I am putting a slider on a client's site, and want a caption and call-to-action in a 'floating' box to the side, like this:
They were concerned that they will have issues finding proper images with this format (that the image will require a focus in the left 2/3 of the image, and that the aspect ratio might be too wide). We don't want to make the aspect ratio of the slider bigger, so we will likely go with this format:
They like the aspect ratio with this option, but the problem now is that it looks like the caption area is not related to the image at all (especially with other content above and below the slider). What is the best way to indicate that they're related? I've considered a simple triangle/arrow, but there must be a better way of going about it.
