Who knows what does the title ATTRIBUTE do in HTML?

Answer 1

U need a quick search in google to understand it
Or this is enough if u have a good background in html
All HTML elements can have attributes

Attributes provide additional information about an element

Attributes are always specified in the start tag

Attributes usually come in name/value pairs like: name="value"

Answer 2

You didn't get me this is an attribute called title

Like :
<p title="this is an explanation" > this is a paragraph </p>
