Overflow Clip and Scroll

A log panel gains a fixed height, clips extra rows, then styles its border, padding, and individual entries for a readable bounded region.

Program

Content sometimes exceeds the box that contains it. Overflow rules decide whether that extra content is visible, clipped, or scrollable.

  1. Limit the panel height.

    The log has a maximum height.
    A height limit makes overflow behavior visible.

  2. Clip content beyond the edge.

    Rows beyond the box edge are hidden.
    Hidden overflow clips extra content without showing scrollbars.

  3. Frame the clipped region.

    The log reads as a bounded panel.
    Padding and border make the clipping edge clear.

  4. Style each log row.

    Each visible log entry becomes a compact row.
    Child spacing still participates inside the clipped area.
overflow Overflow is content that extends beyond an element box.
clipping Clipping hides content outside the visible region of a box.
