Hi,
The homepage looks good on Safari browser now. Thank you for your assistance.
But, I have one more pressing issue to solve. This is regarding the loading speed of my website, which is very very slow right now. It takes 6.1s for the largest element of my website to become visible, measured on GTmetrix. I tried to use Asset Cleanup & WP Fastest Cache plugins to improve the loading speed but the result is still not good. Can you assist me on this issue as well?
