How to find a right place on a webpage to make a click?

The trouble is huge but a task is very simple.

I have a background image with the small flower on it. I need some action to be done when user press on it. However flower is placed on totally different areas of a screen depending of screen's resolution.

How could I connect "small flower" with a hover zone for a:href?

  <style>
   body {
    background-image: url(images/bg.jpg); 
   }
  </style>

    <body>
      <div>
        <h1><a href=#>press it where small flower is situated on an page</a></h1>
      </div>
    </body>

Let me give you an example. So I need DIFFERENT WEBLINKS when orange flower was pressed or a blue one and third different weblink for white flowers and so on. If it is one screen I just divide it for some virtual squares but it absolutely rubbish to do so for many different resolutions: https://gessoemsp.org/wp-content/uploads/2013/08/lovely-small-flower-garden-plans.jpg

You need to do it manually.

  1. Define the position of the flower inside your image, i.e., the area that will trigger the event when clicked.
  2. Set an event handler for the click event on the body element.
  3. Get the position of the mouse when the user clicked on the image.
  4. Compare that position with the defined area for the flower.

This answer will only work if the image is loaded within the tag. If the background image has the small flower and it moves around, you wont be able to identify when a user clicks the flower via an tag. You will need much a more sophisticated solution.

<a href="javascript:void(0);" onClick="alert('you clicked the image')">Image</a>
