Why is There Extra White Space Below My Images, and How Can I Fix It?

Fixing the Mysterious White Space Below Image Tags

When replacing background images with img tags, users might encounter a puzzling white space below the image. This space emerges due to the baseline alignment of inline-level elements like images. Certain letters descend below the baseline, causing a subtle elevation from the container's bottom edge.

To resolve this issue, you can employ various techniques:

1. Adjust Vertical Alignment: Apply vertical-align: bottom to your img tag to align the image's bottom edge to the container's bottom edge. If necessary, experiment with middle, top, or text-bottom to find the best alignment.
2. Switch to Block Display: Replace the inline display by setting display: block on your img tag. This will treat the image as a block-level element, eliminating the need for baseline alignment.
3. Modify Line Height: Adjust the line-height property on the parent container to reduce the space below the image. For instance, setting line-height: 0 can resolve the problem.
4. Set Font Size to Zero: Set font-size: 0 on the parent container to eliminate the vertical gap. If necessary, restore the font size on the child element directly.

By implementing these techniques, you can fix the white space issue beneath image tags, ensuring a clean and aesthetically pleasing website design.
