minima

Minima is a one-size-fits-all Jekyll theme for writers. It's Jekyll's default (and first) theme. It's what you get when you run jekyll new.

Disclaimer: The information here may vary depending on the version you're using. Please refer to the README.md bundled within the theme-gem for information specific to your version or by pointing your browser to the Git tag corresponding to your version. e.g. https://github.com/jekyll/minima/blob/v2.5.0/README.md
Running bundle show minima will provide you with the local path to your current theme version.

Theme preview

Installation

Add this line to your Jekyll site's Gemfile:

gem "minima"

And then execute:

$ bundle

Contents At-A-Glance

Minima has been scaffolded by the jekyll new-theme command and therefore has all the necessary files and directories to have a new Jekyll site up and running with zero-configuration.

Layouts

Refers to files within the _layouts directory, that define the markup for your theme.

default.html — The base layout that lays the foundation for subsequent layouts. The derived layouts inject their contents into this file at the line that says {{ content }} and are linked to this file via FrontMatter declaration layout: default.
home.html — The layout for your landing-page / home-page / index-page. [More Info.]
page.html — The layout for your documents that contain FrontMatter, but are not posts.
post.html — The layout for your posts.

Home Layout

home.html is a flexible HTML layout for the site's landing-page / home-page / index-page.

Main Heading and Content-injection

From Minima v2.2 onwards, the home layout will inject all content from your index.md / index.html before the Posts heading. This will allow you to include non-posts related content to be published on the landing page under a dedicated heading. We recommended that you title this section with a Heading2 (##).

Usually the site.title itself would suffice as the implicit 'main-title' for a landing-page. But, if your landing-page would like a heading to be explicitly displayed, then simply define a title variable in the document's front matter and it will be rendered with an <h1> tag.

Post Listing

This section is optional from Minima v2.2 onwards.
It will be automatically included only when your site contains one or more valid posts or drafts (if the site is configured to show_drafts).

The title for this section is Posts by default and rendered with an <h2> tag. You can customize this heading by defining a list_title variable in the document's front matter.

Includes

Refers to snippets of code within the _includes directory that can be inserted in multiple layouts (and another include-file as well) within the same theme-gem.

disqus_comments.html — Code to markup disqus comment box.
footer.html — Defines the site's footer section.
google-analytics.html — Inserts Google Analytics module (active only in production environment).
head.html — Code-block that defines the <head></head> in default layout.
custom-head.html — Placeholder to allow users to add more metadata to <head />.
header.html — Defines the site's main header section. By default, pages with a defined title attribute will have links displayed here.
social.html — Renders social-media icons based on the minima:social_links data in the config file.

Sass

Refers to .scss files within the _sass directory that define the theme's styles.

minima/skins/classic.scss — The "classic" skin of the theme. Used by default.
minima/initialize.scss — A component that defines the theme's skin-agnostic variable defaults and sass partials. It imports the following components (in the following order):
- minima/custom-variables.scss — A hook that allows overriding variable defaults and mixins. (Note: Cannot override styles)
- minima/_base.scss — Sass partial for resets and defines base styles for various HTML elements.
- minima/_layout.scss — Sass partial that defines the visual style for various layouts.
- minima/custom-styles.scss — A hook that allows overriding styles defined above. (Note: Cannot override variables)

Refer the skins section for more details.

Assets

Refers to various asset files within the assets directory.

assets/css/style.scss — Imports sass files from within the _sass directory and gets processed into the theme's stylesheet: assets/css/styles.css.
assets/minima-social-icons.svg — A composite SVG file comprised of symbols related to various social-media icons. This file is used as-is without any processing. Refer section on social networks for its usage.

Plugins

Minima comes with jekyll-seo-tag plugin preinstalled to make sure your website gets the most useful meta tags. See usage to know how to set it up.

Usage

Have the following line in your config file:

theme: minima

Customizing templates

To override the default structure and style of minima, simply create the concerned directory at the root of your site, copy the file you wish to customize to that directory, and then edit the file. e.g., to override the _includes/head.html file to specify a custom style path, create an _includes directory, copy _includes/head.html from minima gem folder to <yoursite>/_includes and start editing that file.

The site's default CSS has now moved to a new place within the gem itself, assets/css/style.scss.

In Minima 3.0, if you only need to customize the colors of the theme, refer to the subsequent section on skins. To have your CSS overrides in sync with upstream changes released in future versions, you can collect all your overrides for the Sass variables and mixins inside a sass file placed at _sass/minima/custom-variables.scss and all other overrides inside a sass file placed at path _sass/minima/custom-styles.scss.

