How Can I Select nth Child Elements Without Knowing the Parent?

Universal Child Selectors: Selecting nth Child Elements Independently of Parent

Problem:

Selecting specific child elements can be challenging when the parent element is unknown or has a dynamic name. While :first-child and :nth-child selectors exist, they only target children within the scope of a specified parent.

Question:

How can nth, first, and last child elements be selected without knowing the parent element?

Answer:

Contrary to common perception, :first-child and :nth-child selectors do not require a specific parent element to function effectively. These selectors will automatically target the appropriate child elements based on their position within the parent, even if the parent is not specified.

To illustrate, consider the following code:

<youdontknowwhat!>
   <p class="select-me">One</p>
   <p class="select-me">Two</p>
</youdontknowwhat!>

To select the second paragraph with.select-me class in this example, simply use the following selector:

.select-me:nth-child(2)

This selector will work regardless of the name or type of the parent element because it specifies the nth child directly.

Explanation:

:first-child and :nth-child selectors utilize the universal child selector '*', which matches any element. Therefore, they can be used to select any child element without specifying a specific parent. The nth-child(n) syntax represents the nth child element within its parent, where 'n' is the specified position.
