mouse hover in HTML function to pop out or zoom in pic
<p>I am an oracle guy and am struggling to write an HTML function, I would really appreciate your help. 
What i want to achieve is i have a 4 picture or one pictures with 4 parts, and once the mouse over each part it needs to pop out or get zoomed in. 
<a href="https://i.stack.imgur.com/x2b1V.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/x2b1V.png" alt="enter image description here"></a>
ultimately i want once the mouse hover any part to pop out,
FYI i can have the part saved as pictures. so the original picture will be split into 4 parts.
please share the code to do so, or if you have any information please let me know, your help is highly appreciated </p>

<p>thanks in advance</p>
