Bootstrap Validator

The tool analyzes Bootstrap markup for validity and structural health. It accepts a HTML snippet and a Bootstrap version, then evaluates the markup against Bootstrap conventions for grids, forms, components, and spacing. Example checks include ensuring grid rows contain columns that add to 12, form controls have appropriate classes, and required ARIA attributes are present. The analysis is static and does not render pages, but it provides concrete guidance to fix discrepancies before integration.
Conceptually, the tool parses the input HTML into a DOM-like structure, normalizes class names, and cross-checks with the selected Bootstrap version. Checks cover grid usage, form-control coverage, validation state classes, button groups, and accordion/collapse markup. Optional advanced checks include detecting redundant wrappers, over-nested grids, and missing accessibility attributes. Results are reported as a structured report with issue counts, details, and suggested fixes.
Developers, QA engineers, and front-end teams gain early visibility into Bootstrap conformance, reducing debugging time and drift between design and implementation. Unique value comes from version-aware rules, an actionable issue list, and an exportable report suitable for release notes or pull requests. It is designed to integrate into code reviews or CI pipelines and to scale with project-specific conventions.
Use cases include pre-commit checks, CI validation of template code, and vetting third-party components for Bootstrap compatibility. The tool supports local analysis to preserve code privacy and can be extended with custom rule sets for organization-specific conventions.
