The easiest way to install a theme is to clone its repository in the themes
directory:
$ cd themes
$ git clone <theme repository URL>
Cloning the repository using Git or another VCS will allow you to easily update. Alternatively, you can download the files manually and place them in a folder.
You can find a list of themes here.
Now that you have the theme in your themes directory, you need to tell
Zola to use it by setting the theme variable in the
configuration file. The theme
name has to be the name of the directory you cloned the theme in.
For example, if you cloned a theme in themes/simple-blog, the theme name to use
in the configuration file is simple-blog. Also make sure to place the variable in the top level of the
.toml hierarchy and not after a dict like [extra] or [markdown].
Some themes require additional configuration before they can work properly. Be sure to follow the instructions found on your chosen theme's documentation to properly configure the theme.
Any file from the theme can be overridden by creating a file with the same path and name in your templates or static
directory. Here are a few examples of that, assuming that the theme name is simple-blog:
templates/pages/post.html -> replace themes/simple-blog/templates/pages/post.html
templates/macros.html -> replace themes/simple-blog/templates/macros.html
static/js/site.js -> replace themes/simple-blog/static/js/site.js
You can also choose to only override parts of a page if a theme defines some blocks by extending it. If we wanted
to only change a single block from the post.html page in the example above, we could do the following:
{% extends "simple-blog/templates/pages/post.html" %}
{% block some_block %}
Some custom data
{% endblock %}
Most themes will also provide some variables that are meant to be overridden. This happens in the extra section
of the configuration file.
Let's say a theme uses a show_twitter variable and sets it to false by default. If you want to set it to true,
you can update your config.toml like so:
[extra]
show_twitter = true
You can modify files directly in the themes directory but this will make updating the theme harder and live reload
won't work with these files.
