I have a problem with the slide-in's closing X button. It is an svg icon and it is very hard to "touch" it. Only the lines of the X is clickable. It is not that bad on desktop, but it is really hard to click it on mobile.
So please fix it somehow. My suggestion is, that it needs a wrapper, that will have a transparent padding and the click function should trigger that wrapper, not the X itself. So it would be easy to click (touch) it.
You can see my slide-in here:
I made the X icon bigger, but it is still hard to click it.
