# Defining Animations for SVG Components

You can use child components in the **\<svg>** component to animate attributes over time.

## Attribute Style Animation

In the [animate](../reference/apis-arkui/arkui-js/js-components-svg-animate.md) child component of the **\<svg>** component, set **attributeName** to the attribute you want to animate, **from** to the animation start value, and **to** to the animation end value.


```html
<!-- xxx.hml -->
<div class="container">
  <svg>
    <text x="300" y="300" fill="blue">
      Hello
      <animate attributeName="font-size" from="30" to="60" dur="3s" repeatCount="indefinite">
      </animate>
      <animate attributeName="fill" from="red" to="blue" dur="3s" repeatCount="indefinite">
      </animate>
      <animate attributeName="opacity" from="1" to="0.3" dur="3s" repeatCount="indefinite">
      </animate>
    </text>
    <text x="300" y="600" fill="blue">
      World
      <animate attributeName="font-size" from="30" to="60" values="30;80" dur="3s" repeatCount="indefinite">
      </animate>
      <animate attributeName="fill" from="red" to="blue"  dur="3s" repeatCount="indefinite">
      </animate>
      <animate attributeName="opacity" from="0.3" to="1" dur="3s" repeatCount="indefinite">
      </animate>
    </text>
  </svg>
</div>
```

> When values is also set, the from and to settings do not take effect.

## Motion Path Animation

In the [animateMotion](../reference/apis-arkui/arkui-js/js-components-svg-animatemotion.md) child component of the &lt;svg&gt; component, set path to define a shape for the animation.


```html
<!-- xxx.hml -->
<div class="container">
  <svg fill="white" width="800" height="900">
    <path d="M300,200 h-150 a150 150 0 1 0 150 -150 z" fill="white" stroke="blue" stroke-width="5" >
    </path>
    <path fill="red" d="M-5,-5 L10,0 L-5,5 L0,0 Z"  >
      <animateMotion dur="2000" repeatCount="indefinite" rotate="auto-reverse"path="M300,200 h-150 a150 150 0 1 0 150 -150 z">
      </animateMotion>
    </path>
  </svg>
</div>
```

## animateTransform Animation

In the [animateTransform](../reference/apis-arkui/arkui-js/js-components-svg-animatetransform.md) child component of the **\<svg>** component, set attributeName to bind the corresponding attribute to the **transform** attribute, and set **type** to the animation type, **from** to the start value, and **to** to the end value.


```html
<!-- xxx.hml -->
<div class="container" style="">
  <svg>
    <line x1="90" y1="300" x2="90" y2="730" stroke-width="10" stroke="black" stroke-linecap="round">
      <animateTransform attributeName="transform" attributeType="XML" type="translate"  dur="3s" values="0;30;10;30;20;30;25;30" keyTimes="0;0.3;0.5;0.7;0.8;0.9;1.0;1.1" 
      fill="freeze">
      </animateTransform>
    </line>
    <circle cx="500" cy="500" r="50" stroke-width="15" fill="red" stroke="#e70d0d">
      <animateTransform attributeName="transform" attributeType="XML" type="rotate"  dur="3s" values="0;30;10;30;20;30;25;30" keyTimes="0;0.3;0.5;0.7;0.8;0.9;1.0;1.1" fill="freeze">
      </animateTransform>
      <animateTransform attributeName="transform" attributeType="XML" type="scale"  dur="6s" values="1;1;1.3" keyTimes="0;0.5;1" fill="freeze"></animateTransform>
      <animateTransform attributeName="transform" attributeType="XML" type="translate"  dur="9s" values="0;0;300 7" keyTimes="0;0.6;0.9" fill="freeze"></animateTransform>
    </circle>
    <rect width="500" height="200" x="90" y="840">
      <animateTransform attributeName="transform" attributeType="XML" type="skewY"  dur="6s" values="0;0;30" keyTimes="0;0.5;1" fill="freeze"></animateTransform>
    </rect>
    <line x1="650" y1="300" x2="650" y2="600" stroke-width="20" stroke="blue" stroke-linecap="round">
      <animateTransform attributeName="transform" attributeType="XML" type="translate"  dur="9s" values="0;0;0 800" keyTimes="0;0.6;1" fill="freeze"></animateTransform>
    </line>
  </svg>
</div>
