我想将particleJS设置为三页单滚动网页的背景。这是JSFIddle。这是particleJS Github页面

我已经注释掉了将particleJS设置为第一页背景的css,因为取消注释该css会使段落在中型和大屏幕中向左对齐。

$('a.page-scroll').on('click', function(event) {
  var $anchor = $(this);
  $('html, body').stop().animate({
    scrollTop: $($anchor.attr('href')).offset().top - 30
  }, 1000);
  event.preventDefault();
});

这里是如何让你的div悬停另一个。我使用该z-index属性将文本放在画布上。
