Common Confusions - 2 Topics

Why don't I see the tooltip all the time?

The tooltip only appears when you hover the mouse over the element with a title attribute. It is not visible by default.

💡 Hover over the element to see the tooltip.

Why does the tooltip text sometimes get cut off or look different?

The tooltip style and size depend on the browser and operating system. It is not customizable with CSS.

💡 Expect native style tooltips that vary by browser.
