Thanks Gwynn- but I am looking for something a little more like Stormy's answer. &nbsp;I realize HTML is not case sensitive. &nbsp;But thanks for the input.

Recommended is not to use uppercase characters as Stormy already said, that said...if you do use uppercase, use them concequently to use proper XML syntax.<br />

Thanks everyone. &nbsp;That is what I was hoping for since I have been using lower case for years!

Can anyone give me a definitive answer: should HTML tags be uppercase or lowercase? &nbsp;Just wondering really. &nbsp;It seems the W3C site uses lower case for both tags and attributes so I am guessing that is how it should be... <br />
<br />
In other words should I write:<br />
<br />
&lt;TABLE cellpadding=&quot;0&quot; cellspacing=&quot;0&quot; border=&quot;0&quot;&gt;<br />
or<br />
&lt;table cellpadding=&quot;0&quot; cellspacing=&quot;0&quot; border=&quot;0&quot;&gt;<br />
<br />
If someone could could point me to the actual guideline I would appreciate it.<br />
<br />
Thanks!

Capitalize HTML tags?

HTML (HyperText Markup Language) is the main markup language for creating web pages and other information to be displayed in a web browser, providing both the structure and content for what is sent from a web server through the use of tags. The current implementation of the HTML specification is HTML5.
