Is it possible to make those curves? I've seen people make shapes and clip paths for rigid shapes but haven't found any code for an example with smooth curves like the image above.You can do that with transform (You must be registered for see links)
And clip-path (You must be registered for see links)
How did you create the image? Can you convert it to an SVG? That way you'd accomplish the same as if you were to use CSS, as it would look crisp at any width (which I assume is your goal). You would then just use `background-image` to display it in a `div`.
