title: How to add transparent button inside image with pop-up menu
body: <p>Im having this image in one of my pages
  <a href="https://i.stack.imgur.com/yvnZ2.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/yvnZ2.jpg" alt="enter image description here"></a></p>
  
  <p>I want to create the middle house "clickable" or something like transparrent or hidden button over it, so when i click on the house it will pop-up a small menu with "Go inside" or "Cancel" options.
  So far i have only this code</p>
  
  <pre><code> &lt;div class="image-holder" style="padding-left: 1px"&gt;
                      &lt;img src="../images/city.jpg" /&gt;
                      &lt;div&gt;
                          &lt;asp:Button ID="Button1" runat="server" Text="Button" /&gt;
                      &lt;/div&gt;
                  &lt;/div&gt;
  </code></pre>
  
  <p>I tried moving the button with the Design View but still not able to do it. Any help will be appreciated.</p>
