Which of the following selects all elements with the class footer that are inside of divs?
A. div {
.footer {
...
}
}
B. .footer div {
...
}
C. div > .footer {
...
}
D. div .footer {
...
}
D. div .footer {}
The correct answer is D. div .footer.
Option D, div .footer, will select all elements with the class "footer" that are inside of divs.
The correct answer is option D. "div .footer" selects all elements with the class "footer" that are inside of divs.
To understand the concept, let's break down each option:
A. "div {.footer {...}}" is not a valid CSS syntax. A class selector (.) should not be used directly inside a tag selector (div).
B. ".footer div" selects all div elements that are descendants of an element with the class "footer". This means it will not specifically select divs with the class "footer" itself but rather divs inside elements with the class "footer".
C. "div > .footer" selects all elements with the class "footer" that are immediate children of a div. The ">" selector is used for direct descendants, not for elements inside divs.
D. "div .footer" selects all elements with the class "footer" that are descendants of a div. Here, there is a space between "div" and ".footer", indicating that any element with a class of "footer" inside a div (direct descendant or nested) will be selected.
To summarize, if you want to select all elements with the class "footer" that are inside divs, the correct CSS selector is "div .footer" (Option D).
