Anime.js is a small, lightweight JavaScript library with a simple and small powerful API. It works with DOM element, CSS and JavaScript object. Animation with CSS properties we can animate any CSS property. Below few of the examples are described with different CSS properties:
Example 1: First we have to set a target the div or element can be class or id, which we want to animate. The CSS background-color is one of the CSS property we are changing here from blue to #F75. The CSS border radius is another CSS property we are changing here. The we will use easing, easeInOutQuad mean just fading and showing, after that we will use the loop – true to keep repeating the animation. You can animate any css property here we showed backgroundColor and borderRadius.
html
<!DOCTYPE html> <html> <head> <title>animejs</title> <script src= </script> </head> <body> <center> <h1 style="color: green;">neveropen</h1> <b> Animation on background color and border radius. </b> <br><br> <div style="background: blue; height: 80px; width: 80px;"> </div> </center> <script> let animation = anime({ targets: "div", backgroundColor: "#F75", borderRadius: "50px", easing: "easeInOutQuad", loop: true, }); </script> </body> </html> |
Output:
Example 2: In this example, we will animate with CSS transform. First, we have to set a target the div or element can be class or id, which we want to animate. The CSS translateX() function will set at 450 to move 450 into positive x-axis). We will use the CSS rotate() function to rotate – 720 degree. The CSS background-color is CSS property but not the part of CSS translate but we can use to change colour. The CSS direction property is set to alternate (move it back and fourth). Then the CSS duration is set for 2000 time for animation in ms) . after that we will use the loop – true to keep repeating the animation.

<!DOCTYPE html> <html> <head> <title>animejs</title> <script src= </script> </head> <body> <center> <h1 style="color: green;">neveropen</h1> <b> Animation on background color and border radius. </b> <br><br> </center> <div style="background: blue; height: 80px; width: 80px;"> </div> <script> let animation = anime({ targets: "div", // Move 250 into positive x-axis translateX: 450, // Degree you want to rotate rotate: "720", backgroundColor: "#f75", direction: "alternate", duration: "2000", loop: true, }); </script> </body> </html> |
Output:
Example 3: Any Object property containing a numerical value can be animated. Here we just changed the value of object property and updated the dom and easing: linear is used to animate it linearly and you can change the round value to see what it is used for.
html
<!DOCTYPE html> <html> <head> <title>animejs</title> <script src= </script> </head> <body> <div></div> <script> var div = document.querySelector("div"); var object = { prop1: 10, prop2: "0%", }; let animation = anime({ targets: object, prop1: 70, prop2: "96%", easing: "linear", round: 1, update: function () { div.innerHTML = JSON.stringify(object); }, }); </script> </body> </html> |
Output:
Example 4: Here, values will contain from value – to value( Dom Attribute ). Such as value inside the input field (numeric)
html
<!DOCTYPE html> <html> <head> <title>animejs</title> <script src= </script> </head> <body> <input style="text-align: center;" type="text" /> <script> let animation = anime({ targets: "input", value: [0, 100], round: 1, easing: "easeInOutExpo", }); </script> </body> </html> |
Output:
Example 5: In this example we will animate SVG attribute. We created a circle of radius 50 centre at position 150, 150, then we applied anime on circle moved the centre to 200, 200 and made radius 60.
html
<!DOCTYPE html> <html> <head> <title>animejs</title> <script src= </script> </head> <body> <center> <h1 style="color: green;">neveropen</h1> <b> SVG Attribute </b> <br><br> <svg height="400" width="400"> <circle cx="50" cy="50" r="40" stroke="black" stroke-width="2" fill="green"/> </svg> </center> <script> let animation = anime({ targets: ["circle"], cx: "300", cy: "300", r: "60", baseFrequency: 0, scale: 1, loop: true, direction: "alternate", easing: "easeInOutExpo", }); </script> </body> </html> |
