dasherize() -> string

Replaces every instance of the underscore character ("_") by a dash ("-").

Example

'border_bottom_width'.dasherize();
// -> 'border-bottom-width'

Note

Used in conjunction with String#underscore, String#dasherize converts a DOM style into its CSS equivalent.

'borderBottomWidth'.underscore().dasherize();
// -> 'border-bottom-width'
