A handy CSS snipped I use for all my Unbounce pages.

<!-- Remove link styling and a class to center on mobile -->
<style type="text/css">  
 
#lp-pom-root .lp-pom-text a:link {text-decoration: none}
#lp-pom-root .lp-pom-text a:visited {text-decoration: none}
#lp-pom-root .lp-pom-text a:active {text-decoration: none}
#lp-pom-root .lp-pom-text a:hover {text-decoration: none}

@media screen and (max-width: 600px) {
  .mobile-centered { 
    text-align: center !important;
  }
}  

</style>

There’s also this smooth scroll script

<!-- Smooth Scroll jQuery 2.2.4 -->
<script>
  jQuery($ => {
    // The speed of the scroll in milliseconds
    const speed = 1000;

    $('a[href*="#"]')
      .filter((i, a) => a.getAttribute('href').startsWith('#') || a.href.startsWith(`${location.href}#`))
      .unbind('click.smoothScroll')
      .bind('click.smoothScroll', event => {
        const targetId = event.currentTarget.getAttribute('href').split('#')[1];
        const targetElement = document.getElementById(targetId);

        if (targetElement) {
          event.preventDefault();
          $('html, body').animate({ scrollTop: $(targetElement).offset().top }, speed);
        }
      });
  });
</script>
