I'm currently working on a transition from a pure HTML/CSS/JS website to React, and I've run into a big challenge: CSS collisions. I've created a 'calculator' in React that I want to add to the existing site without using an iframe. The old site's CSS has some chaotic styles, including unexpected font colors and sizes that interfere with my new component. I've been using Tailwind CSS for the calculator along with a library called tailwindcss-scoped-preflight to keep styles isolated, but I can't figure out how to prevent the legacy CSS from affecting my calculator. What approaches can I take to solve this?
