Hovering over the green links of the feedback section on the community page makes them completely white and unreadable:
https://www.minecraft.net/en-us/community#feedback-section

This is cause by some inline styles setting a white background for the text, which is overwriting the black background intended for hover. As the text color for hover is also set to white, this make the text invisible.

It seems like there already is an extra specific rule with the black background for hover in the feedback section:

#feedback-section .text-generic p a:hover {
    background-color: #000;
}

However it's missing an !important to be able to overwrite the inline style rule:

#feedback-section .text-generic p a:hover {
    background-color: #000 !important;
}
