Wireframe to HTML Skeleton – Quick Layout Boilerplate

CSS Grid is ideal for layout skeletons because it provides precise two-dimensional control over rows and columns. With grid-template-areas, you can define complex layouts (Holy Grail, dashboard, multi-column) using an intuitive ASCII-like syntax. Grid also handles responsive reflow more gracefully than older float or flexbox-only approaches, and modern browser support exceeds 96%.

The Holy Grail layout is a classic web design pattern featuring a header, a footer, and three columns in between—a central main content area flanked by two sidebars (left and right), with all three columns stretching to equal height. Historically difficult to achieve with CSS floats, it's now trivially easy with CSS Grid. It's ideal for content-heavy sites like news portals, documentation hubs, and dashboards.

Absolutely! The generated code is clean, semantic, and follows modern best practices. It uses CSS Grid with fallback-friendly properties. The skeleton is unopinionated about colors and typography, making it an excellent starting point for any project. Simply copy the code, replace the placeholder text with your content, and layer on your design system's styles.

The generated CSS includes a commented-out media query suggestion at the bottom. For multi-column layouts, we recommend adding a breakpoint (typically @media (max-width: 768px)) that collapses sidebars below the main content or stacks all sections into a single column. You can adjust the breakpoint value to match your design system's mobile-first approach.

The Dashboard layout uses height: 100vh to fill the entire viewport with no footer—perfect for admin panels and SaaS apps where the sidebar and main area occupy all available vertical space. The Holy Grail layout includes a footer and typically uses min-height: 100vh, making it scrollable when content overflows. Choose Dashboard for app-like experiences; choose Holy Grail for content websites.

Yes, the generated skeleton code is framework-agnostic but fully compatible with Bootstrap 5. You can drop the generated layout into a Bootstrap project and apply Bootstrap utility classes to the placeholder blocks. The CSS Grid approach doesn't conflict with Bootstrap's flexbox-based grid system—they complement each other at different levels of the layout hierarchy.

Use the slider controls in the Dimensions panel to adjust header height, footer height, sidebar width, content min-height, and gap spacing in real time. The preview updates instantly. Once you're satisfied, the generated code reflects your exact custom values. You can also manually edit the CSS variables or grid-template-rows/grid-template-columns values in the output.
