HTML document structure
HTML document rules
HTML elements can be nested
HTML tags can be nested. One HTML Element can have other HTML elements inside it. e.g –
<body> <h1><b>This is a Heading</b></h1> <b>Text is bold</b> </body>
in the above HTML markup, We have nested the HTML elements.
HTML documents are case-insensitive
We can write HTML code in either cases i.e in Uppercase or in lowercase.
<h1><b>This is a Heading</b></h1>
<H1><b>This is a Heading</B></h1>
both of the above lines will print same result.
