Font size of inline element creates gaps in HTML-CodePudding

Notice the vertical gaps caused by a small font size. There's no padding or margin yet there's a gap and this is incredibly annoying. I'd like to remove all vertical gaps and I want to keep wrap line functionality, and the child elements should retain their original height.

.container {
  border: 1px solid black;
}

.sub-container {
  border: 1px solid black;
  display: inline-flex;
  flex-direction: column;
}

.big-child {
  display: inline-block;
  font-size: 2em;
  border: 1px solid black;
}

.small-child {
  display: inline-block;
  font-size: 0.5em;
  border: 1px solid black;
}
