I was having problems with resizing my main image, the slider to resize with height when making the browser smaller. Any tips would be welcome. I’ve tried having the image as a percentage. The images scale ok, its the slider outline itself which doesn’t move in height?
The most reliable way of ensuring the slider takes the height of the images, is by actually using images instead of background images. All the images will of course have to be pre-cropped to the same dimensions before uploading, then unset slider & mask’s height styles.
Otherwise, instead of using background-size:contain, use cover instead.
