This is a custom fork of the Casper theme for Ghost, created and maintained by Adriano Amalfi. It includes additional features and customizations not present in the original Casper theme.

This fork introduces the following features:

• LinkedIn Button: Option to display a LinkedIn button with a customizable account link.
• Progress Bar on Posts: A progress bar that shows reading progress on individual posts.

For more details, visit the repository.

Ghost uses a simple templating language called Handlebars for its themes.

This theme has lots of code comments to help explain what's going on just by reading the code. Once you feel comfortable with how everything works, we also have full theme API documentation which explains every possible Handlebars helper and template.

The main files are:

• default.hbs - The parent template file, which includes your global header/footer
• index.hbs - The main template to generate a list of posts, usually the home page
• post.hbs - The template used to render individual posts
• page.hbs - Used for individual pages
• tag.hbs - Used for tag archives, eg. "all posts tagged with news"
• author.hbs - Used for author archives, eg. "all posts written by Jamie"

One neat trick is that you can also create custom one-off templates by adding the slug of a page to a template file. For example:

• page-about.hbs - Custom template for an /about/ page
• tag-news.hbs - Custom template for /tag/news/ archive
• author-ali.hbs - Custom template for /author/ali/ archive

Casper styles are compiled using Gulp/PostCSS to polyfill future CSS spec. You'll need Node, Yarn and Gulp installed globally. After that, from the theme's root directory:

# install dependencies
yarn install

# run development server
yarn dev

Now you can edit /assets/css/ files, which will be compiled to /assets/built/ automatically.

The zip Gulp task packages the theme files into dist/<theme-name>.zip, which you can then upload to your site.

# create .zip file
yarn zip

• Autoprefixer - Don't worry about writing browser prefixes of any kind, it's all done automatically with support for the latest 2 major versions of every browser.
• Color Mod

Casper uses inline SVG icons, included via Handlebars partials. You can find all icons inside /partials/icons. To use an icon just include the name of the relevant file, eg. To include the SVG icon in /partials/icons/rss.hbs - use {{> "icons/rss"}}.

You can add your own SVG icons in the same manner.
