How to make background image slider and sircle images in bootstrap?

Question

css

Tell me please! I'm a beginner in layout, I say right away)
There is an embryo of landos (lifejacket.ru). It is necessary to implement a background slider of the first screen with a fade type manifestation of only 2-3 images, and an image slider in circles from left to right, also without arrows and other controls.

I have already tried very hard to do what is suggested in the top, but nothing comes of it. Especially the fact that through java.
Maybe someone knows a simple implementation so that even I can understand? Like "yes, put this here and that's it."
