WYSIWYG Web Builder

This tool enables visual web page creation without coding by translating drag-and-drop composition into production-ready HTML, CSS, and JavaScript. It targets designers, marketing teams, freelancers, and small agencies who need fast MVPs, landing pages, or product sites with predictable output and clean semantics.
Core logic centers on a block-based canvas with a library of responsive components. The engine maps each block to semantic HTML elements, builds CSS via a design system, and exports a portable project bundle. Required features include a layout engine, responsive grid, accessible markup by default, and ZIP export with assets. Optional features cover custom templates, asset optimization, accessibility checks, and RTL support.
Inputs cover project name, selected template, target breakpoints, color palette, typography, and optional custom CSS. Outputs are index.html, styles.css, app.js, assets/, and a manifest describing component usage. Users can preview export results in a sandbox before download and then integrate into their deployment workflow.
Algorithms handle a 12-column grid with breakpoint-driven behavior. The block-to-HTML mapper outputs semantic structure with ARIA attributes where accessibility is enabled. The tool inlines critical CSS, minimizes JavaScript, and references external resources only when necessary. It also provides localization-ready templates and RTL support for multilingual sites.
Error handling validates inputs, detects incompatible blocks, and flags unsupported templates. If an asset fails to load, the exporter uses safe placeholders and reports manifest warnings. It does not perform server-side execution, focusing on static-ready outputs and build-time integration.
