11. Html tags
Html tags are used to mark up html elements
The html tag is a command the web browser interprets(translates)
The html tags are surrounded by less than and greater than characters. These
characters are called as angular brackets(<,>)
The html tags always come in pairs that is a starting tag and closing tags i.e
<html>…..</html>
The text in between the starting tag and ending tag is called as element content.
Example:
<html>
Hello
</html>
All the html tags are predefined tags
The html tags are not case sensitive that is the uppercase letters and lower case
letters are same.
The entire html document must be written in between html starting tag (<html>)
and html closing tag </html>
The <html> tag in a document represents that the document is a html document
