Handlebars Templating

Basic Template Structure

{{!< default}}

<main class="site-content">
  {{#foreach posts}}
    {{> post-card}}
  {{/foreach}}

  {{pagination}}
</main>

Default Layout (default.hbs)

<!DOCTYPE html>
<html lang="{{@site.locale}}">
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <title>{{meta_title}}</title>

  {{ghost_head}}

  <link rel="stylesheet" href="{{asset "css/screen.css"}}">
</head>
<body class="{{body_class}}">

  {{> header}}

  {{{body}}}

  {{> footer}}

  {{ghost_foot}}

  <script src="{{asset "js/main.js"}}"></script>
</body>
</html>

Partials

{{!-- partials/post-card.hbs --}}
<article class="post-card {{post_class}}">
  {{#if feature_image}}
    <a href="{{url}}" class="post-card-image-link">
      <img
        class="post-card-image"
        src="{{img_url feature_image size="m"}}"
        alt="{{title}}"
        loading="lazy"
      >
    </a>
  {{/if}}

  <div class="post-card-content">
    <h2 class="post-card-title">
      <a href="{{url}}">{{title}}</a>
    </h2>

    {{#if excerpt}}
      <p class="post-card-excerpt">{{excerpt words="30"}}</p>
    {{/if}}

    <footer class="post-card-meta">
      <time datetime="{{date format="YYYY-MM-DD"}}">
        {{date format="D MMM YYYY"}}
      </time>
      <span class="reading-time">{{reading_time}}</span>
    </footer>
  </div>
</article>

:root {
  --ghost-accent-color: {{@site.accent_color}};
}

.accent-bg {
  background-color: var(--ghost-accent-color);
}
