CSS Display:inline-block and Positioning:absolute
When using CSS, it's essential to understand the impact of different display and positioning properties on the layout of elements. This question examines how the combination of display:inline-block and position:absolute affects the behavior of elements in a webpage.
Understanding the Problem
The provided HTML code creates five sections, each containing two spans. One span is styled with display:inline-block and the other has position:absolute. However, the absolute positioning causes the containing box to lose track of its required height, resulting in a zero-height box.
Resolving the Height Issue
Since position:absolute removes the element from the normal page flow, it no longer contributes to the height of its container. To resolve this, the height of the container box must be explicitly set.
