The problem actually isn't getComputeStyle but this line: https://github.com/rcbyr/keen-slider/blob/b7aea40a7cb16032a04ad8a2df2b1c846c5a4f7d/src/core/utils.ts#L66 The container property on the slider is actully null: https://github.com/rcbyr/keen-slider/blob/b7aea40a7cb16032a04ad8a2df2b1c846c5a4f7d/src/plugins/web/web.ts#L221

A possible fix is this:
