CSS – offset Property

”;

The CSS shorthand property offset makes it easier for an element to animate along a certain path.

It has many characteristics that together comprise an offset transform.

With this transform, a specified point inside the element (offset-anchor) is aligned to a certain path position (offset-position) at various points along the route (offset-distance).

It also allows the element to be optionally rotated (offset-rotate) to follow the path”s direction.

Constituent Properties

The offset property is a shorthand for the following CSS properties:

offset-anchor

offset-distance

offset-path

offset-position

offset-rotate

Possible Values

The following list of values is accepted by offset shorthand property.

offset-anchor – Defines a point within the element that aligns with an offset position on the path.

offset-path – Defines the path along which the element is animated.

offset-distance – Defines how far along the path the element is placed.

offset-rotate – Optionally rotates the element to align with the direction of the path.

auto – All properties are reset to their default values.

Applies to

Transformable elements

Syntax


offset = [ <''offset-position''>? [ <''offset-path''> [ <''offset-distance''> || <''offset-rotate''> ]? ]? ]! [ / <''offset-anchor''> ]?

CSS offset – path value

The following example demonstrates the usage of offset shorthand property with path value.

       
<html>
<head>
<style>
    @keyframes slide {
        0% {
            offset-distance: 0%;
        }
        100% {
            offset-distance: 100%;
        }
    }
    .container {
        width: 400px;
        height: 200px;
        border: 2px solid #3498db;
        border-radius: 10px;
        position: relative;
        overflow: hidden;
        background-color: #f0f0f0;
        box-shadow: 0 10px 20px rgba(0, 0, 0, 0.5);
    }
    .text {
        position: absolute;

        offset: path(''M 10 100 Q 50 50 90 100 T 170 100 T 250 100'');
        text-shadow: 1px 1px 2px rgba(0, 0, 0, 0.4);

<div class="container">
    <div class="text">This is Sliding Text</div>

CSS offset – path and auto value

The following example demonstrates the usage of offset shorthand property with path and auto value.

<head>
<style>
    @keyframes orbit {
        0% {
            offset-distance: 0%;
            offset-rotate: 0deg;
        }
        100% {
            offset-distance: 100%;
            offset-rotate: 360deg;
        }

        offset: path(''M 200 200 m -100, 0 a 100,100 0 1,0 200,0 a 100,100 0 1,0 -200,0'') auto;
    }
    #sun {
        width: 100px;
