Download this theme to the themes directory of your Zola website:

$ pwd
/path/to/your/website
$ cd themes
$ git clone https://github.com/IvoWingelaar/forge-theme.git

Select the theme for use by adding the following to the config.toml file:

theme = "forge-theme"

The default templates of this theme use Markdown files with filenames matching *.dnr.md (do-not-render) in the content directory as assets. These should not be rendered by Zola, so you must also add the following to the config.toml file to exclude them:

ignored_content = ["*.dnr.md"]

The menu of the top navigation bar can be customized by setting the extra.menu variable:

[extra]
menu = [
    {url = "/blog/", name = "Blog"},
    {url = "/about/", name = "About"},
    {url = "/contact/", name = "Contact"},
]

The menu has a logo as branding on the left-hand side that can be customized with the following variable:

[extra]
branding_logo_path = "forge.svg"

The hero on the main page contains a logo and some introduction text. These can likewise be customized by setting the following variables:

[extra]
hero_logo = "forge-inv.svg"
hero_content = "hero.dnr.md"

The hero_content will be rendered as Markdown using Zola's markdown filter, and the path must be relative to the site's content directory.

To enable support for mathematical typesetting with KaTeX, add the following to the config.toml file:

[extra]
katex_enable = true

You can then use the katex() shortcode to render KaTeX code in your Markdown files. Marvel upon this majestic proof of a simple algebraic expression:

{% katex(reserve="16em") %} \begin{aligned} (a + b)^2&=(a+b)(a+b) \ &=(a+b)a + (a+b)b \ &=(aa + ba) + (ab + bb)\ &= a^2 + ba + ab + b^2 \ &= a^2 + ab + ab + b^2 \ &= a^2 + 2ab + b^2 \end{aligned} {% end %}

To prevent content layout shift while KaTeX is loading on slower connections, the katex() shortcode allows you to reserve vertical space on your page. This space should not be smaller than the actual required space as the rendered output is centered inside the block reserved by the shortcode and will expand if the reserved space is too small, resulting in the content layout shift we are trying to avoid.

{%/* katex(reserve="16em") */%}
// insert KaTeX code here
// 16 em vertical space will be reserved.
{%/* end */%}

• More customization support.
