There isn't (to my knowledge) a great way to accomplish this with CSS without repercussions on the UX.
没有（据我所知）使用 CSS 实现这一点而不会对 UX 产生影响的好方法。
While it's Javascript, and not CSS, the best way I've found to do this is the following:
虽然它是 Javascript，而不是 CSS，但我发现做到这一点的最佳方法如下：
// Disable scrolling.
document.ontouchmove = function (e) {
e.preventDefault();
}
// Enable scrolling.
document.ontouchmove = function (e) {
return true;
}
