The CSS style for links (HTLM <a>) used by help.minecraft.net is not ideal.
The following uses https://help.minecraft.net/hc/en-us/articles/360034736172-Minecraft-Java-Edition-Support-Resources as example.

Difference between normal text and links not clear enough

Normal text uses #333333 as color, links use #018944. When the links are on their own (e.g. in a list) they can easily be seen. However, when they appear within text spotting them is slightly more difficult and depends on the default font size of the browser.

Especially in Microsoft Edge (whose default font appears to be thinner than Firefox one's) spotting links can be difficult:

Nearly no difference between visited link and text

When a link has been visited already (CSS style a:visited) it gets the color #002412 which is way too similar to the normal text color #333333. This makes differentiating visited links from normal text nearly impossible.
