I reviewed the error / warnings from Nu Html Checker and W3C CSS Validation. Errors seems to be mostly coming from plugins used, such as Tailwindcss, AOS (Animate on Scroll), Gatsby Images. etc.

I noted several property doesn't exist errors. Though I verified on MDN documentations that those corresponding properties do exist.

How should we proceed? Let me know if you'd like to discuss this.
