Step Progress Bar Icons - css

Question

I'm trying to set up a little step progress bar that only has an icon for the current step. I've gotten so far as to have a default icon of sorts, but can't figure out how to clear it for non-active steps.
In the code below, I tried playing with pseudo classes but that didn't seem to work. I'm wondering if anyone can point me in the right direction. Thanks!
.step-indicator-container {
width: 600px;
margin: 100px auto;
}
.step-indicator li {
list-style-type: none;
width: 33.33%;
float: left;
font-size: 12px;
position: relative;
text-align: center;
text-transform: uppercase;
color: #7d7d7d;
}
.step-indicator li:before {
font-family: "FontAwesome";
content: "\f276";
width: 30px;
height: 30px;
line-height: 30px;
border: 2px solid #7d7d7d;
display: block;
text-align: center;
margin: 0 auto 10px auto;
border-radius: 50%;
background-color: white;
}
.step-indicator li:after {
width: 100%;
height: 2px;
content: "";
position: absolute;
background-color: #7d7d7d;
top: 15px;
left: -50%;
z-index: -1;
}
.step-indicator li:not(.active):nth-of-type(2) > *::before {
content: none;
}
.step-indicator li:first-child:after {
content: none;
}
.step-indicator li.active {
color: #0052e7;
}
.step-indicator li.active:before {
border-color: #0052e7;
}
.step-indicator li.active+li:after {
background-color: #0052e7;
}

Answer 1

For this answer, I am assuming the following is your HTML structure:
<div class="step-indicator-container">
<ul class="step-indicator">
<li></li>
<li class="active"></li>
<li></li>
</ul>
</div>
The issue is with the following declaration:
.step-indicator li:not(.active):nth-of-type(2) > *::before {
content: none;
}
This is targeting the ::before of a descendant of the li tag. However, you actually put your symbol on the ::before of the li tag itself, not a descendant. Therefore, that's what you need to be targeting. Furthermore, content: none eliminates the ::before, so you actually want content: "". Here's what I think you actually want:
.step-indicator li:not(.active)::before {
content: "";
}
And here's the full code snippet (note I replaced your symbol with the $):
.step-indicator-container {
width: 600px;
margin: 100px auto;
}
.step-indicator li {
list-style-type: none;
width: 33.33%;
float: left;
font-size: 12px;
position: relative;
text-align: center;
text-transform: uppercase;
color: #7d7d7d;
}
.step-indicator li:before {
content: "$";
width: 30px;
height: 30px;
line-height: 30px;
border: 2px solid #7d7d7d;
display: block;
text-align: center;
margin: 0 auto 10px auto;
border-radius: 50%;
background-color: white;
}
.step-indicator li:after {
width: 100%;
height: 2px;
content: "";
position: absolute;
background-color: #7d7d7d;
top: 15px;
left: -50%;
z-index: -1;
}
.step-indicator li:not(.active)::before {
content: "";
}
.step-indicator li:first-child:after {
content: none;
}
.step-indicator li.active {
color: #0052e7;
}
.step-indicator li.active:before {
border-color: #0052e7;
}
.step-indicator li.active+li:after {
background-color: #0052e7;
}
<div class="step-indicator-container">
<ul class="step-indicator">
<li></li>
<li class="active"></li>
<li></li>
</ul>
</div>
