Answer 1

Le long chemin:

$('input:radio').click(function() { 
    if($(this).is(':checked')) { 

     //select the main div wrapping this radio 
     $(this).parent().parent().addClass('.label_main_selected'); 

     //or you can do 
     //$(this).closest('.label_main').addClass('.label_main_selected'); 
    } else { 
     $(this).parent().parent().removeClass('.label_main_selected'); 
     //or $(this).closest('.label_main').removeClass('.label_main_selected'); 
    } 
}); 

La façon courte (peut ou peut ne pas convenir à cet effet, dépend de exactement ce que vous êtes après):

$('input:radio').click(function() { 
    $(this).parent().parent().toggleClass('.label_main_selected'); 
    //or $(this).closest('.label_main').toggleClass('.label_main_selected'); 
});

$(document).ready(function(){ 
 
    $("input:radio").click(function(){ 
 
     if ($(this).is(":checked")){ 
 
     $("label").css({"color":"green","background-color":"#6600cc"}) && $(this).closest("label").css({"color":"green","background-color":"orange"}); 
 
     } 
 
    }); 
 
});

input[type=radio], 
 
    input[type=checkbox] { 
 
     display: none; 
 
    } 
 
label { 
 
color:white; 
 
font-size:48px; 
 
}
