Custom CSS timeline with odd / even styling - html

Question

I want to remove the first line from the CSS timeline I created, I just want the timeline circle to show up first not to have a line before it. I also want to style each dot different color, how can I do both these?
I have tried to add a class to one of the timeline containers called .not_complete but it doesnt change the color of the circle of the timeline.
/* The actual timeline (the vertical ruler) */
.timelinex {
position: relative;
max-width: 1200px;
margin: 0 auto;
padding-bottom: 5em;
}
/* The actual timeline (the vertical ruler) */
.timelinex:before {
content: '';
position: absolute;
width: 0px;
background-color: #fff;
top: auto;
bottom: 0;
left: 50%;
margin-left: -3px;
}
.timelinex::after {
content: '';
position: absolute;
width: 4px;
background-color: #e3e3e3;
top: 0;
bottom: 0;
left: 50%;
margin-left: -3px;
}
/* Container around content */
.containerx {
padding: 10px 40px;
position: relative;
background-color: inherit;
width: 50%;
}
/* The circles on the timeline */
.containerx::after {
content: '';
position: absolute;
width: 12px;
height: 12px;
right: -5px;
background-color: #e3e3e3;
top: 15px;
border-radius: 50%;
z-index: 1;
}
.containerx::after .not_complete {
background-color: #e3e3e3 !important;
}
/* Place the container to the left */
.leftx {
left: 0;
}
/* Place the container to the right */
.rightx {
left: 50%;
}
/* Fix the circle for containers on the right side */
.rightx::after {
left: -7px;
}
/* The actual content */
.contentx {
padding: 2px 3px;
position: relative;
border-radius: 6px;
}
<div class="timelinex">
<div class="containerx leftx not_complete">
<div class="contentx">
<p>
<img src="assets/img/therapist1.jpg" style="border-radius: 0.5em;border-top-left-radius: 120px; border-bottom-right-radius: 120px">
</p>
<h5 style="color:#999;font-style: 0.5em"> DAY 1 </h5>

Answer 1

The selector here is invalid:
.containerx::after .not_complete {
It would select the child of the ::after pseudo element. You need to use:
.containerx.not_complete::after {
The above selector selects any element's ::after pseudo element, with the classes containerx and not_complete. So kindly replace your code with:
.containerx.not_complete::after {
background-color: #e3e3e3 !important;
}
Hope this solves your issue.

Update: For Even / Odd Styling and First Child.
To create odd and even styling, you need to use :nth-child() selector. An example of having it blue and red is here:
li {
display: block;
width: 200px;
padding: 10px;
color: #fff;
}
li:nth-child(odd) {
background: #00f;
}
li:nth-child(even) {
background: #f00;
}
li:first-child {
background: #000;
font-weight: bold;
}
<ul>
<li>First Child</li>
<li>Even</li>
<li>Odd</li>
<li>Even</li>
<li>Odd</li>
</ul>
