Indispensable for checking browser support before I start coding. Clear tables and up-to-date info save me loads of guesswork.

I check Can I Use every time I use a newer CSS or JavaScript feature. Quick to load and super easy to understand at a glance.

Perfect tool when you need to avoid surprises on old browsers. The compatibility charts are simple but incredibly useful.
