Main elements in html

<%= @topic_view.topic.title %>
<%= @topic_view.topic.average_rating %> <%= @topic_view.topic.posts.count { |p| !!p.custom_fields['rating'] } %>

The main element should have two paragraph elements as children.
I will like to know how to do that.will some one show me ?am new here

this <div> has a child element:

<div id = "parent">
     <h2 id = "child">I am an h2!</h2>
</div>

Sometimes, tags may also have “grandchildren”

<div id = "parent">
     <span id = "child">
          <h3 id = "grandchild">I am an h3!</h3>
     </span>
</div>

Do you see the pattern here?
An <h1> is nested inside of a <main> tag. which is the child?

Solution
<main>
     <p>[text]</p>

     <p>[text as well]</p>

</main>
