1 Semantic elements

HTML5 introduces new semantic elements that describe the meaning and purpose of different parts of your web page, such as <header>, <nav>, <article>, <section>, <footer>, and more. These elements can help you debug your web page by making your code more readable and organized, as well as improving your SEO and accessibility. For example, you can use the <article> element to wrap each blog post on your web page, and use the <section> element to divide each post into subsections. This way, you can easily identify and modify each post and its content, as well as help screen readers and search engines understand your web page structure.

HTML5 elements and attributes can improve web page and application debugging by providing semantic meaning, validation, and structure to the code. They offer features such as semantic elements, validation and accessibility, multimedia and graphic elements, Web Storage API, new APIs and features, and compatibility and responsiveness. To debug a web page, developers can use browser developer tools such as Chrome DevTools or Firefox Developer Tools to inspect, modify, and test the HTML5 code. These tools can help find and fix errors in the code, set breakpoints, and step through the code.

The semantic elements also improve the ARIA accessibility for vision-impaired site visitors. You can apply the ARIA attributes to standard elements like div/span as well however it's yet in development by Browser maintainers while semantic elements are ARIA supportive out of the box. Of course, you should consider the standard styles which these elements bring up with them before replacing your generic elements with semantic ones

2 Validation and accessibility attributes

HTML5 also introduces new attributes that can help you validate your input fields and enhance your accessibility features, without relying on external libraries or scripts. For example, you can use the type attribute to specify the type of input you expect from the user, such as email, number, date, or url. This way, you can prevent invalid or inappropriate input from being submitted, and display helpful error messages or hints to the user. You can also use the required attribute to mark an input field as mandatory, and the placeholder attribute to show a sample value or instruction in the input field. Additionally, you can use the aria-* attributes to provide additional information or context to screen readers and other assistive technologies, such as aria-label, aria-describedby, or aria-hidden.

3 Multimedia and graphic elements

HTML5 also supports multimedia and graphic elements natively, without requiring any plugins or extensions. For example, you can use the <video> and <audio> elements to embed video and audio files on your web page, and use the controls, autoplay, loop, and muted attributes to customize their behavior and appearance. You can also use the <canvas> and <svg> elements to draw and manipulate graphics on your web page, and use the JavaScript APIs to create animations, games, charts, and more. These elements can help you debug your web page by reducing the dependency on external resources, improving the performance and security of your web page, and allowing you to manipulate and control your multimedia and graphic elements programmatically.

4 New APIs and features

HTML5 also offers new APIs and features that can help you create more interactive and dynamic web pages and applications, as well as store and access data locally or remotely. For example, you can use the Web Storage API to store key-value pairs of data in the browser, either temporarily (sessionStorage) or persistently (localStorage). This way, you can save user preferences, settings, or states across different sessions or tabs, and debug your web page by inspecting or modifying the stored data using the browser's developer tools. You can also use the Geolocation API to get the user's current location, the Offline API to enable your web page to work offline, the Drag and Drop API to enable drag and drop functionality, and many more. These APIs and features can help you debug your web page by providing more functionality and flexibility to your web page, as well as testing and debugging your web page in different scenarios or conditions.

5 Compatibility and responsiveness

HTML5 also aims to make your web page more compatible and responsive across different browsers and devices, by following the principle of progressive enhancement. This means that you can use HTML5 elements and attributes to provide a basic level of functionality and appearance to your web page, and then enhance it with additional features or styles if the browser or device supports them. For example, you can use the <picture> element to provide multiple sources of images for different screen sizes or resolutions, and use the srcset and sizes attributes to specify the optimal image for each case. This way, you can debug your web page by ensuring that your web page displays correctly and efficiently on different browsers and devices, and fallback gracefully if some features are not supported.
