Building accessible web pages is crucial for making your content available to everyone. This means including alternative text for images, so screen readers can describe them to visually impaired users.

Using semantic HTML elements like header, nav, and main can help search engines and screen readers understand the structure of your page. This is especially important for users who rely on assistive technologies.

A good rule of thumb is to use descriptive alt text for images, such as "A photo of a sunny beach" instead of just "image1". This helps users with visual impairments understand what the image is about.

HTML 2 Structure

The HTML 2 specification defined a basic structure for HTML documents, including a DOCTYPE declaration, an HTML tag, and a body tag.

The DOCTYPE declaration was used to indicate the document type, which in this case was HTML 2.0. This declaration was required for the document to be parsed correctly by web browsers.

The HTML tag was the root element of the HTML document, and it contained all the other elements. It was used to define the document type and version.

The body tag contained the content of the HTML document, including text, images, and other media. It was used to define the main content of the page.

Development

Development is where the magic happens. HTML 2 Structure provides a solid foundation for building web pages, but development takes it to the next level.

The development process begins with writing clean, semantic HTML that is easy to read and understand. This is crucial for search engines to crawl and index your content effectively.

A well-structured HTML document is essential for a smooth development process. This is because it allows developers to focus on adding functionality and content to the site.

The HTML 2 Structure provides a clear and concise way to organize content, making it easier for developers to work with. This is especially important for large and complex websites.

Developers can use the HTML 2 Structure to create a clear hierarchy of content, making it easier to maintain and update the site. This is a huge time-saver in the long run.

A clean and organized HTML document also makes it easier for developers to identify and fix errors. This is because they can quickly locate the source of the problem and make the necessary changes.

By following the HTML 2 Structure, developers can create a solid foundation for their website that is easy to build upon. This sets the stage for a successful development process.

Attributes

Attributes play a crucial role in HTML, and understanding them is essential to building robust and effective web pages. They are name-value pairs, separated by = and written within the start tag of an element after the element's name.

Some attributes can be left unquoted in HTML, but this is considered unsafe. In contrast, certain attributes like ismap for the img element affect the element simply by their presence in the start tag.

The abbreviation element, abbr, is a great example of how attributes can be used. It can demonstrate some of the common attributes that may appear in many elements.

The dir attribute is used to specify text direction, such as with "rtl" for right-to-left text in languages like Arabic, Persian, or Hebrew.

The language-related attribute dir is a must-know for any web developer. It's used to specify the direction of text, which is essential for languages that read from right to left.

Here are some common attributes that may appear in many elements:

  • dir: specifies text direction
  • ismap: affects the img element

The meta tag in HTML has its own set of attributes. The name attribute defines the name of the metadata, and the content attribute is used in conjunction with the name attribute to specify the value of the metadata.

Accessibility in HTML 2

Accessibility in HTML 2 is crucial for ensuring that your website is usable by everyone. Images, image buttons, and image map hot spots should have alternative text that accurately describes the content.

You should also make sure that images that don't convey any content, like decorative images, have empty alternative text (alt=""). This helps screen readers and other assistive technologies navigate your site.

Form buttons should have a descriptive value, and inputs should have associated accessible names. This is especially important for users who rely on screen readers to interact with your site.

Non-Text Content

Non-text Content is a crucial aspect of Accessibility in HTML 2. Images, image buttons, and image map hot spots must have appropriate, equivalent alternative text.

This ensures that users who rely on screen readers can understand the content of these images. For example, an image of a logo should have alternative text that describes the logo, such as "Company Logo".

Images that don't convey content, are decorative, or contain content already conveyed in text should be given empty alternative text (alt="") or implemented as CSS backgrounds. This is because these images don't provide any additional information to users who rely on screen readers.

Complex images, on the other hand, require equivalent alternatives to be provided in context or on a separate linked page. This could be a detailed description of the image, or a separate page with more information.

Form buttons should have a descriptive value, making it clear what action will be taken when the button is clicked. Inputs should also have associated accessible names, so users know what information is being requested.

Embedded multimedia, such as videos or audio files, should be identified via accessible text. This could be a transcript of the video, or a brief description of the audio.

