Quick Reference
The :nth-of-type() selector selects all elements that are the nth child of a specified type of their parent.
What this means is that the counting of the child elements DOES take into account the type of element. If the first child was an h1, the second an h2, and then the p. The paragraph is the third child, BUT it’s also the first of type (the first p tag). A second p tag after that, would be the :nth-of-type(2). In other words, we’re only counting the types specified.
So in the example below, we are looking for each second paragraph of the parent and selecting it.
// selects every HTML paragraph that is also the second paragraph of its parent
$('p:nth-of-type(2)')
$('#intro, #footer, .my_paragraphs, h3')
// all .child elements that live within a .father element
$('.father .child')
// all h1 tags that live within a .father element
$('.father h1')
Notice that there is no comma between the classes (but there is a space), which says you are targeting the class .child and it must have an ancestor with the class .father, as shown in the first example. You can include as many ancestors as necessary to be as specific as necessary.
// all p tags that live within a .child element that lives within a .father element
$('.father .child p')
Parameters
The following parameters apply.
| Parameter | Description |
|---|---|
| n | The index of each child to match; must be a number and first element will have the index number 1 not zero) |
| even | Selects each even child element |
| odd | Selects each odd child element |
| formula | Specifies which child element(s) to be selected with a formula (an + b – example: p:nth-child(3n+2) selects each 3rd paragraph, starting at the 2nd child element) |
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.

jQUERY NOTES:
- To use jQuery on your site, it must first be downloaded from the official jQuery site and linked to in your document
head, or linked to via a CDN in your documenthead - It is generally good practice to place your jQuery code/function inside the document load function so that the action takes place ONLY after the document has finished loading
- When using jQuery, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
