Testimonial slider using React | SCSS

What are you most proud of, and what would you do differently next time?

I got to use new accessibility techniques such as role and aria-roledescriptions and it's nice to play with animations sometime :)

What challenges did you encounter, and how did you overcome them?

My html structure at first was not a good one for making a carousel, I got help from community and read guides on making a good accessible carousel slider. w3 was a good source: Carousel guide

I used absolute positioning for buttons but got recommended to switch for grid layout and I went for that.

What specific areas of your project would you like help with?

My grid works alright but not sure of how effective I have used rows to move buttons for different screen size. For some reason on desktop preview using mobile the buttons get a little displaced I can't figure out why, otherwise it works alright for normal preview.

I could get a little help on buttons focus state it seems the overflow:hidden is hiding the outline too.
