Помогите найти ошибку в коде ReferenceError: invalid assignment left-hand side в js

Вот код:

var fogot = true,counter = 0;
for (var j = 0; j <= $('.flex-dir-row .one-good').length; j++) {
    alert(0);
    if((j % (2*6)) == 0){
        $(".goods-container").css("height") = (parseInt($(".goods-container").css("height")) + 100) + "%";
    }
}
$(".slide-button").click(function(){
    if(counter <= Math.floor(j/12)){
        $(".goods-container").css({"animation":"moveToTop 1s linear forwards"});
        counter++;
        alert(1);
    } else {
        $(".goods-container").css({"animation":"moveToBottom 1s linear forwards"});
        counter--;
        alert(0);
    }
});
