Remarks

The sub and super values are supported on text. The auto value is supported on the currentStyle object. The other values are supported on objects that support IHTMLTableCol::vAlign.

The auto value is identical to the baseline value when the IHTMLCurrentStyle2::layoutFlow is horizontal. When the IHTMLCurrentStyle2::layoutFlow is vertical-ideographic, the auto value is identical to the middle value.

As of Internet Explorer for Windows Phone 8.1 Update, Internet Explorer for Windows Phone supports IHTMLCurrentStyle::verticalAlign: middle when IHTMLCurrentStyle::display is set to inline-block on an element.

Examples

This example uses the IHTMLCurrentStyle::verticalAlign property to align text within table cells.

<table>
   <tr>
      <td id="top">top</td>
      <td id="middle">middle</td>
      <td id="bottom">bottom</td>
   </tr>
</table>

In the first table cell, the IHTMLCurrentStyle::verticalAlign property aligns the text to the top, in the second table cell, the IHTMLCurrentStyle::verticalAlign property aligns text to the middle, and in the third table cell, the IHTMLCurrentStyle::verticalAlign property aligns text to the bottom.

td {
   height: 100px;
   width: 100px;
   border: 1px solid #000;
}
#top {
   vertical-align: top;
}
#middle {
   vertical-align: middle;
}
#bottom {
  vertical-align: bottom;
}

You can see the three table cells with different text alignment below.

The following example uses the IHTMLCurrentStyle::verticalAlign property to align text within a paragraph.

<p><span id="baseline">lorem ipsum dolor</span><span id="sub">lorem ipsum dolor</span><span id="super">lorem ipsum dolor</span></p>

Here, each span of text uses the IHTMLCurrentStyle::verticalAlign property to align the text to the baseline, to subscript, and to superscript.

#baseline {
   vertical-align: baseline;
}
#sub {
   vertical-align: sub;
}
#super {
   vertical-align: super;
}

You can see paragraph of text below.
