In the previous article "How to add click and double-click events to an element through jQuery", I will introduce you to the method of adding click and double-click events to an element using jQuery. Friends who need it can learn. Learn about it~

The main content of this article is to introduce how to use jQuery to animate paragraph elements.

So in this article, we will use jQuery to animate paragraph elements by clicking a button, and mainly use the animate() method to achieve animation effects. The animate() method is used to change the state of an element with CSS styles. This method can also be used to change CSS properties to animate selected elements.

Let’s go directly to the code:

<!DOCTYPE HTML>
<html>
<head>
    <meta charset="UTF-8">
    <title></title>
    <script src="jquery.min.js"></script>
    <script>
        $(document).ready(function () {
            $("button").click(function () {
                $("#GFG").animate({
                    opacity: 0.5,
                    fontSize: "3em",
                }, 1000);
            });
        });
    </script>
</head>

<body style="text-align: center;">
<h1 style="color: #ff311f;">

What everyone needs to master here isanimate()Method:

The animate() method performs a custom animation of a CSS property set. This method changes an element from one state to another using CSS styles. CSS property values change gradually, allowing you to create animated effects. Only numeric values can be animated (e.g. "margin:30px"). String values cannot be animated (such as "background-color:red").

→Note: Please use " =" or "-=" to create relative animation. The syntax of

animate() is as follows:

(selector).animate({styles},speed,easing,callback)

Parameter styles is required: specifies one or more CSS properties/values that produce animation effects.

Note: When used with the animate() method, the property name must be camelCase: you must use paddingLeft instead of padding-left, marginRight instead of margin-right, and so on.

The parameter speed is optional: specifies the speed of the animation.

Possible values:

Milliseconds
"slow"
## "fast"

The easing parameter is optional: specifies the speed of the element at different points in the animation. The default value is "swing".

Possible values:

"swing" - moves slower at the beginning/end, faster in the middle
" linear" - moving at a constant speed

# Tip: More available easing functions are provided in the extension plug-in.

The callback parameter is optional: the function to be executed after the animate function is executed.
