How can CSS be used to apply styling to elements based on their position using the nth-child pseudo-class (Snake Wrap)?

My goal is to apply CSS in order to style two layouts, using pseudo-classes, but other suggestions are welcome as well. The first layout has been styled as expected, but I'm struggling to style the second layout. Additionally, each div in the second layout needs to be connected by a dashed line, which I believe can be achieved using the :before and :after pseudo-classes. I would appreciate any help you can provide with this. You can see the second layout image below for reference:

enter image description here

If you're generating code, you should enclose every piece of code you write within 
 tags, as the output you provide is written to an HTML file on the front end. Therefore, you must produce an output that is suitable for this purpose. Here is the code for the first layout:




  

    
01
  

  
    
02
  

  
    
03
  

  
    
04
  

  
    
05
  

  
    
06
  

  
    
07
  

  
    
08
  

  
    
09
  

  
    
10
  






And the CSS styling for the first layout:


/* 01st layout */

.item {
  display: flex;
}

.child {
  background: red;
}


/* 1st */

.row .item:nth-child(4n+1) {
  justify-content: start;
}


/* 2nd */

.row .item:nth-child(2n) {
  justify-content: center;
}


/* 3rd */

.row .item:nth-child(4n+3) {
  justify-content: end;
}

For the second layout, you can achieve the desired effect by making a few CSS changes and adding a pseudo-element to each item. Here's an example of how you can modify the code:

.item {
  display: block;
  margin-bottom: 20px;
  text-align: center;
  position: relative;
}

.item:after {
  content: "";
  position: absolute;
  left: 50%;
  top: 0;
  transform: translateX(-50%);
  width: 1px;
  height: 100%;
  background-color: #ccc;
}

.item:last-child:after { /* remove the last dotted line */
  display: none;
}

.child {
  background: red;
  width: 100px;
  height: 100px;
  margin: 10px auto;
  border-radius: 50%;
  display: flex;
  align-items: center; /* center the content inside the circle */
  justify-content: center;
  color: #fff;
  font-weight: bold;
}

In this example, we first change the display property of the .item class to block and add some margin at the bottom to separate each item. We also set the text-align property to center to center the circle and the text inside it.
Next, we add a pseudo-element to each item using the :after selector. We position it absolutely in the center of the item and use the transform property to shift it left by 50%. We set a width of 1px, a height of 100%, and a gray background to create the dashed line.
Finally, we add some styles to the .child class to center the content inside the circle and set the text color to white. We also add a font-weight property to make the text bold.
Here's the updated HTML code for the second layout:

<div class="row">
  <div class="item">
    <div class="child">01</div>
  </div>
  <div class="item">
    <div class="child">02</div>
  </div>
  <div class="item">
    <div class="child">03</div>
  </div>
  <div class="item">
    <div class="child">04</div>
  </div>
  <div class="item">
    <div class="child">05</div>
  </div>
</div>

Note that we only need to include the first five items in the HTML code, as the last dotted line is removed by the CSS rule .item:last-child:after { display: none; }.
