Task guide

Use HTML tools when you need structured head markup, link relationships, or embed code for a page. Start by identifying what you need: preload and prefetch hints for performance-critical resources, link rel tags for SEO and documentation relationships, or responsive iframe embeds for external content. Review the generated output against your page structure before pasting it into your template or CMS. For repeated snippets across many pages, keep a consistent pattern by using the same tool inputs for every post.

Publishing checklist

• Verify generated tags match the HTML5 doctype requirements for your document.
• Check that all attribute values, such as href and src paths, resolve to the correct URLs in your final output.
• Confirm preload and prefetch hints reference actual resources that exist on your server or CDN.
• Test responsive iframe embeds at multiple screen widths, especially the narrowest breakpoint.
• Validate the output against the W3C markup validator before publishing.
