Grid FR to Percentage
Convert CSS Grid 'fr' units to percentage equivalents for fallback support in legacy browsers.
The 'fr' unit is the gold standard for CSS Grid, but legacy environments sometimes require percentage fallbacks for consistent rendering. This tool calculates the percentage equivalent of a fractional unit within a standard 12-column grid system, facilitating backward compatibility without sacrificing modern layout logic.
Using percentages as a fallback ensures that your layout doesn't collapse in browsers that lack full Grid support. This calculation is a vital part of a 'progressive enhancement' strategy, allowing for modern development while maintaining a functional baseline for all users.
Privacy: Layout values are calculated locally. No grid configurations are sent to our servers.
Terms: Calculations assume a total grid weight of 12. Adjust your math if using non-standard grid systems.
