I have a Shopify powered store and am trying to hide the class “hulk-powered-wrapper” on this page: https://www.palmettowoodshop.com/pages/contact-us

Screenshot showing text I want hidden

I have tried adding the code below to the css both on my contact page and my base css page, but neither work. What am I doing wrong?

.hulk-powered-wrapper {
  visibility: hidden;
  display: none;
  }
