If hovering over a browser tab, the text that appears is generated from the <title>
tag within the <head>
section of the html page it belongs to, the below is the example from this page:
<title>hover - Javascript onmouseover event - Stack Overflow</title>
The text that appears when hovering over an on page element is generated from the title attribute such as <img src="cat.png" title="A photo of a cat">
, its primary use being to provide advisory information for the element it belongs to. If an element has no title attribute, it will inherit its title from its parent.
