What are some effective polyfills for adding CSS Grid support in older browsers like IE11?

Asked on Jan 14, 2026

Answer

CSS Grid is a powerful layout system, but older browsers like IE11 do not fully support it. Polyfills can help bridge this gap by providing similar functionality. Here’s a conceptual overview of how polyfills work for CSS Grid.

Example Concept: Polyfills for CSS Grid, such as "css-grid-polyfill" or "Grid.js", work by translating grid layout properties into equivalent styles that older browsers can understand. They often use JavaScript to dynamically adjust the layout by converting grid definitions into flexbox or other supported layout techniques. This allows developers to write modern CSS while maintaining compatibility with older browsers.

Additional Comment:

Polyfills are typically JavaScript libraries that mimic CSS Grid behavior.
They can be included in your project to ensure layouts render correctly on unsupported browsers.
Using a build tool like Babel can also help by transforming newer CSS syntax into older equivalents.
Always test your layout in the target browsers to ensure the polyfill works as expected.
