Hello  @Namsey,
You can hide header and footer on your home page just putting the following code 
COPY CODE
@media screen and (max-width: 480px) { 
   body.home-page #header, body.home-page #footer { 
   display: none !important;
    } 
}
 
 to your the style.css file of KLEO Child Theme. You can edit the file from Appearance>Editor>Style.css. Please just copy and paste the code to the style.css file and save. Then visit your site. I have tested on my site. It works fine. Please let me know if it works for you. Thank you very much. 🙂
