Theme Configuration

Theme configuration works in a similar fashion to all the other configuration settings in Grav. You can provide settings for a theme configuration file for your theme with the filename <themename>.yaml in the root of your theme folder. These variables can be accessed in your template files.

It is strongly recommended not to actually change the theme's YAML file, but to override the settings in the user/config folder. This will ensure that the theme's original settings remain intact, allowing you to quickly access the changes and/or revert back whenever necessary.

For example, let us consider the Antimatter theme. By default, there is a file called antimatter.yaml in the theme's root folder. The contents of this configuration file look like this:

enabled: true
color: blue

This is a simple file, but it provides you an idea of what you can do with theme configuration settings. Let us provide an override for these settings plus a new one.

So, create a file in the following location: user/config/themes/antimatter.yaml. In this file put the following contents:

color: red
info: Grav is awesome!

Then in your theme, you can add something like this:

<h1 style="color:{{ config.themes.antimatter.color }}">{{ }}</h1>

This should render out as:

Grav is awesome!

The sky is the limit regarding the configuration of your themes. You can use them for whatever you like! :)

Accessing Theme Info

As of Grav 1.1, you can easily access theme configuration and blueprint-related information. To access information via Twig from the blueprints.yaml such as theme name you can simply use:

{{ }}

For a given example blueprints.yaml configuration of:

name: Antimatter
version: 1.7.0
description: "Antimatter is the default theme included with **Grav**"
icon: empire
  name: Team Grav
keywords: antimatter, theme, core, modern, fast, responsive, html5, css3
license: MIT

You can reach any of these items via grav.theme by using the standard dot-sytnax:

Author Email: {{ }}
Theme License: {{ grav.theme.license }}

You can also reach these same values from a Grav plugin with PHP syntax:

$theme_author_email = $this->grav['theme']['author']['email'];
$theme_license = $this->grav['theme']['license'];

Accessing Theme Configuration

As well as the blueprint information, you can also easily access the current theme configuration with:

Theme Color Option: {{ grav.theme.config.color_option }}

And of course, the same thing in PHP is:

$color_option = $this->grav['theme']['config']['color_option'];
