CSS With Feature Detection For Cross Browser Compatibility

The primary goal of every web developer is to build websites with modern and intuitive designs that deliver a smooth and seamless user experience irrespective of which browser they might be using to surf the web. The Internet has witnessed a massive unprecedented boom in recent decades. As of Dec 2018, there are more than 4.1 billion internet users in the world and close to 1.94 billion websites on the web. This consequently implies an expansion in a number of ways websites are being accessed by audiences across the globe. This gives rise to the conundrum of cross browser compatibility which poses a huge challenge to developers. As the number of browsers and their versions are growing at such a rapid pace every year, the task of trying to make a website appear and perform consistently across all browsers is every developer’s nightmare. However, as tedious and time-consuming as cross browser testing may be, it is an imperative phase of every testing cycle. While it is considered nearly impossible to have a website appear and work identical on every browser, there still are a number of ways to deliver consistent user experience and reach a wider target audience. In this article, we’ll explore what cross browser compatibility issues are and why do they occur, how cross browser CSS with feature detection is more favorable to browser detection.

Cypress End to End Testing Tutorial: A Detailed Guide

Software applications nowadays have become increasingly complex, and maximizing test coverage is one of the key aspects for every testing team. Testers globally rely upon different testing types using testing tools and frameworks. But there is an urgent need to test software systems (along with all their sub-systems) from beginning to end.

Complete Guide To WordPress Testing

If you are a web developer, website owner, or associated with the web world, you must have come across the term WordPress. I have heard “WordPress” probably more than “Django or Ruby on Rails.” Later, I found out that this is not just random luck. WordPress will be used by 43.2 percent of all websites on the internet in 2022. This represents an increase from the previous year by 39.5 percent. That means WordPress is used by two out of every five websites. There are too many reasons for this success, and I will dictate each one with the relevant sections.
