Poor Store CSS (Poor visual stability)

[WEALTH1]

Hello great minds, please I need an urgent solution to a Shopify store I am working on, I don't know much about coding or HTML and I discovered that there is a low visual stability of (0.35) on it. I really don't know how to get it improved because the direction I got was to follow CSS Path generator of which requires html to be copy and paste in the theme liquid. I would be very grateful if I can get this resolved🙏🙏 from technical expert.

Thanks in anticipation.
