Answer 1

Make the height of the div to the right smaller than the left one, and have no margin on top/bottom. This would produce the result you are looking for

body {
  background: #eeeeee;
}
.panel {
  display: inline-block;
  background: #ffffff;
  min-height: 100px;
  height: 100px;
  padding: 10px;
}
.panel1 {
  min-width: 100px;
  width: 100px;
}
.small {
  margin-left: 10px;
  width: 111px;
  height: 90px;
  min-height: 90px;
}
.panel2 {
  min-width: 245px;
  width: 245px;
}

<div class="panel panel1">Panel 1x</div>
<div class="panel panel1 small">Panel 1x</div>
<br>
<div class="panel panel2">Panel 2x</div>
