You must provide the styles for these classes yourself (independent of this plugin) to handle the actual positions. - -Here's how the affix plugin works: - -- 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 CSS). -- If a bottom offset is defined, scrolling past it 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. - -Follow the above steps to set your CSS for either of the usage options below. - -### Via data attributes - -To easily add affix behavior to any element, just add `data-spy="affix"` to the element you want to spy on. Use offsets to define when to toggle the pinning of an element. - -{% highlight html %} -

For data attributes, append the option name to `data-`, as in `data-offset-top="200"`. - -

offsetnumber | function | object10Pixels to offset from screen when calculating position of scroll. If a single number is provided, the offset will be applied in both top and bottom directions. To provide a unique, bottom and top offset just provide an object offset: { top: 10 } or offset: { top: 10, bottom: 5 }. Use a function when you need to dynamically calculate an offset.
