How do I ensure changes work on all browsers?

Question

As a web developer, I'm struggling to create consistent user experiences across different browsers. I've noticed that my website looks great in Chrome but breaks or appears differently in Safari, Firefox, and Edge. I need a comprehensive strategy to test and implement cross-browser compatibility that ensures my designs and functionality remain uniform, regardless of the browser or device. What are the most effective techniques for achieving reliable, universal web experiences?
