SVG animation with CSS

If you're looking to add some spice to your web designs, you may be considering adding animation. SVG animation with CSS can be used to create rich, interactive experiences on the web. SVG is a vector graphic format that can be scaled to any size without losing quality.

CSS is a style sheet language that can be used to style HTML elements. Combined, these two technologies can be used to create animations that are responsive, fluid, and resolution-independent.

When it comes to animations, SVG gives you more control and flexibility than other image formats. In this tutorial, we're going to show you how to animate SVG with CSS. We'll provide some examples so you can see how CSS animations can be used to create various effects.

What is an animation?

Animation is the process of creating motion and shape change illusion by means of the rapid display of a sequence of static images that minimally differ from each other. The illusion—as in motion pictures in general—is thought to rely on the phi phenomenon.

Animations can be recorded on either analogue media, such as a flip book, motion picture film, video tape, digital media, including formats such as animated GIF, Flash animation or digital video.

The term "animation" can also refer to the process of creating an animation. The process of creating an animation involves creating the individual frames, stringing the frames together, and then adding any necessary sound or other effects.

Animation is becoming increasingly popular in a variety of industries and for a variety of purposes. It can help engage viewers and communicate messages in a more effective and interesting way than live action video.

It can be used to communicate difficult or sensitive topics in a way that is less likely to offend or be misinterpreted. It is used to create educational content that is more engaging and easier to understand than text-based content and can be used to produce content that is more visually stimulating and thus more likely to hold viewers' attention.

What is an SVG?

SVG (Scalable Vector Graphics), is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. The SVG specification is an open standard developed by the World Wide Web Consortium (W3C) since 1999.

SVG images and their behaviors are defined in XML text files. This means that they can be searched, indexed, scripted, and compressed. As XML files, SVG images can be created and edited with any text editor, but are more often created with drawing software.

Because they are XML files, SVG images can be created and edited with any text editor, but are more often created with drawing software.

    <svg version="1.1" xmlns="">
      <rect width="200" height="100" fill="#2ecc71" />

Browser supports svg images through:

  • HTML <img> or <svg> elements
  • CSS background-image
  • CSS list-style-image
  • CSS content
  • SVG <image> element
  • SVG <feImage> element
  • Canvas drawImage function

SVG animations are highly used to create website icons, logos, infographics and illustrations.

SVG animation techniques

There are two different SVG animation techniques:

Stroke Dasharray

The stroke-dasharray property in CSS sets the length of dashes in the stroke of SVG shapes. More specifically, it sets the length of a pattern of alternating dashes and the gaps between them.


stroke-dasharray: none | <dasharray> | initial | inherit;


path {
  stroke-dasharray: 5; /* dashes and gaps are both 5 units long */

Stroke Dashoffset

The stroke-dashoffset property in CSS defines the location along an SVG path where the dash of a stroke will begin. The higher the number, the further along the path the dashes will begin.


stroke-dashoffset: length | initial | inherit;


path {
	stroke-dashoffset: 100;

SVG animation with CSS

Before getting started with animating SVG with CSS, prepare an SVG file to animate it using CSS. CSS animation consists of two parts: keyframes and animation properties. By defining the keyframes and animation properties we can create a CSS animation.

Define SVG path to animate

The first step is the creation of SVG file which is to be used for animation. Here I have created a rectangle using svg. The rect element draws a rectangle on the screen.

<svg viewBox="0 0 485 97">
    <g stroke="none" stroke-width="1" fill-rule="evenodd">

.path {
    stroke: #000;
    fill: transparent;
    stroke-dasharray: 500;
    stroke-dashoffset: -500;

The class attribute is used to apply unique styling and formatting with CSS.

i.) stroke - It is used to add a border to the SVG rectangle.

ii.) stroke-dasharray - Sets the length of the dashes in the strokes.

iii.) stroke-dashoffset - defines the location along an SVG path where the stroke begins.

iv.) fill - It fills in the color of the rectangle.

