Why Does My Inline Image Have Extra White Space Below It?

Unveiling the Mystery of White Space Beneath Image Tag

Upon replacing a background image with an inline tag, a baffling white space emerged underneath the image, creating a puzzling visual discrepancy.

The Enigma of Descenders

Like text, inline elements such as images are aligned to the baseline, ensuring that characters like "j", "g", and "p" (descenders) have sufficient space to extend below the baseline. This default behavior causes a gap beneath images, even in the absence of margins or padding.

Resolving the White Space

To combat this issue, consider the following solutions:

1. Vertical Alignment Adjustment: Assign vertical-align: bottom to the image tag, aligning it to the bottom of the container. Other options include middle, top, or text-bottom.
2. Inline-to-Block Conversion: Change the image's display style from inline to block, removing the baseline alignment and eliminating the white space.
3. Container Line-Height Management: Adjust the container's line-height property to accommodate the image's height. Setting it to zero, as exemplified in the original code (now subject to linkrot), can effectively address the issue.
4. Container Font Size Manipulation: Assign a font-size of zero to the container. If desired, restore the font size specifically to the child element to maintain readability.

By implementing one of these solutions, you can successfully banish the enigmatic white space and achieve a seamless image layout.
