for example for this code: (I know about star but not '> *')
.row > * {
float: right;
}
or this one:
.row.uniform > * > :first-child {
margin-top: 0;
}

The > combinator separates two selectors and matches only those elements matched by the second selector that are direct children of elements matched by the first.

It selects all the elements where the parent is the one infront of > selector.

The * selects all elements, the .row > selects all elements where the parent is a .row element.
See the specifications.

The * selector is a wild card selector so will select all elements.
The > selector says "Only the next element of what you specify"
So > * will all select the next element no matter what it is.

The > selector in CSS is used to select child elements.
.row > * will style ALL elements within the parent class row.

">" means direct children elements. So that it will select all direct children of "row" elements.

is there any differenc between these two selectors in Styled-components? ">" vs "&" [duplicate]

What is the difference between '>' and a space in CSS selectors?

greater than sign(>) refers to the direct parent.
ampersand sign(&) also does refer to its parent.
const Container = styled.div`
> p{
color:red;
}
`
above equals to this ㄱ
const Container = styled.div`
& p{
color:red;
}
`
both versions will make the p tag, which is the direct child of Container, have a red font color....
is that wrong? if so, how are they different?
"parent > p" will apply only to paragraphs that are direct children of parent, while "&" will apply to all paragraphs located inside its parent, no meter the level. Putting "& p {}" is equal to putting "parent p {}".

CSS: How do I select a specific universal grandchild of a div?

I'm trying to select a specific and direct child of a specific and direct child of a div(I don't know how else to say that). However, in both cases, the elements could be anything so I need to use the "*" universal symbol to select these elements.
That may have been clear as mud, here is what I have:
.some-div>*:nth-child(2)>*:nth-child(1){
background-color: #d3fba9;
}
.some-div>*:nth-child(2)>*:nth-child(2){
background-color: #d3ffe9;
}
.some-div>*:nth-child(2)>*:nth-child(3){
background-color: #d3fac9;
}
As you can see I need to select the 1-3rd children of the 2nd child of a div, and apply style to them. Is it possible to do this?
Yes. The asterisk * is redundant since you have some specifier already in place for that particular element (the child and grandchild of .some-div.
.some-div > :nth-child(2) > :nth-child(1) - Selects the 1st child of the 2nd child of .some-div.
.some-div > :nth-child(2) > :nth-child(2) - Selects the 2nd child of the 2nd child of .some-div.
.some-div > :nth-child(2) > :nth-child(3) - Selects the 3rd child of the 2nd child of .some-div.

CSS: select all starting from n-th element

How can I select all child elements starting from n-th element? For example I have a div with 7 spans and I need to select all spans starting with 3-rd element, so 4,5,6,7 should be selected.
div>span:nth-child(2)~span should do the trick. The ~ General Sibling Combinator selects all following elements. The spec is at http://www.w3.org/TR/css3-selectors/#general-sibling-combinators
CSS2.1 selector
span + span + span + span {
/* matching a span that has at least 3 siblings before it */
}
CSS3 selector
span:nth-child(n+4) {
/* matching from 4th span on */
}
You can use
div:nth-child(n+3) {
// your style here
}
However, this does not specifically select elements 3-7. Instead, it excludes the first two elements. So it would also select elements 8,9, ...

trying to understand css3 syntax

msub > *:first-child:after, msub > * + *:before {
...
}
This is a code snippet from a css file I'm trying to understand.
msub is the element.
> This, greater than, applies to elements that is a direct child of msub
Do this for all elements of this type
:first-child Do this for all first children of msub
Why are they doing the > which is first child and :first-child which is first child?
> means "All children" not "first child".
:first-child means "The first child of its parent" not "The first child of the selector before the previous combinator"
<msub>
<a>
<b></b>
</a>
<c></c>
</msub>
msub *:first-child would select a and b because they are both the first child of their parent and are both descendants of msub.
msub > * would select a and c because they are both children of msub
msub > *:first-child selects only a.
msub - the element
> - target direct children of the parent element (not children of children)
* - get all child elements
:first-child - get first child element only
CSS works through selectors backwards so:
Get the first-child from all elements that are direct descendants of the parent msub.

Select all direct descendant dom elements regardless of type

I'm trying to apply CSS to any immediate child of a parent container element. How do I use CSS's descendant < selector to select any immediate child regardless of type (div / span / etc).
I assume you mean the child selector. It's >, not <.
.parent > *
That will select any element. You can of course use any other selector as the child (an element, class, id, etc.)
If you are in SCSS then
.parent {
& > * {
}
}
