Describe the issue

Numbered lists with a start attribute as offset do not count correctly. For example

<ol class="list-group list-group-numbered" start=10>
  <li class="list-group-item">ten</li>
  <li class="list-group-item">eleven</li>
</ol>

start counting from 1

Reduced test cases

A second value for counter-reset fixes the offset, but I do not know how to set this dynamically:

ol.list-group-numbered[start] {
  counter-reset:section 9;
}

Sorry, its not about <ol>s its about the CSS class .list-group-numbered which cannot have a offset right now. As long as its documented I'm ok with it.

My two cents! We can use CSS variables.

<ol start="10" class="list-group list-group-numbered" style="--list-start: 10;">
  <li class="list-group-item">list item</li>
  <li class="list-group-item">list item</li>
  <li class="list-group-item">list item</li>
  <li class="list-group-item">list item</li>
</ol>

.list-group-numbered {
  counter-reset: section var(--list-start, 0) !important;
}

<ol start="10" class="list-group list-group-numbered" style="--list-start: 10;">
  <li class="list-group-item">list item</li>
  <li class="list-group-item">list item</li>
  <li class="list-group-item">list item</li>
  <li class="list-group-item">list item</li>
</ol>

.list-group-numbered {
  counter-reset: section var(--list-start, 0) !important;
}

Ok. Your solution is a good idea but you need a -1. Here you can see how: https://codepen.io/matedon/pen/LYqjJVm .list-group-numbered { counter-reset: section calc(var(--list-start, 1) - 1) !important; }
