ControlsFX Features page -- Borders list item link broken

**[Original report](https://bitbucket.org/controlsfx/controlsfx/issue/594) by Paul Furbacher (Bitbucket: [pfurbacher](https://bitbucket.org/pfurbacher), GitHub: [pfurbacher](https://github.com/pfurbacher)).**

----------------------------------------

On the ControlsFX Features web page (http://fxexperience.com/controlsfx/features/) the "Borders" list item link is broken because of a mismatch between href (origin) and id (target): the "href" is plural, the "id" is singular.

```

Start at the ControlsFX Features web page and inspect the Borders list item and its target anchor, using the HTML shown in the issue. Done means selecting “Borders” navigates to the Borders section without a broken link.
