Creating a Web Accessible Site: Tips and Best Practices

Accessibility (A11y)

Accessibility is a crucial aspect of website development, as it ensures that everyone, including people with disabilities or impairments, can access and use the website's content. To achieve this, website owners and developers should follow the Web Accessibility Initiative (WAI) guidelines, which provide a comprehensive set of principles, guidelines, and success criteria for making websites accessible to all.

The Web Content Accessibility Guidelines (WCAG) are a set of specific rules and recommendations within the WAI framework. These guidelines aim to address the common barriers faced by people with disabilities when using websites, such as visual, auditory, and cognitive impairments. WCAG provides a detailed list of checkpoints that website owners and developers should follow to ensure their website's accessibility.

By adhering to the WCAG guidelines, website owners and developers can create websites that are not only compliant with accessibility standards but are also user-friendly and enjoyable for everyone to use. It is important to note that making a website accessible is not only a legal requirement in some regions but also a moral obligation to ensure that all users can access and benefit from the website's content.

WCAG guidelines

WCAG guidelines are organized into three levels of conformance: A, AA, and AAA. Each level represents a different degree of accessibility, with level A being the most basic and level AAA being the most advanced.

Here is a brief overview of each level of conformance:

1. Level A: The most basic level of conformance, level A guidelines are the most important and should be implemented by all websites. Level A guidelines ensure that the website is accessible to a wide range of users, including those with visual, auditory, and physical disabilities.
2. Level AA: The second level of conformance, level AA guidelines provide more advanced accessibility features than level A. These guidelines focus on providing greater accessibility for people with disabilities and include guidelines for things like captioning, sign language interpretation, and more.
3. Level AAA: The highest level of conformance, level AAA guidelines provide the most advanced accessibility features. These guidelines are the most difficult to implement and are typically reserved for websites that are dedicated to serving people with disabilities.

It's important to note that not all websites will be able to achieve level AAA conformance, as some of the guidelines may be difficult or impossible to implement. However, by following the guidelines for level A and level AA, most websites can ensure that their content is accessible to a wide range of users, including those with disabilities.

HTML

One of the most important factors in creating accessible websites is to use HTML tags properly. HTML is not bad for accessibility if it is used correctly. By writing proper semantics and using appropriate tags such as <header> and <p>, screen readers can interpret the content and describe it to users.

Language

Language used on the website should be clear and free from jargon or slang words. Acronyms should be expanded with the <abbr> tag to ensure that all users can understand them.

Autofocus and tabindex

The use of tabindex and autofocus attributes is crucial for accessibility, especially when it comes to forms. Each form element should be accessible to users by pressing the tab key on the keyboard, and the autofocus attribute can be used to focus on a specific page element.

Images

Images on the website should have appropriate tags such as <alt> text to describe their content. Alternatively, the <figure> tag can be used to wrap the image, and a <figcaption> tag can provide a description of the image.

Website Design

The website design should be clear, with easily distinguishable states of buttons and links. The contrast of colors should be high, and font size should be large enough to be easily read. The layout of the website should be designed properly to indicate the purpose of each semantic element. While animation can be used, it should be subtle and calming, as sharp animation may be distracting or confusing for some users.

ARIA - tags?

ARIA (Accessible Rich Internet Applications) tags are essential in creating accessible websites. Here are some important ARIA tags that should be used:

• role: This tag indicates the role of the current element. It can be used for elements such as search, tab, alert, link, button, and navigation.
• aria-atomic: This tag indicates whether an element's content is static or can be changed without notifying the user.
• aria-autocomplete: This tag indicates whether user input should be completed automatically by the browser.
• aria-busy: This tag indicates whether an element is currently loading or processing.
• aria-checked: This tag indicates the state of a checkbox or radio button.
• aria-controls: This tag identifies an element that controls the behavior or state of another element.
• aria-current: This tag indicates the currently active item in a list or set of items.
• aria-description: This tag provides a description of the element.
• aria-describedby: This tag identifies an element that describes the current element.
• aria-disabled: This tag indicates whether an element is currently disabled or not.
• aria-expanded: This tag indicates whether a collapsible element is currently expanded or collapsed.
• aria-haspopup: This tag indicates whether an element has a popup menu or dialog and provides the ID of the modal.
• aria-hidden: This tag indicates whether an element is currently hidden from the user.
• aria-invalid: This tag indicates whether user input is valid or not.
• aria-keyshortcuts: This tag defines a set of keyboard shortcuts associated with an element.
• aria-label: This tag provides a label for an element that is not visible on the screen.
• aria-labelledby: This tag identifies the element that labels the current element.
• aria-modal: This tag indicates whether an element is a modal dialog.
• aria-multiline: This tag indicates whether a textbox allows multiple lines of text.
• aria-multiselectable: This tag indicates whether multiple options can be selected in a listbox or treeview.
• aria-orientation: This tag indicates the orientation of a slider or scrollbar.
• aria-placeholder: This tag provides a placeholder text for a textbox or textarea.
• aria-readonly: This tag indicates whether a textbox or textarea is read-only or not.
• aria-relevant: This tag indicates the types of changes to an element's content that should be announced to the user.
• aria-required: This tag indicates whether user input is required or not.
• aria-roledescription: This tag provides a description of an element's role for users of assistive technology.
• aria-selected: This tag indicates whether an option in a listbox or treeview is currently selected.
• aria-valuemax: This tag indicates the maximum allowed value for a range widget, such as a slider or progress bar.
• aria-valuemin: This tag indicates the minimum allowed value for a range widget.
• aria-valuenow: This tag indicates the current value of a range widget.
• aria-valuetext: This tag provides a human-readable description of the value of a range widget, which can be read by assistive technologies.

By using these ARIA tags properly, website owners and developers can create accessible websites that are user-friendly for all users, including those who rely on assistive technologies.

Note : By following these guidelines, website owners and developers can create websites that are not only accessible but also user-friendly for everyone. It is important to remember that web accessibility is not only a legal requirement in some areas but also a moral obligation to ensure that all users can access and benefit from the website's content.?

How to Ensure Accessibility?

There are several ways to test the accessibility of a website. Here are a few methods:

1. Automated Testing: You can use automated tools such as WAVE (Web Accessibility Evaluation Tool) or AXE (Accessibility Engine) to scan your website for accessibility issues. These tools will provide you with a detailed report on the accessibility issues found on your website.

1. Manual Testing: You can manually test your website for accessibility by using assistive technologies such as screen readers, magnifiers, and keyboard-only navigation. This will help you identify any issues that automated tools may have missed.
