Add </ to text without HTML thinking it's a tag

Use < instead of < on html.

<p>&lt;/Hello</p>

You need to use an HTML Escape for both:

• the less than character (<) which is... <
• the greater than character {>) which is... >

This will give you:

</Hello>

which will render in the browser as:

</Hello>

Other useful HTML Escapes include:

• & => &
• " => "
• ' => '
• < => <
• > => >
• [SPACE] =>  
• [NEWLINE] =>
