Progress bar lines disappears CSS - html

Question

I have this progressbar and when it stands outside the <header> the lines between the steps is showing, but because of a needed z-index the lines doesn't show when its inside the <header> tag.
Like this:
If I change the z-index the line goes through the boxes like this:
I don't know if there's a workaround this, but if you have any ideas, please let me know!
My code for the relevant parts:
body {
background: #000;
}
header {
background-image: url("http://texturemate.com/image/view/1560/_original");
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: 100%;
height: 2px;
background: white;
position: absolute;
left: -50%;
top: 25px;
z-index: -1; /*put it behind the numbers*/
}
#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;
}

You can decrease the width of lines then adjust Left position to put it between circles ( from outer border of circles not from center ), also don't forget to set z-index: 1 for lines.
Something like this:
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;
}
