Manual File-System Install (/content/themes) & Permissions

2. Set ownership and permissions to match your Ghost user.

3. Activate the theme via the Ghost Admin dashboard under Settings > Design.

4. Restart Ghost if necessary.

Ghost Theme Anatomy (What You Need to Know)

package.json & Custom Settings

very Ghost theme includes a package.json file that defines the theme’s metadata and custom settings. Key properties include:

• name: Theme name
• version: Theme version number
• engines: Compatible Ghost CMS versions
• config: Custom configuration options visible in the Ghost Admin

The Casper theme, which was created by the Ghost team, is a common example where developers customize the package.json file and theme metadata.

This file allows theme developers to create configurable options accessible through the admin interface.

Handlebars Templates, Partials, Helpers

Ghost themes use Handlebars (.hbs) template files to render pages. Key components:

• Templates: Define layouts for pages, posts, tags, authors, etc.
• Partials: Reusable components such as headers, footers, and post cards.
• Helpers: Built-in functions like {{#foreach}}, {{#if}}, and custom helpers provided by the Ghost team to add dynamic content.

Ghost themes include various page templates, such as tag.hbs for tag pages, author.hbs for author pages, and a dedicated tags page to showcase articles by tag. The first tag assigned to a post is especially important, as it can be used to organize content and customize the user experience. These templates are created as individual .hbs files and are integrated into the theme structure, often working with layout files like default.hbs to ensure consistent design and functionality across different types of pages.

Understanding these is crucial for creating your own custom theme or modifying existing ones.

Customize Look & Feel (Practical How-To)

CSS Variables & Theming System (Examples)

Ghost themes often utilize CSS variables for easy theming. For example:

css :root { --primary-color: #1a73e8; --background-color: #ffffff; --text-color: #333333; }

Modify these variables in your CSS files to change colors, spacing, and other design elements without touching the core styles.

Fonts, Typography, and Dark Mode Toggle

Customize fonts and typography by editing CSS files or using Google Fonts. Implement a dark mode toggle by:

Defining light and dark CSS variables.

Adding JavaScript to switch themes on user interaction.

Using prefers-color-scheme media queries for automatic detection.

Add Functionality

Membership/Custom Paywalls (Theme Hooks)

Ghost supports memberships and paywalls through theme hooks. Use the built-in membership helpers in your templates to:

• Show/hide content based on member status.
• Customize signup forms and paywall messaging.
• Integrate with Ghost’s subscription system seamlessly.

Add Google Analytics & Consent (GDPR Notes)

To add Google Analytics:

1. Insert the GA tracking script in your theme’s header partial or use the Ghost Admin’s Code Injection feature.

2. Implement a consent banner respecting GDPR by adding a script or third-party plugin.

3. Use Ghost’s built-in privacy settings to manage data collection.
