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@3">You can also add a font from intergrav/fonts to improve the experience, however it will increase the website download size. 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.
Use the <header> tag to create a large header for your page. Place it at the very top of your <body>. For the title, use an <h1> tag. You can also add an optional <h4> tag before the <h1> tag to provide extra information.
If you need a navigation bar, add a <nav> element with a <ul> that contains <li> items with <a> links. dev.css will automatically lay out the navigation items horizontally, with dividing bullet points between them. If you are using the header-sidebar.css addon, the navigation items will be laid out vertically when in sidebar mode.
Optionally, you can add a <p> tag after the <h1> tag to provide a description of the current page.
Optionally, use the <footer> tag to create a footer for your page. Place it at the bottom of your <body>. You can add any content you like inside the footer.
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 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. To use this addon, add the following line after the dev.css import:
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@intergrav/dev.css@3/addon/header-sticky.min.css">This addon lays everything out in the header horizontally. This is ideal if you don't have much in your header and you want it to be more compact. It works great with header-sticky.css. I do not recommend adding <p> or more than one <nav> element in the header if you're using this. To use this addon, add the following line after the dev.css import:
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@intergrav/dev.css@3/addon/header-oneline.min.css">This addon turns the header into a sidebar on wide displays. The navigation items are listed vertically in this mode. The sidebar will responsively switch back to the default state if the viewport is too narrow to contain everything. If you are using this addon with header-sticky.css or header-oneline.css, make sure to import it after those. To use this addon, add the following line after the dev.css import:
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@intergrav/dev.css@3/addon/header-sidebar.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@3/addon/scroll-to-top.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 themes inspired by terminals, night and day themes, and a set of Catppuccin themes. 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@3/theme/terminal.min.css">If you are creating a custom theme, it is recommended to use the boilerplate-auto.css template for better accessibility.
