Character Entities (Escape Characters)

 ​Character entities are used when you need to display reserve characters that browsers would otherwise interpret as HTML code, or characters not readily available on a standard keyboard.

Character	Description	Numeric Entity	Named Entity	Common Use Case
"	Quotation mark	"	"	Used inside attribute values or text
&	Ampersand	&	&	Used to display bare ampersands in text
<	Less-than (left angle bracket)	&#060;	&lt;	Prevents browser from mistaking as tag start
>	Greater-than (right angle bracket)	&#062;	&gt;	Prevents browser from mistaking as tag end
	Non-breaking space	&#160;	&nbsp;	Forces a space without line wrapping
©	Copyright symbol	&#169;	&copy;	Footer copyright notices

​Comment 

Syntax: Opens with <!-- and closes with -->.

​It's ignored by the browser and will not appear on the page.

​Comments are still visible to anyone viewing the web page's raw source code. 

Never place sensitive information (passwords, private keys, API credentials) inside HTML comments.

​Primary Uses:

​Documentation: Labeling major section starts/ends (e.g., <!-- Start Header -->).

​Developer Notes: Recording who modified code, dates, or layout reasons.

​Debugging: Temporarily disabling lines of code without deleting them.
