Quick Reference
The toggleClass() method toggles between adding and removing one or more class names from the selected elements.
This method checks each element for the specified class names. The class names are added if missing, and removed if already set. And by using the “switch” parameter, you can specify to only remove, or only add a class name.
$('p').toggleClass()// add or remove the .section class to all paragraph elements
$('p').toggleClass('section');Syntax
$(selector).toggleClass(classname, function(index, currentclass), switch)Note
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. This ensures that all of the page elements that you may be selecting are in place before running the code on them.

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 document <head>
- 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
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.
