W3.CSS supports a different kind of tooltip using w3-tooltip class. Take a look at the following example. Here we've put a tooltiptext within a div and an image and applied w3- tooltip on the parent div.
<div class = "w3-tooltip"> <div class = "w3-text w3-container w3-teal" style = "width:255px;"> <p>Learn HTML5 in simply easy way @Howcodex.com</p> </div> <div> <img src = "html5-mini-logo.jpg" alt = "html5"> </div> </div>
<html> <head> <title>The W3.CSS Tooltips</title> <meta name = "viewport" content = "width = device-width, initial-scale = 1"> <link rel = "stylesheet" href = "https://www.w3schools.com/lib/w3.css"> </head> <body class = "w3-container"> <h2>Hover Demo</h2> <div class = "w3-tooltip"> <div class = "w3-text w3-container w3-teal" style = "width:255px;"> <p>Learn HTML5 in simply easy way @Howcodex.com</p> </div> <div> <img src = "html5-mini-logo.jpg" alt = "html5"> </div> </div> </body> </html>
