Color change on hover for text links is only working for external links & not for internal links

The color change on hover for text links is only working for external links & not for internal links within my website. Looking for a solution to make it work for both external and internal links. Really appreciate any help on that. Thank you!

I used the following code:

/* Page content link color */
#page p a:hover {
    background-image: linear-gradient(to right,currentColor 100%,currentColor 0) !important;
    color: red;
}

I see it worked here. Can you share link to page where you use external links & internal links? We can check easier.
