conditional json formatting for form footer - basic

Deleted you're using the wrong style, it should be visibility, not display:

"visibility": "=if([$Column1]=='A', 'visible', 'hidden')"

For example:

{
    "elmType": "div",
    "style": {
        "width": "100%",
        "text-align": "left",
        "overflow": "hidden",
        "border-top-width": "1px"
    },
    "children": [
        {
            "elmType": "div",
            "style": {
                "height": "15px",
                "width": "100%",
                "color": "#fff",
                "font-size": "13px",
                "border-top": "5px solid #eee",
                "background-color": "orange",
                "padding": "10px",
                "visibility": "=if([$Column1]=='A', 'visible', 'hidden')"
            },
            "children": [
                {
                    "elmType": "div",
                    "txtContent": "=if([$Column2] == '1' ||[$Column2] == '2', ' Dog ', 'Cat')"
                }
            ]
        }
    ]
}
