Different slideshow on the homepage for mobile and desktop view

I have inserted this code into Website Tools>Code Injection>Header:

<style>
  @media only screen and (max-width: 750px) {
    .page-section:nth-of-type(1) {
        display: none;
    }
}

@media only screen and (min-width: 750px)  {
    .page-section:nth-of-type(2) {
        display: none;
    }
}
</style>

This works for the home page but also applies to every other page on the site.  Could someone help me apply this to only the home page?

Thank you! @tuanphan
