CSS for particular Table

In the Old version we can write prticular Table CSS as

.tablename>.container-fluid,.menuhome>.content{
     padding-right:0!important;
     padding-left:0!important
}

But in PHPMaker 2024 the class tablename has remove.
Now I have created a Custom File with the name “menuhome.php”
How can write a CSS code only for this page using the above code.

Menu is for all pages, it is not placed under a HTML element with class named with a table name, not in any versions. However, you can add your own class to Config("BODY_CLASS") in server events such as Page_Render. Also see global functions for more info about Config().

Sorry my mistake “menuhome.php” is a custom file which I have crated in my case.
now let us take another example “mycustomfile.php”
is there any way to use in the css under HTML->Style->User like

.mycustomfile>.container-fluid,.mycustomfile>.content{
     padding-right:0!important;
     padding-left:0!important
}

Custom Files support Page_Render server event.
