Is the blog layout correct?

Question

css

Do I understand correctly that such a layout system should be organized on flex? So the hierarchy is:

<div class="wrapper">
  <div class="main-block">Тут весь широкий блок</div>
  <div class="right-block">Тут блок,что справа, длинный узкий</div>
<i>На классы внимания не обращайте, для вида написал</i>
</div>

And after layout, put display:flex on the wrapper, etc.
Am I thinking right? I just did this before, if the blocks are small, but here they are on the whole page.

Answer 1

Correctly.
