How do I adjust this custom <li> content as intended

Question

Above is a mockup of the content that I am trying to replicate.

Here is what I have right now:

below are my <ul> and <li> with CSS but I cannot exactly replicate what is in the mockup even if I use padding or margin:

ul {
  padding: 0;
  list-style: none;
}

#b1::before {
  content: "• ";
  color: #B1B1B1;
}

#b2::before {
  content: '|';
  color: #B1B1B1;
  margin-bottom: 20px;
}

<ul>
  <li id="b1">Introduction</li>
  <li id="b2"></li>
  <li id="b1">Disclaimers</li>
  <li id="b2"></li>
  <li id="b1">Preservation of Immunities</li>
  <li id="b2"></li>
  <li id="b1">General</li>
</ul>

looking for another way to edit the CSS that is not padding or margin to get the design I need. Any help would be appreciated.
