What is the difference between body table li and body > table > li?

Question

css

Hello. I'm learning CSS, I have a question about the differences in how these lines work.
For example, what is the difference

body table li{
    background-color: green;
}

from

body > table > li{
    background-color: green;
}

Answer 1

> is a selector that will only work on nested elements in a strict order.
body > table > li will not work for example on:
body table li ul li
body table li will work on
body table li
ul li
