 Here's how the affix plugin works:
 
-- To start, the plugin adds `.affix-top` to indicate the element is in its top-most position. At this point no CSS positioning is required.
-- Scrolling past the element you want affixed should trigger the actual affixing. This is where `.affix` replaces `.affix-top` and sets `position: fixed;` (provided by Bootstrap's code CSS).
-- If a bottom offset is defined, scrolling past that should replace `.affix` with `.affix-bottom`. Since offsets are optional, setting one requires you to set the appropriate CSS. In this case, add `position: absolute;` when necessary. The plugin uses the data attribute or JavaScript option to determine where to position the element from there.
