Is there a way to only use CSS in order to make a button have the same width as a sibling button?

Question

Basically, I have two buttons that have the same style and are lined beside each other inside a parent div.

CSS grid can do this:

 body {
  text-align: center
 }
.container {
  display: inline-grid;
  grid-template-columns: 1fr 1fr;
  margin:10px;
}

.btn {
  min-height: 44px;
  max-width: 320px;
  box-sizing: border-box;
  padding: 6px 24px border-radius: 4px;
  outline: none;
  cursor: pointer;
}

.btn-primary {
  border: none;
  background-color: #808080;
  color: #FFFFFF;
}

.button1 {
  background-color: #FFFFFF;
  color: #000000;
  border: 1px solid #b6b6b6;
}

.button2 {
  margin-left: 12px;
  padding: 6px 36px;
}
