CSS Overflow Playground
Preview overflow behavior in a fixed-size content box.
Understand overflow behavior
overflow decides what happens when content is bigger than its box — scroll, clip, or spill out — and the variants (auto, hidden, scroll, clip) behave subtly differently. This playground lets you preview each in a fixed-size box so the effect is clear.
Overflow bugs are a common source of mysterious scrollbars and cut-off content, and seeing the behavior directly is the fastest way to understand it. Experiment with the values against real content and copy the one that does what you intend.
Copy-ready CSS
The CSS is generated live in your browser as you adjust the controls, so there is nothing to install and nothing is uploaded. Copy the ready-to-use declaration straight into your stylesheet, tweak the values to taste, and it will render exactly as it does in the preview here.
