The p tag is for ‘paragraph‘.

HTML provides only one level of paragraph but you can alter the size of the text inside the paragraph.

Inside the <p> tag you can give many number of attributes.

For example, 

<p>This is my first website</p>

<p>ProgrammingTute</p>

Output: 

This is my first website

ProgrammingTute

Look at the results of this. The two lines will now appear on two lines.

Instead of this you can use <br> tag. The HTML content should be seen just like a book with paragraphs where appropriate.

HTML has six levels of headings, which use the elements <h1>, <h2>, <h3>, <h4>, <h5>, and <h6>. You use different sizes for your headings. While displaying any heading, browser adds one line before and after that heading.

For example:

<h1>ProgrammingTute 1</h1>
<h2>ProgrammingTute 2</h2>
<h3>ProgrammingTute 3</h3>
<h4>ProgrammingTute 4</h4>
<h5>ProgrammingTute 5</h5>
<h6>ProgrammingTute 6</h6>

Output:

PROGRAMMINGTUTE 1

PROGRAMMINGTUTE 2

PROGRAMMINGTUTE 3

PROGRAMMINGTUTE 4

PROGRAMMINGTUTE 5

PROGRAMMINGTUTE 6

 
Important note is that <h1>tag should be used only once in a document, however it is supposed to be the main heading of the page and shouldn’t be used multiple times.

But the tags <h2> to </h6> can be used often.

But remember they should always be used in order, as prescribed.
