I have also had the misfortune of explaining to my PM and designer that the framework they chose heavily limits our ability to colour outside the lines. These kitchen-sink CSS frameworks get you started quickly but it's incredibly difficult to override any one aspect of them. This comes off as a blessing while building out your initial design, but ultimately any team with enough design and development resources is going to want some custom UI/UX elements and what would ordinarily take half a day to build requires an additional week to integrate without side effects. The initial development velocity gives a false sense of progress, as it is followed with death by a thousand cuts. Whenever the tech stack is chosen by a non-developer, the the above scenario inevitably plays out. That's why we offer a stack optimized for ease of onboarding, decreased overall complexity, and reduced technical debt. The clients who use our stack tend to have fewer problems down the line.
