HTML and CSS Reference
In-Depth Information
charoff
This attribute contains an offset, specified as a positive or negative integer, for
aligning characters as related to the
char
value. A value of
2
, for example, would align
characters in a cell two characters to the right of the character defined by the
char
attribute.
valign
This attribute is used to set the vertical alignment for the table cells with a
<tr>
tag.
The specification defines
baseline
,
bottom
,
middle
, and
top
. Internet Explorer also
allows
center
, which should be the same as
middle
.
Example
<table width="300" border="1">
<tr align="center" valign="middle">
<td>
3
</td>
<td>
5.6
</td>
<td>
7.9
</td>
</tr>
</table>

Notes
• This tag is contained only in the
<table>
,
<thead>
,
<tbody>
, and
<tfoot>
tags. It
contains the
<th>
and
<td>
tags.
• The HTML 3.2 specification defines only the
align
and
valign
attributes for this
element.
• Internet Explorer 6 introduced
ch
and
choff
attributes per a draft standard at the
time, but they do not do anything and later are set as
char
and
charoff
.
• CSS visual changes to tables are suggested, but many sites claim that under strict
variants the various attributes like
bgcolor
no longer work. Testing in modern
browsers (IE 8, Firefox 3) at the time this edition was written does not support these
claims.
• Under the XHTML 1.0 specification, the closing
</tr>
tag is required, but under
older HTML and HTML5, the closing tag is optional.
• There are extended DOM methods for table-related tags like
<tr>
, including
insertRow()
and
deleteRow()
.
<tt> (Teletype Text)
This inline element is used to indicate that text should be rendered in a monospaced font
similar to teletype text. The element is being marked as obsolete or deprecated and should
be avoided in favor of CSS.
Standard Syntax
<tt
class="class name(s)"
dir="ltr | rtl"
