Solving Vertical Alignment Issues in HTML Images
Based on the provided code snippet, I will attempt to identify the issue with vertical alignment.
The problem seems to be with the vertical-align property, which is missing in most of the image elements. To fix this, you can add the vertical-align: middle; style attribute to each img element that requires vertical centering.
Here’s an updated version of the code snippet:
<td width="5" height="35" align="middle"> <table> <tr> <td height="6" colspan="3" valign="bottom"> <img src="em-cr-tp.
