What are the best accessibility features for web development?

Integrating ARIA roles and attributes significantly boosts keyboard navigation. Assign roles like role="navigation" for menus and role="button" for interactive elements, making them identifiable to assistive technologies. Use attributes such as aria-expanded to denote the state of dropdowns, enhancing user awareness. Implement aria-live for dynamic content, ensuring updates are conveyed. Document custom keyboard shortcuts, avoiding conflicts with assistive tools. This approach, combined with logical tab orders and clear focus indicators, ensures a web experience accessible to all, adhering closely to inclusive design principles.

To make correct use of Keyboard navigation in Accessibility standards we can follow: 1. Tab Index: Provide the correct tab index to make keyboard navigation easier and linear. Along with this add skip links to make the jump to the main content directly 2. Semantic Markup: It's very crucial to use semantic markup. Using correct HTML elements while implementing pages reduces manual setup for tab index. like using the correct HTML tag for the label will allow screen readers to capture the element correctly.

Responsive web design & development. Following WCAG guidelines on color contrast, typography, and captions. Semantic HTML. Aria-labels.

ALT feature is a key part of an accessible website/ software but also can help in cases with connection problems or if the software loading time takes to long and the image isn't showing. The ALT feature is meant to be an alternative text if for some reason the image can't be shown. To write an effective ALT you need to write every important detail in the image so in case the image can't be shown the user will not miss a piece of important information that will distrapt he's browsing. Since the ALT is written into the code, it can be read by the accessibility tool readers (such as screen readers), and by any other program that has the ability and promotion to read that code, especially all Search Engines.

Adding Alt text is a great way to make your software more user friendly. It improve the chances to getting into SERP (Search Engine Result Page). Always try to write a small keyword alt text to element.

Accessibility mainly deals with making the website usable for each individual. Images are an integral part of any web content. So to make the images more accessible we can add alt text for more information on the image. Alt tag makes it easy for screen readers to capture the image context based on the provided text. It's equally important to add correct text for alt text.

Implement ARIA roles and attributes for alt text by using aria-labelledby and aria-label on elements without native alt support. This practice ensures accessibility for screen reader users, providing clear, concise descriptions for non-text content. Additionally, aria-describedby can offer detailed explanations for complex visuals. Effective alt text should be short yet descriptive, aiding in both accessibility and SEO by making content understandable and searchable. Focus on relevancy and avoid redundancy to enhance user experience and site visibility.

In my experience with frontend development, I've seen different practices followed for frontend implementation. The main thing I found very useful and important is the Semantic Markup. Semantic Markup is not something just for Accessibility, it's very crucial for the SEO of the website. From the Perspective of Accessibility, Semantic Markup helps screen readers correctly identify the structure and make the navigation and interaction more streamlined.

It's paramount to use HTML elements that inherently convey the structure and meaning of web content. Elements like <header>, <footer>, <nav>, <main>, and <article> directly inform both users and search engines about the role and importance of content within a web page. Headings from <h1> to <h6> establish a clear hierarchy, aiding in content organization and navigability, especially for screen reader users. Semantic tags improve accessibility by helping assistive technologies understand the layout and navigate content more efficiently. It also enhance your website's SEO by allowing search engines to better index and rank your content. Adopting semantic markup is a foundational step towards creating accessible and SEO-friendly web content.

Semantic Markup is not something to worry about these days! In the past, you had to obey the rules of this methodology manually but these days your editor plugins and SEO engines check, optimize and even auto-complete your code in this regard. The most important thing these days is writing clean, short, functional, and compatible code because no extension and AI engine can help you code what you want!

Considera también la variabilidad del contraste en diferentes estados y dispositivos. Asegurarte de que tu diseño mantenga un contraste óptimo no solo mejora la accesibilidad para usuarios con discapacidades visuales, sino que también optimiza la experiencia para una audiencia más amplia, brindando claridad visual y legibilidad en diversas condiciones. Aplicar una gama de colores que cumpla con estándares de accesibilidad no solo es una práctica inclusiva, sino que también eleva la calidad general de tu diseño web.

Picking the right color schema for your website is very important. The color schema should always be relaxing to user eyes. To become more user friendly you can also use icons.

By using aria-describedby to link audio and video elements with text descriptions or transcripts, and aria-labels to label media controls, developers make websites more accessible. Aria-live is great for live captions, informing screen readers about new updates instantly, ensuring a smooth experience for users relying on captions. This careful use of ARIA roles and attributes not only meets accessibility standards but also serves a broad audience, making sure all users can access multimedia content, no matter their hearing abilities or surroundings.

I think every website should have responsiveness because most of us use websites/apps into our mobiles. With responsiveness we get to know more about UX and how can we improve our UX.

You should try to adding more visual component to your websites/app like - High quality images/videos - Icons - Illustrations that way your website become more appealing and user friendly.
