Hello I am having the same problem I had back in 2015. )Responsive images in sliders)
My images are in a slider and uploaded as background.
Even if I have adjusted the slider size, the images are not responsive…
I tried Try setting the background images to “cover” Make sure the slider has a class assigned to them and set the width of the slider component to width: 100% as suggested years ago, it worked last time but not this time…
