Media Query for H1 displaying different from tablet to full screen

Site URL: http://flowerwalldubai.squarespace.com

Hello, 

Please could someone help me? I've entered the below custom CSS to stop the 'Welcome to' and 'Flowerwall Dubai' text from overlapping, this works fine on tablet and mobile view but has a large space in between on full screen?

I'm not sure what to do now? 😥

@media screen and (max-width: 641px) {
body { font-size: 11pt;
line-height: 20px;
  text-align: center;}
 
h1 {font-size: 30pt;
  padding: 10px;
  }
h2 {font-size: 30pt;
  font-weight: 400;
  text-align: center;}
h3 {font-size: 16pt}
  #block-2e9f5306c508fa38a436, #block-yui_3_17_2_1_1579636239796_16990 {
    top: 100px;
    padding-top:40px;
   
  }

  #block-yui_3_17_2_1_1579640268463_14758 {
    top: 30px;}
  
}

@media screen and (min-width: 751px) {
body { font-size: 11pt;
line-height: 20px;
  text-align: center;}
 
h1 {font-size: 30pt;
  padding: 10px;
  }
h2 {font-size: 30pt;
  font-weight: 400;
  text-align: center;}
h3 {font-size: 16pt}
  #block-2e9f5306c508fa38a436, #block-yui_3_17_2_1_1579636239796_16990 {
    top: 100px;
    padding-top:40px;
   
  }
  #block-2e9f5306c508fa38a436 { 
  top: -30px;}
  
  #block-yui_3_17_2_1_1579640268463_14758 {
    top: -50px;} 
  
}
.Mobile-overlay-nav-item, .Mobile-overlay-folder-item { text-align: center;
}

Can you take screenshot of "overlapping"? See fine here?
