z-индекс для позиции: исправлено?

1 голос
/ 02 марта 2020

Скажите, пожалуйста, как применить z-index, если элемент покрытия должен иметь положение: fixed? В этом случае позиция: фиксированная; применяется для навигации, но поверх него мне нужно отобразить кнопку меню. Как это можно сделать?

Вот мой пример, правильно отображаемый на полной странице.

Ранее мне помогали объяснить, как работает z-index в этом примере, но не было такого условия как позиция: фиксированная. 

  $('#nav-btn').on('click', function () {
    $('#nav-btn').toggleClass('open');
    $('.navigation').toggleClass('is-opened');
  });
.navigation.is-opened {
    opacity: 1;
    pointer-events: auto;
    transition: opacity 0s 0s;
}

.navigation.is-opened .navigation__inner {
    -webkit-transform: translateX(0%);
    transform: translateX(0%);
}

.navigation {
    position: fixed;
    width: 100%;
    right: 0;
    top: 0;
    bottom: 0;
    opacity: 0;
    z-index: 150;
    pointer-events: none;
    overflow: hidden;
    text-align: center;
    color: #fff;
    display: block;
    transition: opacity 0s 0.3s;
    -webkit-overflow-scrolling: touch;
}

.navigation__inner {
    background-color: #0c1428;

Вы на правильном пути, просто поместите z-index в родительский контейнер, как показано ниже 

.head-panel {
    z-index: 222;
}

Поскольку head-panel является первым родителем вашего заголовка. 

$('#nav-btn').on('click', function () {
    $('#nav-btn').toggleClass('open');
    $('.navigation').toggleClass('is-opened');
  });
.navigation.is-opened {
    opacity: 1;
    pointer-events: auto;
    transition: opacity 0s 0s;
}

.navigation.is-opened .navigation__inner {
