for example, Mini Program, an intelligent train ticket, he should have located a blue layer on top of the page to cover the gray and white of the backgroundColor. But I definitely positioned a view at the top of the page and highlighted the section, and set the overflow:visible of the page. Add margin-top to the page and you can see the prominent blue of the view, but the real gray backgroundColor is still tested with the real Apple machine. I would like to ask how to solve this problem.
PS: because the tone below me is grayish white, so the backgroundColor is set to grayish white, with other colors at the top.
