Expert Eleventy Theme Setup and Customization Services
You chose Eleventy (Static site generator - Wikipedia) for its speed and flexibility — and immediately ran into a problem: there are almost no ready-made themes. Unlike Hugo or Jekyll, starters are full-blown projects that are copied entirely. You need to dissect them, understand the logic, and adapt to your tasks. And if your project goes beyond a blog, customization requires manual reworking of templates, data, and styles.
We take on all this work: configure the settings, change layouts, add missing components, and polish the theme to a production-ready state. With 5+ years of experience and 30 completed Eleventy projects, we guarantee a stable and maintainable result. Get a free consultation to discuss your project.
Problems Clients Come With
- Hydration mismatch and phantom errors: when migrating content from WordPress to Eleventy, data often contains extra whitespace or invalid HTML. We process it through filters and custom parsers.
- Complex navigation and multi-page structures: custom taxonomies, pagination, sorting — in Eleventy this is done via collections, but configuring them requires understanding its data flow. We design a system where any page builds in seconds.
- Design system and dark theme: ready-made starters rarely include CSS variables and a theme switcher. We add isolated styles, animations, and responsive layout from scratch.
How We Customize Eleventy: A Real Case
A client — a SaaS product with 50+ documentation pages. The initial starter eleventy-base-blog didn’t support a sidebar menu, multi-level navigation, or full-text search. We:
- Designed a new collection architecture: pages were split into modules, each with its own meta information.
- Added a custom search plugin based on
elasticlunr— the index is generated at build time, search works without external services. - Wrote Nunjucks components: header with dropdown menu, article cards, breadcrumbs, pagination.
- Integrated Tailwind CSS via a custom config — overrode the palette to match the client’s brand.
- Set up RSS, sitemap, and metadata for SEO.
Result: build time dropped from 12 to 3 seconds (4x faster), Core Web Vitals (LCP < 1.5 s) are in the green zone. Cost savings on maintenance — up to 40% ($1,200/year saved on hosting).
Why Order Eleventy Customization from Us?
We don’t just change colors and fonts. We dive into business logic: how content will be created, how users will navigate, how the site should behave on mobile. Eleventy is powerful, but its configuration requires deep knowledge — we’ve already done it across 30 projects.
Comparison: Self-study setup takes 5–14 days, while our team handles a basic version in 2–4 days. Plus, we offer a 1-year warranty — if something breaks after a template update, we fix it for free. Automation saves additional time — up to 30% of the total budget.
| Parameter | Self-learning | With us |

| Time for revisions | 3–10 days | 1–3 days |
| Risk of errors on update | High | Minimal (warranty) |
| Change documentation | None | Full documentation |
How to Customize Eleventy Templates?
The principle is the same as in Hugo: find the required template in the _includes folder and edit it directly. The starter is a copy, not a package, so changes aren’t lost on updates. Typical customization points:
-
eleventy.config.js— adding filters, collections, passthrough copies. -
src/_data/metadata.json— changing the name, description, author. -
src/_includes/layouts/base.njk— HTML structure, meta tags, scripts.
We always document all changes in the project documentation so you can quickly make adjustments later. Get a consultation — we’ll show you how it works on your project.
