is it possible to show links on confluence in bold?

[Deleted user]

I would like to know if there is a way to change the configuration of confluence datacenter edition so that when I create a web link it is shown underlined and in bold font.

It is not a one-click thing, but you can edit the CSS style sheet used by Confluence!

See: https://confluence.atlassian.com/doc/styling-confluence-with-css-166528400.html

You should use a selector that selects the "a" elements in the page body.
