Use Custom Classes as CSS Selectors

Use the Write ADC Data Action to assign one or more custom classes to a field. To later remove a class (e.g., after passing a validation), set the ADC Attribute ADC::Class to [NULL].

Examples

If you want to assign a custom class to a button, you must also explicitly include "nlink_button round button" as well as your custom class(es):

Depending on the control type, you may need additional CSS.

}
.NLINKControl.attention_field ,.NLINKControl.attention_field:focus {
    background-color: yellow;
}

    background-color:lightslategray;
    border-color:slategray;
}
.button.special_button:hover, .button.special_button:focus{

    border-color:gray;
}
.button.special_button[disabled], .button.special_button[disabled]:hover, .button.special_button[disabled]:focus{
