Sometimes web pages display brief warning boxes at the top with "learn more" links. The learn more link in a specific warning box should go to a page specifically about that warning with, in rough order:

1. screenshot of warning box
2. quoted full text of the warning (for searchability / search engine discovery)
3. detailed text answering:
   • how could have the issue occurred?
   • what should the user do to resolve the issue?
   • how can the user avoid the issue in the future?

E.g. the "Learn more ›" link in the yellow warning box in this screenshot:

links to: https://support.twitter.com/articles/82050-i-m-having-trouble-confirming-my-email which:

• Neither has screenshot nor text of warning
• Covers several topics unrelated to the warning
• Does not answer the above questions

And could be improved by linking to a specific page about this particular warning, containing the above points 1-3, and answering all three questions in point 3.