Animating with CSS

CSS animations are a great way to add interactivity and life to your web pages. By using a few simple properties, you can create complex animations that will engage your users and add personality to your site.

While creating CSS animation sequence, you have to style the svg element you want to animate using the keyframes, animation properties or sub-properties.

CSS animation is mainly made up of two parts:

  1. By defining animation properties
  2. By defining @keyframes

1. By defining animation properties

With the help of the animation properties you can configure the timing, duration, and other details of how the animation sequence should progress. This is not the actual animation sequence, it can be done only using the @keyframes.

Sub-properties in animation property:

i.) animation-delay

The animation-delay property is used to specify how long an animation should wait before starting. This can be useful for creating animations that need to start at a later point in time, or when you want to stagger the start of multiple animations. The animation-delay property can be specified in either seconds or milliseconds.

/* Single animation */
animation-delay: 3s;
animation-delay: 0s;
animation-delay: -1500ms;

/* Multiple animations */
animation-delay: 2.1s, 480ms;

/* Global values */
animation-delay: inherit;
animation-delay: initial;
animation-delay: revert;
animation-delay: revert-layer;
animation-delay: unset;

ii.) animation-direction

The animation-direction allows an animation to play in alternate cycles. By default, animations run from start to finish that is in forward cycle. The animation-direction property can override this property.

You can also set it to "reverse", which will play the animation backwards. You can also set it to "alternate", which will play the animation forwards first, then backwards, then forwards again, etc. Finally, you can set it to "alternate-reverse", which will play the animation backwards first, then forwards, then backwards again, etc.

/* Single animation */
animation-direction: normal;
animation-direction: reverse;
animation-direction: alternate;
animation-direction: alternate-reverse;

/* Multiple animations */
animation-direction: normal, reverse;
animation-direction: alternate, reverse, normal;

iii.) animation-duration

The animation-duration property defines the length of time that an animation should take to complete one cycle and this is a great way to control the speed of an animation.. The value can be specified in either seconds or milliseconds.

The default value is 0s, meaning that no animation will take place. A higher value will make the animation go faster, and a lower value will make it go slower. By default, animations run at a speed of 60 frames per second.

If you want an animation to last 10 seconds, you can set the animation-duration property to 10s.

/* Single animation */
animation-duration: 6s;
animation-duration: 120ms;

/* Multiple animations */
animation-duration: 1.64s, 15.22s;
animation-duration: 10s, 35s, 230ms;

iv.) animation-fill-mode

The animation-fill-mode specifies how a CSS animation should apply styles to its target before and after it is executed. The four values of animation-fill-mode are: none, forwards, backwards, and both.

With the none value, the target will not receive any styles from the animation. forwards means that after the animation is finished, the target will retain the styles that were applied last by the animation.

backwards means that the target will receive the styles applied by the animation immediately, before the animation has even started.

Both means that the animation will apply the styles both before and after it is executed. The default value for animation-fill-mode is none.

/* Single animation */
animation-fill-mode: none;
animation-fill-mode: forwards;
animation-fill-mode: backwards;
animation-fill-mode: both;

/* Multiple animations */
animation-fill-mode: none, backwards;
animation-fill-mode: both, forwards, none;

v.) animation-iteration-count

It specifies the number of times an animation should be played. It can be a number, or the keyword "infinite".

When animation-iteration-count is a number, the animation will be played that number of times. For example, if it is 5, the animation will be played 5 times.

If animation-iteration-count is the keyword "infinite", the animation will be played forever.

/* Keyword value */
animation-iteration-count: infinite;

/* <number> values */
animation-iteration-count: 3;
animation-iteration-count: 2.4;

/* Multiple values */
animation-iteration-count: 2, 0, infinite;

vi.) animation-name

The animation-name property is one of the most important property. It can be used to specify the name of an animation, which is then used to reference the @keyframes for that animation.