Frames and iframes should be appropriately titled, making it clear what content is being displayed within the frame or iframe.

Here's a quick summary of the key points:

  • Images, image buttons, and image map hot spots must have alternative text.
  • Decorative images should have empty alternative text (alt="") or be implemented as CSS backgrounds.
  • Complex images require equivalent alternatives.
  • Form buttons should have descriptive values.
  • Inputs should have associated accessible names.
  • Embedded multimedia should be identified via accessible text.
  • Frames and iframes should be titled.

Focus Order

Focus Order is a crucial aspect of accessibility in HTML 2. The navigation order of links, form controls, etc. is logical and intuitive.

In order to achieve a logical and intuitive navigation order, it's essential to ensure that the focus order of interactive elements is correct. This means that the order in which users can navigate through a web page using their keyboard should make sense.

A good example of a logical focus order is a navigation menu where the focus moves from one link to the next in a linear fashion. This allows users to easily navigate through the menu using their keyboard.

To achieve a logical focus order, you should ensure that the HTML structure of your web page is clear and consistent. This includes using semantic HTML elements, such as nav and main, to define the structure of your page.

Here are some best practices for implementing a logical focus order:

  • Use a clear and consistent HTML structure.
  • Use semantic HTML elements, such as nav and main.
  • Ensure that the focus order of interactive elements is logical and intuitive.

HTML 2 Best Practices

Use semantic HTML elements to structure your content, as seen in HTML 2's emphasis on using header tags (h1-h6) to define headings and sections.

Always use a doctype declaration at the beginning of your HTML document, just like in HTML 2's example, to ensure compatibility with different browsers and devices.

Use a consistent naming convention for your classes and IDs to make your code more readable and maintainable.

Error Identification

Error Identification is crucial for a good user experience. It helps users understand what's wrong with their input and how to fix it.

To provide clear error identification, required inputs or inputs that require a specific format, value, or length should provide this information within the element's label. This makes it easier for users to understand what's expected of them.

Form validation errors should be efficient, intuitive, and accessible. This means the error should be clearly identified, and users should have quick access to the problematic element. They should also be able to easily fix the error and resubmit the form.

Here's a quick checklist to help you get it right:

  • Provide error information within the element's label.
  • Ensure form validation errors are efficient, intuitive, and accessible.

By following these best practices, you can create a better user experience and make your website more user-friendly.

Bypass Blocks

Bypass Blocks are an essential feature to consider when building accessible web pages. A "skip" link is recommended in addition to headings and regions, as keyboard navigation by headings or regions is not supported in most browsers.

A link is provided to skip navigation and other page elements that are repeated across web pages. This link is typically placed at the top of the page.

Proper use of headings or regions/landmarks is sufficient to meet the success criterion for Bypass Blocks. However, WebAIM recommends a "skip" link as an added measure for accessibility.

Here are some key points to keep in mind when implementing Bypass Blocks:

  • A link is provided to skip navigation and other page elements that are repeated across web pages.
  • A "skip" link is recommended in addition to headings and regions.

Link Purpose is crucial for users to understand where a link will take them. It can be determined from the link text alone, or from the link text and its context, such as surrounding text, list items, previous headings, or table headers.

For instance, if you have a list of links with the same text, it's essential that they go to different locations. This way, users can quickly tell which link will take them where.

A good rule of thumb is to ensure that links with the same text are readily distinguishable. This can be achieved by providing unique link text or adding context to each link.

To make it easier for users to navigate, consider the following:

  • The purpose of each link can be determined from the link text and its context.
  • Links with the same text should go to different locations.

HTML 2 Transition

The HTML 2 transition was a significant shift in the web development world. On May 28, 2019, the W3C announced that the WHATWG would be the sole publisher of the HTML and DOM standards.

The W3C and WHATWG had been publishing competing standards since 2012, which led to a divergence in the standards over time. This divergence started in 2007 when the standards were identical, but different design decisions caused them to diverge.

The WHATWG "Living Standard" had been the de facto web standard for some time, and it's likely that many developers had already adopted it in their work.
