How to center html "ul" element in bootstrap4 (horizontal + vertical) with horizontal aligned "li"
<section>
<div class='row'>
<div class='col-sm'>
<ul>
<li>A</li>
<li>B</li>
<li>C</li>
</ul>
</div>
</div>
</section>
If you use this code the list will be displayed in the center of the yellow box. I don't know why it won't work on the code preview on stackoverflow, but here you can see that it works.
<section>
<div class='row'>
<div class='col-sm' style="background-color: yellow; display:grid;height: 100%">
<ul style="margin: center;">
<li>A</li>
<li>B</li>
<li>C</li>
</ul>
</div>
</div>
