Start before/after slider at 33% - Beer Slider JS

Hi! I want to start my before and after slider at 33% instead of 50% (with the button not being in the middle). Been searching for a solution, but I can’t find any.

Does anyone have any answers? It’s built using this:

In the existing code, locate this line:

new BeerSlider(beerSlider, { start: beerSlider.dataset.start });

And replace it with:

new BeerSlider(beerSlider, { start: beerSlider.dataset.start || 33 });

cheers

Huge thanks, @Prashant! It works!
