Description Jeremy T. Gibson 2007-09-11 07:06:01 UTC
In a document using the HTML 4.01 DTD (and probably others), Validator is incorrectly reporting that the allowable values for the "align" attribute of a "td" tag are: "top", "middle", "bottom", "left", "right".  However, this is incorrect according to the specification (; specifically, the attribute also supports the "center" and "char" parameters and does not support the "top", "middle", or "bottom" parameters (which belong to the "valign" attribute, along with "baseline").

(One could use the text-align attribute of CSS as a work-around, but this is still a bug in the parser because it is not conforming to the specification.)

Here is an example table which fails for me:

<table border="1" width="90%" class="indent">
<tr valign="top">
  <th>Stable Suspension Layouts</th></tr>
<tr valign="top">
  <td>The following configurations are all the possibilities which satisfy the rules of longitudinal and lateral stability and which provide stability on the four different hemispheres (fore, aft, port, star).</td></tr>

("indent" is a simple CSS element containing a "margin-left: 1cm" attribute.)

Er, oops.  The second td tag is supposed to be <td align="center"> but I included the wrong snippet. =P

> Er, oops

You're having me puzzled here. 

The spec says:
align = left|center|right|justify|char
and if I test a document with 
<td align="blah">
The error is:
Error  Line 16, Column 17: value of attribute "ALIGN" cannot be "BLAH"; must be one of "LEFT", "CENTER", "RIGHT", "JUSTIFY", "CHAR" .

Not a bug?

Oh, you have gotta be kidding me.  Apparently I was sticking the "center" inside the img tag inside the cell, and I assumed that after stripping out the image tag it would still fail (that's why you don't see td align="center").

Not a bug.

Feck. =P
