I checked the code you shared — it works fine on my Chrome. But your issue might be due to one of these:

Your Chrome version might be older — try updating it.

Could be related to zoom level or screen scaling (like 125%). Try setting zoom to 100%.

Try running it in incognito mode — maybe an extension is affecting it.

Or it might just be a small browser glitch — try clearing cache or refreshing with Ctrl + Shift + R.
