Parent font-size? How do I set the parent font-size value and then give the equivalent em font-size value?

I am confused on how to set parent sizes and their equivalent sizes.

    <title>Lake Tahoe</title>
    <link rel="stylesheet" href="page.css">

      <h1>Lake Tahoe, California</h1>

    <div class="primary-content t-border">
      <p class="intro">
        Lake Tahoe is one of the most <span>breathtaking attractions</span> located in California. It's home to a number of ski resorts, summer outdoor recreation, and tourist attractions. Snow and skiing are a significant part of the area's reputation.

Em unit is related to the parent font size, in this case, the parent of the paragraph intro is the div primary-content, since it does not have a font-size defined, the default font-size is 16px, now considering 1em = 16px, make the math and give it a font-size of 20px using ems

Since the parent font-size is 16px, which equals 1em, we then take the desired font-size of 20px, and divide 20px by 16px = 1.250em. Let's put that into our css file.

.intro {
  font-size: 1.250em;
}
