Web accessibility a fundamental principle of web design which ensures that users can access and interact on web pages regardless of their capabilities. It is essential to focus on accessibility on the web when designing web pages or creating applications.

Proper HTML markup is vital to making sure that your website is accessible. For example using logic-based headers will help viewers to discern the page’s structure. It is advised to also use the appropriate link description and to provide sufficient color contrast.

WCAG Guidelines

The Web Content Accessibility Guidelines (WCAG) are standards for web accessibility for development of applications. These standards are utilized by front-end developers, QA testers, and other web team to ensure that websites meet the minimal accessibility requirements on websites. WCAG includes thirteen guidelines arranged under four main principles: accessible, observable, comprehendable and durable, referred to by the acronym POUR. Each guideline has testable success criteria that make it possible to determine the level of compliance.

Unilever, an international company that makes 400 products sold in more than 2 billion homes worldwide and maintains a web site which is a balance of web accessibility and aesthetically pleasing design. Its site is compliant with WCAG guidelines for colour and contrast in keyboard navigation as well as head structure.

The most notable feature on its website is the presence of visual indicators which indicate which elements on the page have keyboard focus. This makes it simpler for people to read and navigate the text of a webpage without a mouse, along with screen readers or other text-tospeech programmers. This approach is also recommended for websites that have solely keyboard navigation.

Semantic HTML

Additionally, it keeps the style and content separate semantic HTML can make your website easier for assistive technologies to understand. When a browser process a well-written, semantic HTML, the data that it provides is then passed on to assistive devices like screen readers that interpret as well as converted into formats users need.

Additionally to that, using landmarks — which are a group of HTML tags that mark parts of your webpage helps ensure that key areas are keyboard accessible for screen reader and text-to-speech users. Also, be sure to add short explanations of pictures (also called alt attributes) for those who cannot see or comprehend visual images.

Keyboard Friendly Web Interfaces

Certain people browse the web using an electronic keyboard, not an actual mouse. They can be expert “power” keyboard users, or have motor impairments which prevent them from performing the exact motor movements required to operate the mouse. The key is to make interactivity and navigational features easily available through the use of tabbing, and display visually a sign that indicates the focus of your keyboard.

As an example, if you’re using input fields to input of text, forms or drop-down menus make sure that they can be tabbed to and also give a clear indicator of their present state web application development service. Screen readers and other screen magnification tools employ the focus indicator for determining which object is in use.

It is essential that all text that appears on a web page should be clearly accessible and easily read. This is an important aspect of internet accessibility, especially for customers with vision or hearing issues or who have blindness and use assistive technology to navigate your site.

Color Contrast

Utilizing color with enough contrast ensures that all users even those who suffer from color blindness, are able to read and navigate through web-based content. Many people affected by dyslexia get benefit of high-contrast text too.

Roles and Properties for the ARIA explain the status of widgets for assistive technology, like screen users. For example”search,” the role “search” is used to mark a field in a form to indicate an search feature. Roles are constant and never alter when a widget is updated, while properties are dynamic and update when a user interacts with the widget.
