You need to read up on css selectors
 
My hard confusion is with the below lines:

***** "#ires ol li" *****

- when to write this way?
- what `#` stands for? Looking at the source page I saw `ires` is one
id. -- when I need to use such `#` and when `.`?

#foo finds an element with id foo whereas .foo finds an element with class foo. Which one to use depends on the markup.
 
- Is there any other operators like `#` and `.` when using css?


Yes, there are a whole bunch, such as the pseudo selectors (:not, :nth-child), attribute selectors etc.

https://developer.mozilla.org/en-US/docs/CSS/Getting_Started/Selectors

has fairly exhaustive info
