📑 Yield and content_for for Flexible Sections​

Use yield to render the main content and content_for to define extra regions such as sidebars or page-specific scripts. This keeps your layout flexible and organized.

<!-- in application.html.erb -->
<body>
  <header>My Header</header>
  <aside><%= yield :sidebar %></aside>
  <main><%= yield %></main>
  <footer>My Footer</footer>
  <%= yield :scripts %>
</body>
<!-- in a view: app/views/posts/index.html.erb -->
<% content_for :sidebar do %>
  <p>Recent Posts</p>
<% end %>

<h1>All Posts</h1>
