In plain English

Skeleton is a tiny CSS starting kit that helps you build websites that look good on both desktop and mobile screens. The problem it solves is the blank-page problem: when you start a new website project, you have to write a lot of repetitive CSS just to get basic things right, sensible default styles for headings, buttons, forms, and a grid that rearranges itself on small screens. Skeleton handles all of that for you in roughly 400 lines of CSS. It is intentionally minimal. It styles plain HTML elements directly and includes a simple grid system (a way of laying out columns of content) that adapts to different screen sizes automatically. There is nothing to install or compile, you just link the CSS file in your HTML page and start building. The download includes skeleton.css, Normalize CSS (which irons out inconsistencies between different browsers), and a sample index.html to get you started. You would reach for Skeleton when you want to build a simple website or prototype quickly without the weight and complexity of a full framework like Bootstrap. It works well for solo developers, small sites, and quick mockups. The tech stack is plain CSS with no build tools required.

Copy-paste prompts

Prompt 1
I'm using dhg/skeleton CSS. Write me a complete HTML page with a two-column layout using Skeleton's grid, a header, a styled primary button, and a simple contact form.
Prompt 2
I want to customize Skeleton's default styles without editing skeleton.css directly. Show me which CSS selectors to override in my own stylesheet to change the button color and base font family.
Prompt 3
Help me build a minimal portfolio page using only Skeleton CSS and plain HTML, no JavaScript, no build tools, no frameworks, with a nav bar, a project grid, and a footer.
Prompt 4
How do I add Skeleton CSS to an existing HTML project using a CDN link instead of downloading the files, and what other stylesheets do I need to include alongside it?
