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
