1 Why context matters

Context is the information that helps users understand the purpose, meaning, and structure of your web page. Without context, users may get confused, frustrated, or miss important details. For example, imagine a web page that has a list of items, but no heading, label, or description to indicate what the list is about. How would you know if the items are products, categories, links, or something else? How would you interact with them? How would you navigate to other sections of the page? Context helps users answer these questions and more.

Context is vital because it gives meaning and clarity to information, facilitates effective communication, influences decision-making, and helps us understand complex situations. It plays a role in everything from problem-solving to cultural sensitivity, historical understanding, legal matters, scientific research, social interactions, memory, and emotional intelligence

2 How to use HTML5 semantic elements

One of the easiest ways to add context to HTML5 is to use semantic elements. Semantic elements are tags that have a specific meaning and role, such as <header>, <nav>, <main>, <article>, <section>, <footer>, and more. These elements help users and assistive technologies identify the different parts of your web page and their functions. For example, using <nav> for your navigation menu tells users that this is where they can find links to other pages. Using <main> for your main content tells users that this is where they can focus their attention. Using semantic elements also helps you create a clear and logical outline of your web page, which improves readability and navigation.

3 How to use HTML5 aria attributes

Another way to add context to HTML5 is to use aria attributes. Aria stands for Accessible Rich Internet Applications, and it is a set of attributes that you can add to your HTML elements to enhance their accessibility. Aria attributes can provide extra information, such as labels, descriptions, roles, states, and properties, that may not be obvious from the HTML alone. For example, using aria-label for a button that has only an icon tells users what the button does. Using aria-describedby for a form input that has a complex validation rule tells users what they need to enter. Using aria-live for a section that updates dynamically tells users when there is new content. Aria attributes can help you fill the gaps and clarify the context of your HTML elements.

HTML5 ARIA (Accessible Rich Internet Applications) attributes enhance web accessibility. Roles, e.g., role="navigation", clarify element functions. Use aria-label for brief names, aria-labelledby to reference an element's ID for labeling, and aria-describedby for additional info. Indicate status with aria-disabled, aria-checked, aria-selected. For live updates, use aria-live, aria-atomic, and aria-relevant. Control tab order with tabindex, set keyboard shortcuts with aria-keyshortcuts. Improve widgets (e.g., sliders, dialogs) for accessibility. Prioritize standard HTML elements, supplement with ARIA when necessary, following ARIA Authoring Practices for web accessibility.

4 How to use HTML5 microdata

A third way to add context to HTML5 is to use microdata. Microdata is a way of adding structured data to your HTML elements, using attributes such as itemscope, itemtype, itemid, itemprop, and itemref. Structured data is a standardized format that describes the content and meaning of your web page, using predefined vocabularies and schemas. For example, using microdata for a product page can tell users and search engines what the product name, price, rating, availability, and description are. Using microdata for a person page can tell users and search engines what the person name, occupation, location, and contact details are. Microdata can help you provide more context and detail about your web page, and also improve your SEO and visibility.

Content Identification: Identify the web content to mark up, like products, events, or reviews. itemscope Attribute: Wrap the content with itemscope to establish its scope. itemtype Attribute: Specify the data type using itemtype, often from vocabularies like Schema.org. itemprop Attributes: Within itemscope, use itemprop to define specific properties and their values. Validation: Use tools like Google's Structured Data Testing Tool to ensure correctness. Implementation: Add the microdata to your webpages for search engines to understand and present richer results. By using microdata, you enhance your content's visibility and search engine understanding, providing more informative search results for users.

5 How to use HTML5 media elements

A fourth way to add context to HTML5 is to use media elements. Media elements are tags that allow you to embed audio, video, and other multimedia content in your web page, such as <audio>, <video>, <picture>, <canvas>, and <svg>. Media elements can enhance your web page with rich and interactive features, but they also need to be accessible to everyone. To add context to media elements, you need to provide alternative text, captions, transcripts, and descriptions that explain what the media content is and how it relates to the rest of the web page. For example, using alt for an image that has important information tells users what the image shows. Using <track> for a video that has dialogue tells users what the speakers are saying. Using <figcaption> for a picture that has a caption tells users what the picture illustrates.

Choose <audio> for audio and <video> for video content. Specify media sources with <source> tags, offering various formats for compatibility. Add controls for user-friendly playback options. Incorporate <track> for captions/subtitles. Use autoplay for auto playback (if needed). Implement responsive sizing with CSS. Enable JavaScript for dynamic control. Thoroughly test on different browsers/devices. Ensure accessibility with alt text and screen reader compatibility.

6 How to test your HTML5 accessibility

The last way to add context to HTML5 is to test your HTML5 accessibility. Testing your HTML5 accessibility means checking if your web page meets the accessibility standards and guidelines, such as the Web Content Accessibility Guidelines (WCAG). Testing your HTML5 accessibility also means checking if your web page works well with different browsers, devices, and assistive technologies, such as screen readers, keyboards, and touch screens. To test your HTML5 accessibility, you can use various tools and methods, such as validators, audits, simulators, feedback, and user testing. For example, using the W3C Markup Validation Service can tell you if your HTML code has any errors or warnings. Using the Chrome Lighthouse Accessibility Audit can tell you if your web page has any accessibility issues or opportunities. Using the NVDA Screen Reader can tell you how your web page sounds to users who rely on speech output. Testing your HTML5 accessibility can help you identify and fix any problems and improve your web page's context and usability.
