dev.css is a tiny, simple, classless CSS framework inspired by new.css. It is designed to make any plain HTML file modern and responsive. The minified stylesheet weighs only ~5.5kb. It also has some extra features, such as an optional sidebar and addons.
You can find the website at devcss.devins.page, which contains a demo page.

dev.css is a great choice for:
- A simple blog
- A simple "about me" website
- Collecting your most used links
- Prototyping your raw HTML
dev.css was not meant for very complex websites. Although, if you need something more complex, you could build from/modify this stylesheet for your website. An example of a site that uses dev.css is SkywardMC's wiki.
To use dev.css in your HTML, simply add the following line to the <head> section of your HTML file:
<link
rel="stylesheet"
href="https://cdn.jsdelivr.net/npm/@intergrav/dev.css@4"
/>Another way to install dev.css is to add the npm package to your project through your preferred package manager. This command adds the latest version to your project.
npm add @intergrav/dev.css
# or
pnpm add @intergrav/dev.cssYou can also load a font from intergrav/fonts (or anywhere else) if you'd like a consistent font. Geist and Inter fonts work with dev.css out of the box, other fonts will require a theme to be used. If these fonts are not available, the default system/browser sans-serif and monospace fonts will be used, such as Microsoft's Segoe UI or Apple's San Francisco.
dev.css takes advantage of semantic HTML elements. Here are some guidelines on how to use them for the best results.
It's recommended that you add a header to your page. To add one, place a <header> tag at the top of your <body>. You can use an <h1> tag as your website's title. You can also add a <p> element as an optional short description of the site.
If you want to add a traditional navigation element, you should lay out your <nav> element like this:
<header>
<h1>Website Title</h1>
<p>An optional description of the website.</p>
<nav>
<ul>
<li><a href="https://example.com">Demo</a></li>
<li><a href="https://example.com">GitHub</a></li>
<li><a href="https://example.com">npm</a></li>
<li><a href="https://example.com">jsDelivr</a></li>
</ul>
</nav>
</header>
If you'd like, you could instead use breadcrumb navigation. If you're using the header-oneline addon while doing this, it's recommended to remove all other elements in the header and move <h1> to <main>.
<header>
<nav>
<a href="../..">dev.css</a> / <a href="..">Blog</a> / Making a Website
</nav>
<h1>Making a Website</h1>
<p>Making a basic website with dev.css.</p>
</header>
For your main content, or the actual content of the page, it is heavily recommended that you wrap all of it in a <main> tag. Otherwise, certain features from dev.css may not work properly. It may also benefit search engine optimization. Here's an example:
<main>
<h1>Page 1</h1>
<p>Welcome to my website's first page! This is an example.</p>
</main>Optionally, you can add a sidebar to your page for pretty much anything you'd like. A good usage for this could be, for example, complex navigation on a docs website, where you wouldn't be able to fit it all into the header. The sidebar will sort normally with the rest of the content on smaller screens. To make a sidebar, place an <aside> tag, and then it's also recommended to put an <article> inside if you want a background. You must put it above the <main> content. You can have up to two sidebars per page - the second one will appear on the right side. You can also make a sidebar collapsible by wrapping it's contents in a <details> tag - adding the open attribute will make it open by default. Here's an example:
<aside>
<article>
<details open>
<summary>Sidebar</summary>
<nav>
<ul>
<li><a href="https://example.com">Page 1</a></li>
<li>
<a href="https://example.com">Page 2</a>
<ul>
<li><a href="https://example.com">Page 2.1</a></li>
<li><a href="https://example.com">Page 2.2</a></li>
</ul>
</li>
<li><a href="https://example.com">Page 3</a></li>
<li><a href="https://example.com">Page 4</a></li>
</ul>
</nav>
</details>
</article>
</aside>Optionally, you can add a footer to your page. This could include copyright information, what the website was built with, it's source link, anything really. To make a footer, place a <footer> tag at the bottom of your <body>. It also formats the nav element in the same way that the header does.
In the end, this is what your page structure should look like if you decide to add everything:
<html>
<head>
...
</head>
<body>
<header>...</header>
<aside>...</aside>
<main>...</main>
<footer>...</footer>
</body>
</html>Wrap all body text in <p> tags, unless it's the sole child of another element. Use the <blockquote> tag for quotes. To highlight text, wrap it in the <mark> tag. For code, use <code> for short inline code snippets and wrap that with <pre> for code blocks. Use <kbd> for keyboard input.
To create a link button, wrap the button in an <a> tag. Here's an example:
<a href="https://example.com">
<button>Click me!</button>
</a>The <details> element can be used to create a toggle-able dropdown without using any JavaScript. Here's an example:
<details>
<summary>Click me!</summary>
<p>Lorem ipsum dolor sit amet.</p>

dev.css provides a basic set of styles. Addons are small CSS or JS snippets that can be used to adjust or add functionality to dev.css based on your needs. Here are the built-in addons.
This addon makes the header much more compact on narrow viewports. To use, add the following line after the dev.css import:
<link
rel="stylesheet"
href="https://cdn.jsdelivr.net/npm/@intergrav/dev.css@4/addon/header-oneline.min.css"
/>This addon makes the header sticky, always staying at the top of the screen. Note that this addon is recommended for small headers, as it may affect the usability of your site if the header is large and takes up a lot of space. If using with header-oneline.css, place this after. To use, add the following line after the dev.css import:
<link
rel="stylesheet"
href="https://cdn.jsdelivr.net/npm/@intergrav/dev.css@4/addon/header-sticky.min.css"
/>This addon creates a small "scroll to top" button in the bottom right corner of your website when the user scrolls down. The button uses the default dev.css button style. The button is slightly opaque so that you can see it but it doesn't block the view. To use this addon, add the following line after the dev.css import:
<script
src="https://cdn.jsdelivr.net/npm/@intergrav/dev.css@4/addon/scroll-to-top.min.js"
defer
></script>This addon automatically opens and closes <details> elements inside sidebars at the 82rem breakpoint. This prevents sidebars from looking awkward on wide screens and improves usability on small screens. To use this addon, add the following line after the dev.css import:
<script
src="https://cdn.jsdelivr.net/npm/@intergrav/dev.css@4/addon/responsive-sidebar.min.js"
defer
></script>dev.css supports custom colors and fonts through themes. You can find some pre-made themes in the /theme folder. To use a theme, simply apply it after the dev.css stylesheet. There are night and day themes, a set of Catppuccin themes, and a terminal theme. For example, to apply the terminal theme, add the following line after the dev.css import:
<link
rel="stylesheet"
href="https://cdn.jsdelivr.net/npm/@intergrav/dev.css@4/theme/terminal.user.min.css"
/>If you are creating your own theme, see the boilerplate.user.css file.
The built-in themes can also be installed to your userstyle manager, such as Stylus. That theme will override any website using dev.css. To install one, open the theme's file in your browser.