You need not maintain entire partial(s) at the site's source just to override a few styles. However, your stylesheet's primary source (assets/css/style.scss) should contain the following:

Front matter dashes at the very beginning (can be empty).
Directive to import a skin.
Directive to import the base styles (automatically loads overrides when available).

Therefore, your assets/css/style.scss should contain the following at minimum:

---
---

@import "minima/skins/{{ site.minima.skin | default: 'classic' }}";
@import "minima/initialize";

Skins

Minima 3.0 supports defining and switching between multiple color-palettes (or skins).

.
├── minima.scss
└── minima
    └── _syntax-highlighting.scss

A skin is a Sass file placed in the directory _sass/minima/skins and it defines the variable defaults related to the "color" aspect of the theme. It also embeds the Sass rules related to syntax-highlighting since that is primarily related to color and has to be adjusted in harmony with the current skin.

The default color palette for Minima is defined within _sass/minima/skins/classic.scss. To switch to another available skin, simply declare it in the site's config file. For example, to activate _sass/minima/skins/dark.scss as the skin, the setting would be:

minima:
  skin: dark

As part of the migration to support skins, some existing Sass variables have been retired and some have been redefined as summarized in the following table:

Minima 2.0	Minima 3.0
`$brand-color`	`$link-base-color`
`$grey-*`	`$brand-*`
`$orange-color`	has been removed

Available skins

classic
dark
solarized
solarized-dark

Customize navigation links

This allows you to set which pages you want to appear in the navigation area and configure order of the links.

For instance, to only link to the about and the portfolio page, add the following to your _config.yml:

header_pages:
  - about.md
  - portfolio.md

Change default date format

You can change the default date format by specifying site.minima.date_format in _config.yml.

# Minima date format
# refer to http://shopify.github.io/liquid/filters/date/ if you want to customize this
minima:
  date_format: "%b %-d, %Y"

Extending the `<head />`

You can add custom metadata to the <head /> of your layouts by creating a file _includes/custom-head.html in your source directory. For example, to add favicons:

Head over to https://realfavicongenerator.net/ to add your own favicons.
Customize default _includes/custom-head.html in your source directory and insert the given code snippet.

Enabling comments (via Disqus)

Optionally, if you have a Disqus account, you can tell Jekyll to use it to show a comments section below each post.

⚠️ url, e.g. https://example.com, must be set in you config file for Disqus to work.

To enable it, after setting the url field, you also need to add the following lines to your Jekyll site:

  disqus:
    shortname: my_disqus_shortname

You can find out more about Disqus' shortnames here.

Comments are enabled by default and will only appear in production, i.e., JEKYLL_ENV=production

If you don't want to display comments for a particular post you can disable them by adding comments: false to that post's YAML Front Matter.

Author Metadata

From Minima-3.0 onwards, site.author is expected to be a mapping of attributes instead of a simple scalar value:

author:
  name: John Smith
  email: "john.smith@foobar.com"

To migrate existing metadata, update your config file and any reference to the object in your layouts and includes as summarized below:

Minima 2.x	Minima 3.0
`site.author`	`site.author.name`
`site.email`	`site.author.email`

Social networks

You can add links to the accounts you have on other sites, with respective icon, by adding one or more of the following options in your config. From Minima-3.0 onwards, the usernames are to be nested under minima.social_links, with the keys being simply the social-network's name:

minima:
  social_links:
    twitter: jekyllrb
    github: jekyll
    stackoverflow: "11111"
    dribbble: jekyll
    facebook: jekyll
    flickr: jekyll
    instagram: jekyll
    linkedin: jekyll
    pinterest: jekyll
    telegram: jekyll
    microdotblog: jekyll
    keybase: jekyll

    mastodon:
     - username: jekyll
       instance: example.com
     - username: jekyll2
       instance: example.com

    gitlab:
     - username: jekyll
       instance: example.com
     - username: jekyll2
       instance: example.com

    youtube: jekyll
    youtube_channel: UC8CXR0-3I70i1tfPg1PAE1g
    youtube_channel_name: CloudCannon

Enabling Google Analytics

To enable Google Analytics, add the following lines to your Jekyll site:

  google_analytics: UA-NNNNNNNN-N

Google Analytics will only appear in production, i.e., JEKYLL_ENV=production

Enabling Excerpts on the Home Page

To display post-excerpts on the Home Page, simply add the following to your _config.yml:

show_excerpts: true
