{{ summaryTitle }}

{{ badge.label }}
Use the exact browser-tab title you want in the generated starter.
Keep it concise; the audit table flags descriptions that are blank or very long.
Examples: en, en-US, ms-MY, fr, ja.
This gives the starter page visible content instead of an empty body shell.
Use a project-relative path such as /assets/css/app.css.
Use a project-relative path such as /assets/js/app.js.
Choose Module for modern JavaScript imports, or defer for a classic script file.
Leave blank for reusable local starters; use an absolute https URL for a real page.
Use /favicon.ico, /icon.svg, or another project-relative icon path.
Use a hex color such as #0d6efd, or leave blank to omit it.
The directive is inert until the robots switch below is enabled.
Leave blank when you only need an h1 inside main.
Optional social-preview metadata for starters that already know their canonical URL.
{{ include_open_graph ? 'On' : 'Off' }}
Enable only when the generated page should carry an explicit crawler directive.
{{ include_robots ? 'On' : 'Off' }}
Enable when your starter CSS is ready for light and dark browser form controls.
{{ include_color_scheme ? 'On' : 'Off' }}
Off by default so the boilerplate stays framework-neutral.
{{ include_css_reset ? 'On' : 'Off' }}
Useful for app shells that depend on JavaScript after the first render.
{{ include_noscript ? 'On' : 'Off' }}

HTML boilerplate is the small document frame that lets a browser parse a page predictably before project-specific content and styling take over. A useful starter sets the document mode, language, character encoding, viewport behavior, title, page summary, asset links, and script loading choice without forcing every optional tag into every page.

  

    HTML boilerplate inputs flowing into a starter document and review tabs
  

  
A starter page is often created at the moment when a prototype becomes something that will be opened, shared, or handed to another developer. At that point, an empty document is too thin, while a full template can bring accidental indexing rules, social tags, or asset paths that do not match the project yet.

  
The safest boilerplate is explicit about the basics and conservative about the extras. A generated page can still need project review, especially when canonical URLs, robots directives, theme colors, or share-preview metadata are added before a real deployment path exists.






  
Technical Details:

  
An HTML document begins with a doctype that keeps browsers in standards mode, followed by a root element whose lang attribute tells browsers and assistive technology the primary language of the page. The head then carries metadata that affects parsing, responsive layout, browser tabs, bookmarks, search snippets, icons, and optional sharing surfaces.

  
Character encoding and viewport metadata are foundational because they change how text and layout are interpreted before the body content matters. The generated starter always emits UTF-8 and a responsive viewport. The title is escaped into the document title, while the visible heading falls back to the same value when no separate heading is supplied.

  
Optional head tags should be added only when the values are already meaningful. A canonical URL should point to the preferred absolute address for a real page. Robots directives should not be emitted casually because they can declare indexing intent. Open Graph tags can improve share previews, but this starter emits only type, title, description, and URL fields; it does not add an image tag.

  
Transformation Core:

  

    

      
      
        

          Stage
          Generation Rule
          Result to Check
        

      
      
        

          Document shell
          The output starts with <!doctype html>, a root lang attribute, a head, a body, and a main element containing an h1.
          HTML Starter shows the full starter and the summary reports the generated line count.
        

        

          Required head
          UTF-8, responsive viewport, and title are always included. The meta description is included only when the description field is not blank.
          Head Checklist marks character set, viewport, title, and meta description as included, omitted, or needing review.
        

        

          Asset links
          Stylesheet, script, favicon, canonical URL, theme color, robots, and Open Graph entries are emitted only when their field or switch makes them active.
          Asset Paths lists each optional asset or metadata entry, the tag it becomes, and its head or body placement.
        

        

          Script loading
          A module script becomes <script type="module">. A classic script uses defer so it waits until the document has been parsed.
          The summary line reports module, defer, or no script depending on the script path and loading mode.
        

        

          Warnings
          Blank titles, long or missing descriptions, unusual language tags, non-absolute canonical URLs, missing Open Graph URLs, non-hex theme colors, and whitespace in paths produce notes.
          Boilerplate notes appears when review is needed, and the summary changes from Boilerplate ready to Review starter.
        

      
    

  

  
The generated values are escaped before they are inserted into text nodes or quoted attributes. That makes user-entered titles, descriptions, paths, and URLs safer to copy into a starter document, but it does not prove the values are semantically correct for a project.

