You should not be using the following tags anymore.
An other two HTML tags I came across. Upgrade yourself 😉
align
<div align="center"> </div>
Code language: HTML, XML (xml)
You could use instead:
<div style="margin:0 auto;"></div>
Code language: HTML, XML (xml)
width
<table width="100%">
<tr>
<td></td>
</tr>
</table>
Code language: HTML, XML (xml)
Use the same but inside the style:
<table style="width:100%">
<tr>
<td></td>
</tr>
</table>
Code language: HTML, XML (xml)
