gpscorpion1 on "How to remove class from Gateway theme body"

I want to remove the below class from the theme Gateway

class="singular page page-id-36 page-template page-template-template-full page-template-template-full-php logged-in admin-bar customize-support f-topbar-fixed"

and keep only the class "singular page page-id-36 page-template page-template-template-full page-template-template-full-php logged-in admin-bar customize-support"

because when i scroll down it creates a gap and it creates the below style that i dont want

.f-topbar-fixed {
padding-top: 135px;
}

Thank you in advance

I suppose you can just add the follow then:

.f-topbar-fixed { padding-top: 0px;
}

Custom CSS can be added with a CSS plugin like Simple Custom CSS or by activating the Custom CSS module in Jetpack:

https://wordpress.org/plugins/simple-custom-css/

https://wordpress.org/plugins/jetpack/

I have added custom css until now with FTP or from customize theme from inside wordpress. does the above you mention changes something. because i have tried before to add the style you mentioned with the ways i said and nothing happened. its like it cannot locate the class.

Still no solution. Does anyone knows how to fix this?
