Как я могу устранить проблему непрозрачности навигационного меню?

Question

Я вставил код здесь:

https://jsfiddle.net/JTBennett/sdydw4L6/ [CSS - FadeIn материал в верхней части, нав вещи на дне]

но копировать + вставить следующий, если вы хотите увидеть реальную проблему в браузер ... jsfiddle исправляет это как-то.

HTML:

<header class="masthead" style="z-index:9999; top:30%;"> 
    <nav> 
    <div class="nav-container"> 
     <div id="fadein-menu-1"> 
     <input id="slider1" name="slider1" type="checkbox"> 
     <label class="slide has-child" for="slider1"> 
      <span class="element">Vi</span>

Это на самом деле работает очень хорошо в jsfiddle, но когда я запускаю его в браузере есть проблема с меню ребенка Полномостовые по умолчанию (верхнее выравнивание), оставшееся при 0 непрозрачности. То же самое происходит в Chrome и Safari, и почти наверняка это проблема с непрозрачностью, которая не разрешилась после команд анимации, но кажется странным, что это происходит только с дочерним меню по умолчанию. Если вы удалите непрозрачность: 0; строки из идентификатора # fadein-menu-1/2/3/4, подменю снова работает.

Я чувствую, что мне просто не хватает одной вопиющей, тупой мелочи ... но я не могу найти ее для жизни. Было бы очень полезно помочь здесь.

Answer 1

Проблема:

animation: fadein 1s ease-in 1.4s 1 forwards; 

Вы пытаетесь выцветанию в элементе, который имеет opacity:0;. Ваша анимация запускается, как только элемент затухает, а затем элемент возвращается к стилю по умолчанию (opacity:0;). Таким образом, вы не можете видеть эти элементы.

Решение: удалить непрозрачность по умолчанию.

#fadein-menu-1 { 
    /* Remove from all the elements */ 
    //opacity:0; 
    -webkit-animation: fadein 1s ease-in 1s 1 forwards; /* Safari, Chrome and Opera > 12.1 */ 
     -moz-animation: fadein 1s ease-in 1s 1 forwards; /* Firefox < 16 */ 
     -ms-animation: fadein 1s ease-in 1s 1 forwards; /* Internet Explorer */ 
     -o-animation: fadein 1s ease-in 1s 1 forwards; /* Opera < 12.1 */ 
      animation: fadein 1s ease-in 1s 1 forwards; 
}
