Здравствуйте.
Помогите пожалуйста разобраться, что ни так.
Нужно блок с классом cro-checkout-trustsection, добавить после класса block, и нужно именно на js.
Добавляю такой код, выдает ошибку
document.getElementById('block').classList.add('cro-checkout-trustsection');
Если кому надо на jQuery, то это будет так
var newElems = $("<div class='cro-checkout-trustsection'></div>")
.append('<div class="cro-checkout-trustsection-title">Você pode pagar com:</div>')
newElems.css("border", "1px solid rgb(229, 229, 229)");
$('.block').append(newElems);
