My process

Built with

• Semantic HTML5 markup
• CSS custom properties
• BEM methodology (Block, Element, Modifier)
• Flexbox
• Mobile-first workflow

Useful resources

• BEM Methodology - The idea behind it is to divide the user interface into independent blocks. I really liked this pattern and will use it going forward.
• Semantic HTML - This is an amazing article which helped me finally understand semantic HTML tags. I'd recommend it to anyone still learning this concept.
• Flexbox - This complete guide explains everything about flexbox, focusing on all the different possible properties for the parent element (the flex container) and the child elements (the flex items).
• Schemas.org - A collaborative, community activity with a mission to create, maintain, and promote schemas for structured data.

SEO and Accessibility

Microdata Integration

• Used itemscope and itemtype for the article to define it as a WebSite.
• Mapped itemprop attributes to content elements like headline, description, image, creator, and author for better semantic meaning and SEO.

Accessibility Improvements

• Added aria-labelledby on the article to associate it with the headline, improving screen reader navigation.
• Updated the alt attribute of the image to provide a more descriptive and useful context.

External Links

• Included rel="noopener noreferrer" for all external links to enhance security and performance.

Semantic Structure

• Used a hgroup to group the heading and description semantically.
• Clearly defined elements with roles like footer and main for better screen reader support.

Benefits

• Search Engine Optimization: The microdata ensures search engines can understand the content better, improving its ranking and rich snippets.
• Enhanced Usability: Screen readers can now interpret the purpose and structure of the content more effectively.
• Security and Performance: External links are safer with rel="noopener noreferrer".
