Beginning Modern JavaScript Development with Microservices, WebRTC, and React

Overview of this book

JavaScript has now become a universal development language. Whilst offering great benefits, the complexity of the entire ecosystem can be overwhelming. In this course, we will take a look at the libraries in JavaScript that aid in building applications that have a microservices-based architecture, have features like audio and video calling, real-time score updates, multi-faceted search options and more. We will not only look at building these applications but also explore a number of industry-standard best practices. With coverage of both server-side and front-end development, this course will provide attendees with the skills required to develop cutting-edge web applications that stand the test of time. The code bundle for this course is available at https://github.com/PacktPublishing/Beginning-Modern-JavaScript-Development-with-Microservices-WebRTC-and-React

Section 3
Understanding the rem and em CSS Units
This video explains how Bootstrap 4 has switched from pixels (px) to rem and em wherever possible. 1 em is equal to the current font size of the parent element. 2 em means two times the size of the current font. This means that we can achieve responsive typography and components by just changing the parent element's font size using CSS media queries for different viewports or device width sizes. Let us begin by: - Using the new grid system - Using spacing utility classes - Demonstrate the use of display headings - Implement the inverse table feature in a web page
