Prerequisites

Hugo extended version (for Sass/SCSS support).

For macOS users, the extended version is installed by default if you use homebrew.

For Windows users, you can install with choco:

choco install hugo-extended -confirm

Note that this theme only supports Hugo version 82 and above.

Getting started

At the root of your Hugo project, run:

git submodule add https://github.com/jakewies/hugo-theme-codex.git themes/hugo-theme-codex

Next, copy the contents of the exampleSite/config.toml to your site's config.toml. Make sure to read all the comments, as there a few nuances with Hugo themes that require some changes to that file.

The most important change you will need to make to the config.toml is removing this line:

themesDir = "../../" 

It only exists in the example site so that the demo can function properly.

Finally, run:

hugo server -D 

Note: If you are seeing a blank page it is probably because you have nothing in your content/ directory. Read on to fix that.

Configuring the Home Page

The site's home page can be configured by creating a content/_index.md file. This file can use the following frontmatter:

---
heading: "Hi, I'm Codex"
subheading: "A minimal blog theme for hugo."
handle: "hugo-theme-codex"
---

If you would rather override the about page's layout with your own, you can do so by creating a layouts/index.html. You can find the index.html file that hugo-theme-codex uses here.

Configuring Social Icons

Social Icons are optional. To show any of these icons, just provide the value in the [params] section of config.toml.

# config.toml

[params]
  twitter = "https://twitter.com/GoHugoIO"
  github = "https://github.com/jakewies/hugo-theme-codex"
  # ...

  iconOrder = ["Twitter", "GitHub"]

If any of these options are given, hugo-theme-codex will render the social icon in the footer, using the order specified in iconOrder.

See the contents of the example site for more details.

You can also create additional social icons by:

1. Adding your own SVGs in static/svg/, for example static/svg/reddit.svg.
2. Modifying your site's config as follows:

   [params]
      # ...
      reddit = "<url to your reddit>"
   
      iconOrder = ["Reddit"]

Make sure that the icon title must match the icon's file name. If the title contains more than one word, say "My Awesome Site", you can use dash "-" for the icon name: my-awesome-site.svg.

Creating a blog post

You can create a new blog post page by going to the root of your project and typing:

hugo new blog/:blog-post.md

Where :blog-post.md is the name of the file of your new post.

This will execute the theme's blog archetype to create a new markdown file in contents/blog/:blog-post.md with the following frontmatter:

# Default post frontmatter:

# The title of your post. Default value is generated
# From the markdown filename
title: "{{ replace .TranslationBaseName "-" " " | title }}"
# The date the post was created
date: {{ .Date }}
# The post filename
slug: ""
# Post description used for seo
description: ""
# Post keywords used for seo
keywords: []
# If true, the blog post will not be included in static build
draft: true
# Categorize your post with tags
tags: []
# Uses math typesetting
math: false
# Includes a table of contents on screens >1024px
toc: false

The frontmatter above is the default for a new post, but all values can be changed.

Configuring Table of Contents in blog posts

To display post title in Table of Contents in blog posts, set showPageTitleInTOC to true in the [params] section of config.toml.

# config.toml

[params]
  # ...
  showPageTitleInTOC = true

Adding a new section menu

In your site's config.toml, add a new menu definition for say, "photos":

# config.toml

[[menu.main]]
    identifier = "photos"
    name = "photos"
    title = "Photos"
    url = "/photos"

Then, put your posts under "content/photos".

Custom styling

You have two options for custom styling. The first is to create an assets/scss/custom.scss in your project and put your custom styling there. For example, the snippet below changes the dot's color on your About page to blue:

// custom.scss
.fancy {
  color: #1e88e5;
}

You can even use Hugo variables/params in your custom styles too!

// custom.scss
.fancy {
  color: {{ .Site.Params.colors.fancy | default "#1e88e5" }}
}

# config.toml
[params.colors]
    fancy = "#f06292"

The second option is to use the supported scss overrides. You can do this by creating an assets/scss/overrides/scss file in your project. The following overrides are supported:

// overrides.scss

// The primary accent color used throughout the site
$primary: ''

Tags

Right now hugo-theme-codex uses the tags taxonomy for blog posts. You can view all the blog posts of a given tag by going to /tags/:tag-name, where :tag-name is the name of your tag.

i18n

Support for i18n is currently available for the following languages:

• English
• German

If you would like to have another language supported, create a post in the Discussions section of the repository. You may also support your language of choice by creating a i18n/ directory in your project with a .toml file named after the language you are supporting.

There are not many UI-related strings to override in this theme. If you are looking to support a language of your own, refer to the i18n/en.toml file to see which strings can be overridden.

Favicon

To update favicon of the site, replace the one in static/favicon.ico with your own.
