How to correctly set the markup with classes for a multi-page site?

Question

HTML

spoiler

Let's say there are 38 such pages, only the text under the heading will change.

How is it generally more correct to set styles, my example, and how is it more correct?

<div class="row wrapper">
  <aside class="sidebar"></aside>
  <div class="wrapper">
    <header class="header"></header>
    <main class="page">
      <div class="content">
        <div class="content__header">
          <h1 class="title">Основы <span class="title__subtext">Наши ценности</span></h1>
        </div>
        <div class="content__info"></div>
      </div>
    </main>
    <footer class="footer"></footer>
  </div>
</div>

More correctly content_header or page_header and aside inside main or because it repeats undesirable inside to be ?
