A Complete Guide To CSS Container Queries

In 2007, Steve Jobs launched the first iPhone, which revolutionized the world. But because of that, many businesses dealt with the problem of changing the layout of websites from desktop to mobile by delivering completely different mobile-compatible websites under the subdomain of ‘m’ (e.g., https://m.facebook.com). And we were all trying to figure out how to work in this new world of contending with mobile and desktop screen sizes.

Three Techniques for Improved Communication and Testing

Anyone who has worked in the software industry for a while can tell you stories about projects that were on the verge of failure. Many initiatives fail even before they reach clients, which is especially disheartening when the failure is fully avoidable.

Top 17 Resources To Learn Test Automation

Lack of training is something that creates a major roadblock for a tester. Often, testers working in an organization are all of a sudden forced to learn a new framework or an automation tool whenever a new project demands it. You may be overwhelmed on how to learn test automation, where to start from and how to master test automation for web applications, and mobile applications on a new technology so soon.

Website Testing: A Detailed Guide

Websites and web apps are growing in number day by day, and so are the expectations of people for a pleasant web experience. Even though the World Wide Web (WWW) was invented only in 1989 (32 years back), this technology has revolutionized the world we know back then. The best part is that it has made life easier for us. You no longer have to stand in long queues to pay your bills. You can get that done within a few minutes by visiting their website, web app, or mobile app.
