Quick Reference
The animate() method performs a custom animation on an HTML element, changing one CSS property value to another gradually, creating an animated effect.
- Only numeric values can be animated (“margin: 10px”)
- String values cannot be animated (“background-color: red”)
- “+=” or “-=” can be used for relative animations
$('div').animate();Syntax
(selector).animate({styles}, speed, easing, callback)$('button').click(function() {
$('div').animate({opacity: '0.2'}, 'slow', 'swing');
});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.

| styles | Specifies one or more CSS properties/values to animate; the property names must be camel-cased when used with the animate() method (paddingLeft instead of padding-left, marginRight instead of margin-right, etc.) (required) Only numeric values can be animated (like "margin: 20px"); string values cannot be animated (like "background-color: red").

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.
