided to pick it up again to my surprise I did what I could not do then, although am not sure about every step I used if it the best practice but I am open to feedback. And a great thanks to those that comment last on my last project, they recommend great resources which I will go through all after I submit these. thanks a lot to this great community, whoever that have found it has helped 90% on my journey of learning to code...
