Progress bar doesn't get active at step 1 - html

Question

I'm very new into coding and I wanted to add a progress bar on my website. But when I want to make the step1 "active", it's the step2 that gets active (and when I make the step 2 active, it's the step 3 that gets active and so on)
<div id="fh5co-work">
<div class="row">
<div class="col-md-8">
<div class="root">
<div class="container">
<ul class="progressbar">
<li class="active">Step 1</li>
<li>Step 2</li>
<li>Step 3</li>
<li>Step 4</li>
<li>Step 5</li>
</ul>
</div>
</div>
Here's the css code in the bootstrap.css:
.container{
width: 140%;
position: absolute;
z-index: 1;
}
.progressbar li{
float: left;
width: 20%;
position: relative;
text-align: center;
}
.progressbar li:before{
content:"1";
width: 30px;
height: 30px;
border: 2px solid #bebebe;
display: block;
margin: 0 auto 10px auto;
border-radius: 50%;
line-height: 27px;
background: white;
color: #bebebe;
text-align: center;
font-weight: bold;
}
.progressbar{
counter-reset: step;
}
.progressbar li:before{
content:counter(step);
counter-increment: step;
width: 30px;
height: 30px;
border: 2px solid #bebebe;
display: block;
margin: 0 auto 10px auto;
border-radius: 50%;
line-height: 27px;
background: white;
color: #bebebe;
text-align: center;
font-weight: bold;
}
.progressbar li:after{
content: '';
position: absolute;
width:100%;
height: 3px;
background: #37606f;
top: 15px;
left: -50%;
z-index: -1;
}
.progressbar li:first-child:after{
content: none;
}
.progressbar li.active + li:after{
background: #37606f;
}
.progressbar li.active + li:before{
border-color: #37606f;
background: #37606f;
color: white
}
What can I do to make it work?

Answer 1

When I changed the style definition .progressbar li.active + li:before in css to .progressbar li.active:before, the problem went away.
.container{
width: 140%;
position: absolute;
z-index: 1;
}
.progressbar li{
float: left;
width: 20%;
position: relative;
text-align: center;
}
.progressbar li:before{
content:"1";
width: 30px;
height: 30px;
border: 2px solid #bebebe;
display: block;
margin: 0 auto 10px auto;
border-radius: 50%;
line-height: 27px;
background: white;
color: #bebebe;
text-align: center;
font-weight: bold;
}
.progressbar{
counter-reset: step;
}
.progressbar li:before{
content:counter(step);
counter-increment: step;
width: 30px;
height: 30px;
border: 2px solid #bebebe;
display: block;
margin: 0 auto 10px auto;
border-radius: 50%;
line-height: 27px;
background: white;
color: #bebebe;
text-align: center;
font-weight: bold;
}
.progressbar li:after{
content: '';
position: absolute;
width:100%;
height: 3px;
background: #37606f;
top: 15px;
left: -50%;
z-index: -1;
}
.progressbar li:first-child:after{
content: none;
}
.progressbar li.active + li:after{
background: #37606f;
}
.progressbar li.active:before{
border-color: #37606f;
background: #37606f;
color: white