/* Single animation */
animation-name: none;
animation-name: test_05;
animation-name: -specific;
animation-name: sliding-vertically;

/* Multiple animations */
animation-name: test1, animation4;
animation-name: none, -moz-specific, sliding;

vii.) animation-play-state

The animation-play-state is a CSS property that determines whether an animation is running or paused. It can be used to pause and resume an animation.

The property takes two values: running and paused. By default, an animation is running. To pause an animation, set the animation-play-state property to paused.

/* Single animation */
animation-play-state: running;
animation-play-state: paused;

/* Multiple animations */
animation-play-state: paused, running, running;

viii.) animation-timing-function

When it comes to animating elements on a web page, the CSS property animation-timing-function is an another important property to understand. This property determines how an animation will progress over time, and can be used to create a variety of different effects.

The default value is linear, which means the element will change at a constant rate. However, there are a number of other options that can be used to create different types of animations.

/* Keyword values */
animation-timing-function: ease;
animation-timing-function: ease-in;
animation-timing-function: ease-out;
animation-timing-function: ease-in-out;
animation-timing-function: linear;
animation-timing-function: step-start;
animation-timing-function: step-end;

/* Function values */
animation-timing-function: cubic-bezier(0.1, 0.7, 1, 0.1);
animation-timing-function: steps(4, end);

/* Steps Function keywords */
animation-timing-function: steps(4, jump-start);
animation-timing-function: steps(10, jump-end);
animation-timing-function: steps(20, jump-none);
animation-timing-function: steps(5, jump-both);
animation-timing-function: steps(6, start);
animation-timing-function: steps(8, end);

/* Multiple animations */
animation-timing-function: ease, step-start, cubic-bezier(0.1, 0.7, 1, 0.1);

animation Shorthand:

animation: 3s infinite alternate slidein;

2. By defining animation @keyframes

By using @keyframes, you can control the start, end and intermediate steps in a CSS animation. This can be used to create smooth, fluid animations that look great on any device.


@keyframes animationname {keyframes-selector {css-styles;}}


@keyframes slidein {
  100% {
    margin-left: 100%;
    width: 300%;

  0% {
    margin-left: 0%;
    width: 100%;

0% indicates the first moment of the animation sequence, while 100% indicates the final state of the animation. Because these two times are so important, they have special aliases: from and to. Both are optional. If from/0% or to/100% is not specified, the browser starts or finishes the animation using the computed values of all attributes.

In our example, we have used the animation shorthand and set the animation-name as animate, animation-delay to 3 seconds, animation-direction to forwards and animation-iteration-count to infinite.

The @keyframes is set to 100% which indicates that the animation sequence should start and finish at the final state.

CSS code for animation:

body {
  background: #00467F;
  background: -webkit-linear-gradient(to right, #A5CC82, #00467F);
  background: linear-gradient(to right, #FFEFBA, #FFFFFF );

.svgWrapper {
  position: fixed;
  top: 65%;
  left: 70%;
  transform: translate(-50%, -50%);
  svg {
    width: 60rem;

  .path {
    stroke: #000;
    fill: transparent;
    stroke-dasharray: 500;
    stroke-dashoffset: -500;
    animation: animate 5s forwards infinite; /* Animation Shorthand */

/* Animation Sequence */

@keyframes animate {
  100% {
    stroke-dashoffset: 500;

The complete SVG animation with CSS code:


In conclusion, SVG animation with CSS provides possibilities for displaying dynamic, interactive content. With CSS animations, authors can define multiple animations simultaneously and execute them synchronously.

SVG animations use CSS animations as a fallback mechanism, adding the ability to define animations for elements and SVG shapes. SVG animations are best suited for drawing simple shapes or animations based on UI events such as hover, click, or scroll. Complex animations, or animations using non-UI events, are best done with JavaScript.

Finally, SVG animations can be animated with CSS animation properties, such as ease, delay, duration, and timing-function. This opens the door to a plethora of new possibilities for creating animated content.