  
The JSON output mirrors the generated HTML, head fragment, checklist rows, asset rows, warning list, title, language tag, head element count, optional feature count, and line count. Use it as a review payload when another workflow needs to inspect the same starter choices.






  
Everyday Use & Decision Guide:

  
Begin with Document title, Meta description, Language code, and Main heading. That gives the starter a useful browser title, visible page heading, page summary, and language signal before any project assets are added.

  
Use Stylesheet path and Script path when the project already has stable asset locations. Choose Module script for modern JavaScript imports, or Classic script with defer for a traditional file that should wait for the document to parse.

  
    
    
  • Leave Canonical URL blank for a reusable starter or draft page; add an absolute https URL only when the preferred page address is known.
    • 
    
  • Turn on Open Graph tags only when the title, description, and canonical URL are ready to appear in share previews.
    • 
    
  • Keep Include robots meta off until the page has a deliberate indexing policy.
    • 
    
  • Use Color scheme meta only when the page styling is ready for light and dark form controls.
    • 
    
  • Add the Inline starter reset for a tiny standalone page, but leave it off when the linked stylesheet already owns base styles.
    • 
  

  
Check Boilerplate notes before copying. A clean note count does not mean the page is production-ready; it means the entered values did not trigger the generator's format and completeness warnings.






  
Step-by-Step Guide:

  
    
    
  1. Enter Document title and confirm the summary changes from a fallback title to the intended page name.
    2. 
    
  2. Fill Meta description. If Boilerplate notes reports that it is blank or longer than 160 characters, revise it before using the starter.
    3. 
    
  3. Set Language code with a value such as en, en-US, or ms-MY. If the language warning appears, fix the tag before copying.
    4. 
    
  4. Add Stylesheet path and Script path only when those assets should be linked in the new page.
    5. 
    
  5. Choose Script loading. Review the summary line for module, defer, or no script.
    6. 
    
  6. Open Advanced for canonical URL, favicon, theme color, robots, intro paragraph, Open Graph, color scheme, reset, and no-script options.
    7. 
    
  7. Review Head Checklist and Asset Paths. Fix any Review row or warning before copying from HTML Starter.
    8. 
    
  8. Copy the full starter, copy only the head fragment, or use JSON when the generated details need to be inspected by another process.
    9. 
  






  
Interpreting Results:

  
Boilerplate ready means the current fields produced no generator warnings. Review starter means at least one note should be resolved or accepted before the HTML is copied.

  
The most important review cues are Root language, Meta description, Script tag, and Optional metadata. These rows show whether the starter carries the document signals and asset references you expect.

  
Do not treat a valid-looking HTML starter as proof that linked assets exist, a canonical URL is reachable, or a robots policy is appropriate. Confirm those facts in the project or deployment environment before publishing.






  
Worked Examples:

  
A small project page titled Launch Readiness Dashboard with language en, a concise meta description, /assets/css/app.css, and /assets/js/app.js produces Boilerplate ready. Head Checklist shows the required head items, stylesheet link, and script tag as included.

  
A draft page with no meta description still generates an HTML Starter, but Boilerplate notes reports that no description tag is emitted. Head Checklist marks Meta description as omitted, so the missing summary is visible before the starter is copied.

  
A share-ready page with Open Graph tags enabled but no Canonical URL triggers a warning that the Open Graph URL is omitted. Add the absolute page URL, then check Asset Paths for og:type/title/description/url before using the output.






  
FAQ:

  

    Why did the generated page use Untitled Page?
    
The Document title field was blank, so the starter uses Untitled Page as a fallback and shows a warning.

  

  

    Should I choose module or defer?
    
Choose Module script for modern import-based JavaScript. Choose Classic script with defer when the script is a traditional file that should run after parsing.

  

  

    Why is the canonical URL warning shown?
    
The canonical field has a value that does not look like an absolute http or https URL. Leave it blank for drafts or replace it with the preferred page address.

  

  

    Does this add a share image tag?
    
No. The Open Graph switch emits type, title, description when available, and URL when the canonical field is filled; it does not emit an image field.

  

  

    Does the generator upload my page content?
    
The fields are assembled into the visible starter, checklist, asset table, and JSON output in the browser workflow. There is no upload field or server validation step for the generated page content.
