How to make a slider with left half image, right half text?

Hi,

I'm trying to make this slider:


Managed text and image on left side, but how do I make the image cover the full left half?

Would be nice if I could have the arrows like this too, but that's less important. Thanks!

You can see what I've done till now here: https://www.toolkitmentorenindezorg.nl/tijdlijn-test/

 

Any idea how I can do this?

 

Hmm, yes exactly what I thought. Will look for another solution in that case
