</script>Frequently Asked Questions
No. The input from a 'prompt()' box is plain text and visible on the screen. Do not use it for sensitive passwords or credit card data.
No. The prompt dialog is a browser-native interface and cannot be styled with CSS. For custom designs, you must build a custom HTML modal using forms.
The function returns 'null'. You should always check for 'null' in your code to handle cases where the user declines to answer.
