Questions
Does the stopwatch keep running if I close the tab?
Yes. The start time is saved in your browser, so if you close the tab or refresh, the stopwatch picks up where it should be when you come back, laps included.
What is the difference between a lap and a split?
The lap time is how long that one lap took. The split (total) is the elapsed time since you started when you pressed Lap.
How accurate is it?
It measures against your device clock, so it does not drift. Your own reaction time pressing the button (around 0.2 seconds) is the bigger factor.
