When building accessible web applications, developers have long relied on ARIA and role attributes to fill gaps in native HTML.
But today, many of those gaps are gone. Modern browsers support a wide range of semantic HTML elements and built-in behaviors that make ARIA redundant in most cases, often with better results and fewer bugs.
This shift towards native accessibility features means that developers can now create accessible web applications using built-in browser elements and attributes, rather than relying solely on ARIA and ROLE only.
We’ll explore the native built-in browser elements and attributes that you can use today to improve accessibility, and how they can replace or complement ARIA and ROLE attributes in your web development workflow. By leveraging these native features, you can simplify your code, improve maintainability, and create more accessible web applications for everyone.
XPath, or XML Path Language, is a query language designed to navigate through elements and attributes in an XML document. The document.evaluate() method in JavaScript allows developers to execute XPath expressions against an XML document, returning nodes or values based on the specified query. While this functionality is powerful, it also poses risks of injection attacks if user input is not properly handled.
CSS filter: blur() is a fantastic tool for adding visual interest and depth to your web designs. It creates a soft, out-of-focus effect that can be used in various ways, from creating frosted glass backgrounds to subtle focus indicators. However, by default, the blur effect can sometimes overflow the boundaries of the element it’s applied to, leading to unexpected visual results. This article will guide you through techniques to keep that blur effect neatly contained within its intended space.
Automated accessibility testing tools have gained traction due to their ability to quickly analyze web pages for compliance with accessibility standards, such as the Web Content Accessibility Guidelines (WCAG). These tools can scan a website’s code and identify potential issues, making them an attractive option for developers and organizations looking to improve accessibility.
When working with Angular, formatting currency is quite a common requirement. The Intl.NumberFormat API provides a robust solution for this task, enabling developers to present numbers in a way that is sensitive to the user’s locale.
Semantic HTML. The term itself might sound technical and niche, but its impact on the web is anything but. It’s the foundation upon which accessible, maintainable, and search engine-friendly website content is built. Let’s dive into the core principles of semantic HTML, exploring its benefits, common pitfalls, and ultimately, why it’s a crucial skill for any web developer.
To wait for an HTML element to exist in the DOM using JavaScript, we’ll use requestAnimationFrame to periodically check for the element’s existence, and combine it with Promise to achieve this without blocking the main thread.
This approach is performance-friendly because requestAnimationFrame allows the browser to optimize rendering and ensures that the checks occur at the right time in the rendering cycle.
Website performance, SEO, and accessibility are crucial for online success. A comprehensive audit serves as a critical tool for identifying areas of improvement, enhancing user experience, and optimizing search engine performance. But conducting a thorough audit can seem daunting, especially for smaller businesses or individuals with limited budgets. Thankfully, a plethora of free Chrome extensions offer a convenient and accessible way to analyze your website and identify areas for improvement.
This review explores the capabilities and limitations of using such extensions for website auditing.
To escape HTML string tags in JavaScript, you need to replace certain special characters with their corresponding HTML entities. This is crucial for preventing issues like Cross-Site Scripting (XSS) attacks and ensuring that user-generated content is displayed correctly without being interpreted as HTML.
When embedding content using iframe (inline frame), users may experience delays while the iframe loads, especially if the content is from a slow server or a third-party site. During this period, users may perceive the application as unresponsive. To mitigate this issue, a Please wait message or an animated loading indicator can be displayed, depending on the design requirements.
