CSS Text Node Orientation

I am working on CSS for a container object. I mainly work. In particular, I look at test cases 1, 2, and 3. Everyone has text nodes. Is there a way to handle node text just like any child?

Is there a way to customize CSS to make text nodes and its siblings work well? Ban on using a CSS selector that will select .containerif there is one only if there is node text, so I can display: none(or something nicer, but still let the developer know that things aren't working)?

Here is the Codepen .

code,
p,
quote {
  display: block;
  position: relative;
  margin: 0;
  padding: 1em;
  border: 1px solid black;
  box-sizing: border-box;
}
code {
  background-color: #ccc;
}
p {
  background-color: #0df;
}
quote {
  background-color: #fd0;
}
quote::after {
  display: table;
  clear: both;
  content: "";
}
.hidden {
  display: none;
}
.third {
  height: 100%;
  width: 33%;
  float: left;
  border: 1px solid black;
}
.container {
  display: block;
  position: relative;
  margin-right: 0;
  margin-left: 0;
  margin-top: 1.5em;
  margin-bottom: 1.5em;
  padding: 0.5rem;
  border: 1px solid black;
  box-sizing: border-box;
  border-radius: 10px;
  box-shadow: none;
}

  margin-top: 0.5rem;
  margin-bottom: -0.5rem;
