Appreciate if someone can give custom codes for custom.css to remove header and footer advertisements here: https://carnity.com/login/

.ipsApp_front[data-pageapp="core"][data-pagemodule="system"][data-pagecontroller="login"] .adsbygoogle 
{
  display: none!important; 
}

Should work. The !important bit is needed because google has an inline display:block; style on the wrapper elements of the ads in question.
