Custom Site Title by page

Site URL: http://www.bulldog-tomato-c98d.squarespace.com

Hello, I have a question about what CSS is needed to customize my site. I created what is essentially a landing page and hid the header navigation and social sections but now I cannot figure out how to center my site title. I only want to center the site title on this one page not the entire website.

Thanks for all the help in advance!!

First, edit page > Add a Code Block (any where) > Paste this code

<style>
.header-title-nav-wrapper {
    flex-direction: column;
    flex: 1 0 100% !important;
    width: 100% !important;
}
  .header-title {
    text-align: center;
}
</style>
