so i used svg.
However, there are two problems that i cannot solve. 1) If i want to scroll up the page, time, plus, arrow have to also scrolled up. So I used scroll.scrollY, but I can’t read scroll.scrollY coordinates. I tried to print scroll.scrollY but 0 is shown. LOL
2) I want to change time, plus, arrow’s color using array’s color data.
If i swipe the main display, i would like to change the arrow's with pageData's color value, but it cannot be done.
I would be much appreciated if you could give me some tips.
