Cover page with html/css code and mouse animation hover over

Site URL: http://www.fabionlus.it

hi, sorry I am not an expert

My site is www.fabionlus.it

I would like insert a new cover-page with my logo-image (file attached) with an image-map with  link in every different color. Also I would like an effect with the mouse when hover over the image link.

So I have two problems:

1) can I have a cover page with code html or css ? where is the place to insert the code?

2) I already created a page with an image-map (www.fabionlus.it/organigramma), but I don't know the code to insert for an animation when the mouse hover the link. How can I modified this code? 

<style>

  .image-overlay-wrap {
  
    display: inline-block; /* shrinks container to image size */
    fill: transparent;
    position: relative;
    
    }
    
  .image-overlay-wrap img { /* optional, for responsiveness */
  
    display: block;
    height: auto;
    max-width: 100%;
    
    }
    
  .image-overlay-wrap svg {
  
    left: 0;
    position: absolute;
    top: 0;
    
    }
    
  </style>

<div class="image-overlay-wrap">

thanks a lot and sorry for my bad English

1. You can add a Code Block > Paste HTML/CSS. Then share link to that. We can give the code to remove header,footer to make it become "cover page"

2. Which hover? Can you describe in detail?
