Why Doesn't My SVG Animation Work in Internet Explorer 11?

IE11 SVG Animation Issue Resolved: Understanding Browser Support

In the given code sample, the SVG element representing a circle fails to display in Internet Explorer 11, despite the animation appearing to function correctly. To understand this behavior, we need to examine the browser support for SVG animations.

SVG CSS Animations in Internet Explorer

Internet Explorer 11, unlike modern browsers, does not fully support CSS transitions and animations for SVG elements, specifically for the stroke-dasharray property. This is because IE11 lacks the necessary rendering engine to handle SVG transformations smoothly.

Microsoft Developer Documentation

As documented by Microsoft, SVG CSS Transitions and Animation are only supported in Microsoft Edge browser builds 10240 . This means that IE11 and older versions of Edge will not render SVG animations as expected.

Alternative Animation Approaches

To resolve the issue and display the SVG circle correctly, there are several options:

• Ensure the stroke Attribute is Present: In the original code, the SVG circle element does not have a stroke attribute. Adding it to the code will make the circle visible.
• Use a JavaScript Animation Library: Libraries like GreenSock Animation Platform (GSAP) offer cross-browser support for SVG animation, including stroke-dasharray transformation. Using the DrawSVGPlugin within GSAP provides a reliable alternative to CSS animations for SVG elements.

Conclusion

SVG animation is not fully supported in IE11 due to its limited rendering capabilities. By ensuring that the SVG element has the necessary attributes and considering alternative animation approaches such as JavaScript libraries, developers can achieve cross-browser compatibility for SVG animations.
