FAQ
What is the difference between overflow-x and overflow-y?
overflow-x controls horizontal overflow while overflow-y controls vertical overflow. Each can be set independently to visible, hidden, scroll, auto or clip. When one axis is set to visible and the other is not, the visible value is automatically computed as auto by the browser.
When should I use overflow: scroll instead of overflow: auto?
Use overflow: scroll to always show the scrollbar, even when there is nothing to scroll. Use overflow: auto to only show the scrollbar when the content actually overflows the container. For a cleaner look, overflow: auto is usually the better choice.
Is CSS Overflow Generator free to use?
Yes, the CSS Overflow Generator is completely free with no signup required. All processing happens locally in your browser, so your code is never uploaded to any server.
