進度條線條消失CSS

我有這個進度條，當它站在<header>之外時，步驟之間的界線正在顯示，但由於需要z-index，線條不會在<header>標籤內顯示其內容。像這樣：進度條線條消失CSS

如果我改變z-index直線穿過盒子這樣的：

我不知道是否有一個變通方法，但如果您有任何意見，請讓我知道！

我對相關的部分代碼：

body { 
 
    background: #000;

header { 
 
    background-image: url("http://texturemate.com/image/view/1560/_original"); 
 
    background-repeat: no-repeat; 
 
    background-size: cover; 
 
    padding: 0;

     margin: 50px auto; 
 
     text-align: center; 
 
     position: relative; 
 
    } 
 

 
    /*progressbar*/ 
 
    #progressbar { 
 
     margin-bottom: 30px; 
 
     overflow: hidden; 
 
     /*CSS counters to number the steps*/ 
 
     counter-reset: step;

您可以編輯您的示例代碼，以便它顯示了問題？你的代碼中甚至沒有'header'元素。 – Turnip

任何理由不通過'Z-index'進一步發暗的背景？ – Nitesh

我到現在的代碼添加的頭元素，@Turnip – teninchhero

可以減少線路的width然後調整Left位置，把它圈之間（從社交圈的外邊框不是從中心），也不要忘記設置z-index: 1的線路。

事情是這樣的：

body { 
 
    background: #000; 
 
} 
 

 
header { 
 
    background-image: url("http://www.solidbackgrounds.com/images/2880x1800/2880x1800-air-force-dark-blue-solid-color-background.jpg"); 
 
    background-repeat: no-repeat; 
 
    background-size: cover; 
 
    padding: 0; 
 
} 
 

 
/*form styles*/ 
 
#msform { 
 
    width: 400px; 
 
    margin: 50px auto; 
 
    text-align: center; 
 
    position: relative; 
 
} 
 

 
/*progressbar*/ 
 
#progressbar { 
 
    margin-bottom: 30px; 
 
    overflow: hidden; 
 
    /*CSS counters to number the steps*/ 
 
    counter-reset: step; 
 
} 
 

 
#progressbar li { 
 
    list-style-type: none; 
 
    color: white; 
 
    text-transform: uppercase; 
 
    font-size: 9px; 
 
    width: 33.33%; 
 
    float: left; 
 
    position: relative; 
 
} 
 

 
#progressbar li:before { 
 
    content: counter(step); 
 
    counter-increment: step; 
 
    width: 50px; 
 
    line-height: 50px; 
 
    display: block; 
 
    font-size: 10px; 
 
    color: #333; 
 
    background: white; 
 
    border-radius: 50%; 
 
    margin: 0 auto 5px auto; 
 
} 
 

 
/*progressbar connectors*/ 
 
#progressbar li:after { 
 
    content: ''; 
 
    width: 60%; /* Changed */ 
 
    height: 2px; 
 
    background: white; 
 
    position: absolute; 
 
    left: -30%; /* Changed */ 
 
    top: 25px; 
 
    z-index: 1; /* Changed */ 
 
} 
 

 
#progressbar li:first-child:after { 
 
    /*connector not needed before the first step*/ 
 
    content: none; 
 
} 
 

 
/*marking active/completed steps green*/ 
 
/*The number of the step and the connector before it = green*/ 
 
#progressbar li.active:before, #progressbar li.active:after{ 
 
    background: #27AE60; 
 
    color: white; 
 
}

    <div class="container">
