What is the problem?

These pages are in the CSS_Background_and_Borders directory, but it seems a misspell of CSS_Backgrounds_and_Borders.

What did you expect to see?

They should be in
/docs/Web/CSS/CSS_Backgrounds_and_Borders/
(which already exists) instead of
/docs/Web/CSS/CSS_Background_and_Borders/
