Discussion on: What's the difference between CSS `s1 s2 {}` and `s1 > s2 {}`, and how do they cascade?

[Ben Read]

s1 s2 {…} will select any child of s1, where as s1 > s2 {…} will select only direct children.

[Calin Baenen]

Then how come s1 > s2 still removed the ::markers from the li despite no-markers being applied to the ul?

[Ben Read]

Because of the space between the declarations. Take a look at this for a comparison. codepen.io/endymion1818/pen/WNMMpwO

But there's no > there.
Or is that only required when two tag selectors need to be disambiguated?

[Ben Read]

Yes you're close, the space signifies selecting a child in this case.
