How do you use Terminal CSS in a project?

Updated

Terminal CSS is a minimal CSS framework for terminal-style interfaces. You use it by loading its stylesheet into an HTML page and then writing plain semantic HTML — headings, lists, tables, navigation, and blockquotes are styled automatically without adding component classes. It fits projects where you want a monospace, terminal aesthetic and are willing to build layout yourself, since the framework ships no grid system.

What Terminal CSS gives you

The framework styles standard HTML elements rather than a large set of utility or component classes. Based on the documentation, the covered areas include:

  • Typography — headings from level 1 through level 6, paragraphs, and blockquotes.
  • Lists — unordered, ordered, description lists, and child list items.
  • Tables — including a worked example of Japanese traditional colors with RGB and hex values.
  • Navigation — logo, items, and an active state.
  • A table of contents component — usable as an index for a blog archive. Unlike regular lists, it supports only a single depth level.
  • Themes — the documentation has a Themes section, so the visual style can be varied.

The project describes itself as "a modern and minimal CSS framework for terminal lovers," and the docs include a "Markdown ❤️ Terminal CSS" section, which suggests the styling is designed to look right on content generated from Markdown.

How to use it

The documentation includes a "How to use" section, which is the authoritative source for the exact install and link steps. The general workflow is:

  1. Get the stylesheet. Follow the "How to use" instructions on terminalcss.xyz to obtain the CSS file or link.
  2. Link it in your HTML. Add the stylesheet reference in the <head> of your page so it loads before your content renders.
  3. Write semantic HTML. Use normal elements — <h1>–<h6>, <p>, <ul>, <ol>, <dl>, <table>, <blockquote>, <nav> — and let the framework style them.
  4. Verify. Open the page and check that headings, lists, tables, and navigation pick up the terminal look. If they don't, the stylesheet isn't loading or is being overridden.

Because the framework targets element selectors, you generally don't need to add classes to get the base appearance. That also means your own CSS can conflict with it if you style the same elements.

Layout: you build the grid

Terminal CSS has no built-in grid system. The documentation states this directly and suggests rolling your own with Flexbox or CSS Grid. So a typical page structure is:

  • Terminal CSS handles the look of individual elements.
  • Your own CSS handles columns, spacing, and responsive arrangement.

If you need a ready-made grid, this framework won't provide one — plan to write a small amount of layout CSS or pair it with another approach.

Things to watch for

  • Single-depth TOC. The table of contents component supports only one level, so nested archives need a different structure.
  • Element-level styling. Since styling comes from element selectors, resetting or restyling those elements in your own CSS will change the framework's appearance.
  • Themes. Check the Themes section of the documentation if the default look isn't what you want; it's the place to see what variations exist.
  • AI-assisted documentation. The docs note AI-assisted documentation, so treat details as a starting point and confirm behavior in your own browser.

When it's a good fit

Choose Terminal CSS when you want a terminal or monospace aesthetic, your content is mostly semantic HTML or Markdown output, and you're comfortable handling layout yourself. Look elsewhere if you need a bundled grid system, a large component library, or utility classes for rapid custom layouts.
