Solution 1:

Use HTML character references:

<html>

Should output

<html>

Solution 2:

Try doing:

&lt;html&gt;

Solution 3:

Special characters in HTML, such as '<', '>', '"' and '&' can be printed using the following format:

&name;

where name would be replaced by a character name. The most common would then be

&lt;   =   <    (less than)
&gt;   =   >    (greater than)
&amp;  =   &    (ampersand)
&quot; =   "    (double quote)

So to write <html> you would write in HTML:

&lt;html&gt;

Solution 4:

If you want to display <html> literally, use reference to represent the tag open delimiter < and the tag close delimiter >, for example:

&lt;html&gt;

This will then be displayed as:

<html>
