jQuery methods

After selecting the DOM element that you want to manipulate, the jQuery library has a ton of methods that you can use to work on them. The .css() method takes two parameters, the first one is the css property that you want to change, and the second is the change that you want to make. You can also add and remove classes using the .addClass() or .removeClass() methods. The .keypress() and .on() methods work as event handlers, and can trigger functions when certain events take place on the specified selectors. The .fadeOut() method will hide the matched elements by fading them to transparent, and the .slideUp() method will hide the matched elements with a siding motion. It can also make writing AJAX calls way easier than originally writing it with vanilla javascript.
