Values

  • auto
    • : The default scroll overflow behavior occurs as normal.
  • contain
    • : Default scroll overflow behavior (e.g., “bounce” effects) is observed inside the element where this value is set. However, no scroll chaining occurs on neighboring scrolling areas; the underlying elements will not scroll. The contain value disables native browser navigation, including the vertical pull-to-refresh gesture and horizontal swipe navigation.
