We’ll have the presentation An Approach to Real-Time, Client-Side Accessibility Audits at CSUN 2023 Conference Friday, March 17, 2023 – 3:20 PM PST.

Description

SiteLint is Google Analytics for Accessibility. The platform allows users to monitor and audit unlimited sites, in real-time, without crawling or auditing in specific time intervals. Users can collect results from real users, networks, and devices, which will improve significantly the remediation process by knowing which pages reported the most issues. This session will provide a demo of SiteLint and talk about the technical challenges overcome.

We had the honor to present SiteLint at A11yTalks in March 2023 – the next generation of automated testing. The speaker (Cezary Tomczyk), the Founder of SiteLint, was talking about recalibrating the remediation process significantly, improving accessibility quality testing, and focusing on user behavior. We were discussing new technology and its unique approach that goes beyond crawling and analyzing data on the server side.

There are several HTML elements that can be used to view Portable Document Format (PDF) files in HTML. The <embed>, <object> and <iframe> elements can all display a PDF file within the web page. Each works in a very similar way, but which one to choose? Let’s find out.

To make a video recording of the entire screen or just a selected portion of it we use QuickTime player. However, recording audio from VoiceOver doesn’t work out of the box. Let’s see then how to achieve that.

Reducing memory and CPU consumption by the Google Chrome browser has always been a challenge. Especially when you have a lot of tabs open. However, with the latest release the browser got 2 features: Memory Saver and Energy Saver.

Your code for the image looks correct. Everything is defined in the srcset and sizes attributes, but the browser downloads a completely different image than the one you expect. Let’s check why this is happening.

Contact Form 7 is a great WordPress plugin that allows you to manage multiple contact forms, plus you can customize the form and the mail contents flexibly with simple markup. However, on the other hand, it is also a potential place to send spam. Similarly, you can send spam using the comment form. To help with blocking, we have created WordPress plugin called Spam Prevention for Contact Form 7 and Comments that do not require any maintenance. Find out more in the next part of the post.

Sometimes the database might work slowly and one of the reasons is a large log file. Tracking database activity is crucial for performance and issues monitoring. However, the log file may grow and therefore may cause the performance issue because of more and more writing and reading on a larger and larger log file. We may avoid such problems by scheduling regular log rotation and keeping the log file size below a defined threshold. Let’s get started on figuring out how to address this issue.

Web performance is all about making websites fast: loading, rendering, and interacting. When pages load slowly or have a lot of content to load then the experience can be very clunky and unpleasant for all users. More resources to download mean also more data that needs to be transferred through the network and processed. Let’s explore user and business impact and how this could be improved.

If you add text over a background image, make sure there is enough contrast to make it readable. Subtle changes may be made to boost contrast without changing the overall aesthetic of the site.

The Web Content Accessibility Guidelines (WCAG) is an internationally recognized standard created by the World Wide Web Consortium (W3C), and WCAG calculates it as a ratio describing the relative luminance of the text and background.

Let’s then see 3 tips to make text over image more readable.
