Over time, development has gotten more complex in some ways, and less in others. As technology develops, some of the requirements for coding that had been necessary in the past has shifted to a need to understand tooling. While changing some parts of a website have become easy due to advancements in CSS tools and other helpers, those changes may be harder to deploy due to build processes. Instead of making a quick and simple change, you may need a full CI/CD process – trading speed for stability and repeatability.
