The importance of accessibility can't be overstated. Automated tools like Lighthouse provide a starting point but capture only about 33% of accessibility errors. This article aims to shed light on the limitations of such automated tools, and the benefits of semantic HTML in accessibility. Automated tools, including Lighthouse, are handy to spot some accessibility issues on websites. But, they only scratch the surface, capturing around 33% of potential errors. This number constitutes between 50% and 75% of actual errors on a website. Addressing these issues is a step in the right direction, but it's important to realize that they don't cover all aspects of web accessibility. Automated tools often fail to detect discrepancies in the visual display of an interactive element and its accessible label. For instance, an image within a button labeled as Search but visually displaying the text GO can confuse users relying on speech commands. Such mismatches are beyond the scope of automated tools, emphasizing the need for manual testing and a deeper understanding of web accessibility principles. Similarly, automated tools can't judge the adequacy of empty alt tags for images. While this may be acceptable for decorative images, providing alternative descriptions for images that contain text or important information is crucial for visually impaired users. In the context of web development, using semantic HTML can significantly enhance accessibility. Semantic HTML uses HTML tags that convey the meaning and structure of web content, making it easier for humans and assistive technologies to understand the purpose of different web elements. We'll dive into some examples of semantic HTML and how it can improve web accessibility: By leveraging semantic HTML elements, developers can greatly enhance web content's accessibility and readability. These elements add meaningful structure to the document, allowing browsers, search engines, and assistive technologies to grasp the content's purpose better. This, in turn, improves the user experience for all individuals. Web accessibility is a cornerstone of inclusive web development. It ensures that websites and web applications are usable by all individuals, irrespective of their abilities. Automated tools can offer a starting point but understanding the principles of web accessibility and leveraging semantic HTML can lead to truly inclusive web experiences.
