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.

How Testers Can Remain Valuable in Agile Teams

Traditional software testers must step up if they want to remain relevant in the Agile environment. Agile will most probably continue to be the leading form of the software development process in the coming years.

A Complete Guide To CSS Houdini

As a developer, checking the cross browser compatibility of your CSS properties is of utmost importance when building your website. I have often found myself excited to use a CSS feature only to discover that it’s still not supported on all browsers.

Ask any front-end developer about using a CSS feature whose support is still in the experimental phase in most prominent web browsers. ????
