[Make GSAP Slider Responsive]

Im quite new to GSAP and currently working on a project. 

I found this slider here online: 

See the Pen qjbpaa by gvrban (@gvrban) on CodePen

 and modifyed it to fit my needs. 

 

You can find a it on codepen:  (its ripped out of my project and anonymized so don't wonder for the look)

 

Only problem is, if I resize the page, the slider is of and I have to do a reload of the page to get it fitting again. 

I understand that it is cause of the calculated variables (which are off after a resize).

 

Is there an easy way to make it responsive or do I have to recalculate it with a window.resize? 

Thanks in advance.
