Step 2: Semantic HTML5 Blueprinting

2. Semantic HTML5 Blueprinting

Write a clean document structure using strict HTML5 tags to ensure SEO accessibility and readability.

Detailed Implementation Steps:

Create your main index.html in the root directory. Construct the boilerplate layout, referencing your external stylesheet. Ensure you declare the standard UTF-8 charset and layout viewport settings inside the head tags.

Construct your page using semantic HTML5 wrapper tags. Avoid generic divs where tags like <header>, <nav>, <main>, <section>, and <footer> can be used instead. Group the landing page hero panel in a dedicated section with a descriptive ID. Ensure all images and icons feature descriptive alt properties.

Verification Checklist:

1. Inspect your document in the dev tools tree; ensure there are no consecutive non-semantic divs wrapper structures.
2. Run your markup through the official W3C validator to check for unclosed elements.
