Configuration

fddl is designed to be “zero-config” by default, but it offers deep customization via YAML files.

YAML Frontmatter

Every markdown file in contents/ can include a YAML header blocked by ---.

---
title: "My Page"
date: 2024-03-25
layout: post
tags: ["tag1", "tag2"]
---

Template Configuration (template.yml)

The template.yml file in your template directory defines the site’s structure and behavior.

Navigation

The navigation key defines the menu items for your site.

navigation:
  - label: "Home"
    url: "/"
  - label: "About"
    url: "/about.html"

Theme

fddl supports a CSS-variable-based theme system.

theme:
  name: "custom"
  colors:
    primary: "#ff00ff"
    background: "#000080"
    text: "#ffffff"
  typography:
    font_family: "Comic Sans MS, cursive"
    base_font_size: "16px"
