* The `offset` modifier can shift your popper on both its axis.
|
|
*
|
|
* It accepts the following units:
|
|
* - `px` or unitless, interpreted as pixels
|
|
* - `%` or `%r`, percentage relative to the length of the reference element
|
|
* - `%p`, percentage relative to the length of the popper element
|
|
* - `vw`, CSS viewport width unit
|
|
* - `vh`, CSS viewport height unit
|
|
*
|
|
* For length is intended the main axis relative to the placement of the popper.<br />
|
|
* This means that if the placement is `top` or `bottom`, the length will be the
|
|
* `width`. In case of `left` or `right`, it will be the height.
|
|
*
|
|
* You can provide a single value (as `Number` or `String`), or a pair of values
|
|
* as `String` divided by a comma or one (or more) white spaces.<br />
|
|
* The latter is a deprecated method because it leads to confusion and will be
|
|
* removed in v2.<br />
|
|
* Additionally, it accepts additions and subtractions between different units.
|
|
* Note that multiplications and divisions aren't supported.
|
|
*
|
|
* Valid examples are:
|
|
* ```
|
|
* 10
|
|
* '10%'
|
|
* '10, 10'
|
|
* '10%, 10'
|
|
* '10 + 10%'
|
|
* '10 - 5vh + 3%'
|
|
* '-10px + 5vh, 5px - 6%'
|
|
* ```
|
|
* > **NB**: If you desire to apply offsets to your poppers in a way that may make them overlap
|
|
* > with their reference element, unfortunately, you will have to disable the `flip` modifier.
