Why Do Inline-Block Images Have Extra Space Below Them, and How Can I Fix It?

Mysterious Space beneath Images: Unveiling the Cause and Solution

When displaying images as inline-block elements, you may encounter a perplexing scenario where a vacant space appears underneath them, despite setting padding and margin to zero. This puzzling phenomenon stems from the inherent behavior of inline-block elements, which resemble characters in text.

Just as letters have baselines denoting the bottom line of characters, images align with this baseline. Consequently, even in the absence of flanking text, the image aligns to the baseline, causing a gap below due to the reserved space for hanging tails on letters like 'p' and 'q'.

To remedy this, we can harness the power of vertical-align:bottom. This CSS property anchors the image to the bottom of the line, effectively removing the lingering whitespace.

For images smaller than the line height, a subtle tweak is necessary. Introducing line-height:1px to the container element banishes any potential space intrusion above the image.

Adopting these simple adjustments ensures that images nestle snugly within their allotted space, without the enigmatic presence of empty areas beneath them.
