Why is font-family not inherited for some blocks?

Question

1C

Problem: css property "font-family: 'PT Sans', sans-serif;" works as it should only for the header and footer, for some reason the section tags are set to the font "sans-serif", and not "PT Sans". Those. I can't understand why the first specified font is inherited and found for the footer and header, but not for the rest of the tags.
Here is part of the CSS code, followed by classes.

html {
    box-sizing: border-box;
}

* {margin: 0px;
    padding: 0px;
    box-sizing: inherit;
}

body {
    background-color: #212b4f;
    color: #ffffff;
    font-family: 'PT Sans', sans-serif;
  font-size: 15px;
  font-weight: 400;
  line-height: 20px;
}

img {
    max-width: 100%;
    height: auto;
}

.page-footer {
    color: white;
    background-color: #212b4f;
}

a {
    text-decoration: none;
    color: inherit;
}
