Continuous Integration explained with jenkins deployment

Continuous integration is a coding philosophy and set of practices that encourage development teams to make small code changes and check them into a version control repository regularly. Most modern applications necessitate the development of code across multiple platforms and tools, so teams require a consistent mechanism for integrating and validating changes. Continuous integration creates an automated way for developers to build, package, and test their applications. A consistent integration process encourages developers to commit code changes more frequently, resulting in improved collaboration and code quality.

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.

Complete Guide To Styling Forms With CSS Accent Color

The web paradigm has changed considerably over the last few years. Web 2.0, a term coined way back in 1999, was one of the pivotal moments in the history of the Internet. UGC (User Generated Content), ease of use, and interoperability for the end-users were the key pillars of Web 2.0. Consumers who were only consuming content up till now started creating different forms of content (e.g., text, audio, video, etc.).
