In Bootstrap 5, the class btn-block
doesn't work anymore. But instead, you can add the class w-100
to the button to make it as wide as its container.

<div class="row"><div class=" col-5 ">
<a class="btn btn-outline-primary w-100 " href="# "><span>Button 1</span></a>
</div><div class="col-5 ">
<a class=" btn btn-primary w-100 weiss " href="# "><span>Button 2</span></a>
</div></div>
