valign vs text-align in HTML

Question

I can't figure out the difference between valign vs text-align in HTML in context with the following code:

    <table width="500" border="0">
  <tr>
        <td colspan="2" style="background-color:#FFA500;">
   <h1>Main Title of Web Page</h1>
   </td>
      </tr>

  <tr valign="top">
      <td style="background-color:#FFD700;width:100px;text-align:top;">
      <b>Menu</b><br />
    HTML<br />
      CSS<br />
  JavaScript
     </td>
   <td style="background-color:#EEEEEE;height:200px;width:400px;text-align:top;">
      Content goes here</td>
    </tr>

   <tr>
     <td colspan="2" style="background-color:#FFA500;text-align:center;">

   </tr>
   </table>

The proper values for text-align are left|right|center|justify as it is horizontal, while the valign is vertical so it's top|middle|bottom|baseline. You can also use inherit on both.

Plus, text-align is css while valign is an html attribute. I think align is the html equivalent to text-align, while vertical-align is equivalent to valign.

If you switch text-align to "bottom", you'll notice it doesn't move as bottom isn't valid for text-align. The default (i think) is top. If you put "vertical-align:bottom" though, it will go to the bottom.
