Safari: Best Practices for Compatible Design

Hi everyone, I’m new to no-code and currently building at healiste.com. I’m experiencing noticeable differences in how the page renders across devices, especially in Safari. What are the best practices for ensuring compatibility and consistency in design for Safari browsers? Specifically, are there any particular CSS properties or layout techniques I should avoid or adjust? Any tips on dealing with Flexbox and Grid issues in Safari would be greatly appreciated! Thanks in advance for your advice!
