Sliders are making me question my sanity

Hi friends. Sliders, is there a good resource for light customization and trouble shooting?

I’m trying to build a portfolio site with content contained in lightly modified sliders. In a dream world, the images would be 3:2, take up 85% of the VW, so the edge of the next image is visible. For navigation the page numbers would display 10px below the images on the bottom left, and the arrows would sit outside the main image margin.

It’s been three days of fiddling and I cannot figure out how to get the sliders to behave in any kind of rational responsive way. Images come off the page, the pagination disappears, arrows show up in the wrong places. Is there a simple tutorial for this somewhere? Or maybe a guide to common errors?

It feels crazy to me that displaying images is so difficult.
