css - 转换 Firefox 中的错误？

Question

官方slideout.js demo在 Firefox 中不会抽搐。

1. 打开我的demo on Codepen在 Firefox 中
2. 打开菜单
3. 关闭菜单
4. 看到 主容器 抽动 - 如何修复此错误？

JavaScript:

var slideout = new Slideout({
  'panel': document.getElementById('main'),
  'menu': document.getElementById('menu'),
  'padding': 256,
  'tolerance': 50
});

document.querySelector('.js-slideout-toggle').addEventListener('click', function() {
  slideout.toggle();
});

document.querySelector('.menu').addEventListener('click', function(eve) {
  if (eve.target.nodeName === 'A') { slideout.close(); }
});

/*
slideout.on('beforeopen', function() {  document.querySelector('.fixed').classList.add('fixed-open'); });
slideout.on('beforeclose', function() {  document.querySelector('.fixed').classList.remove('fixed-open'); });
*/

CSS:

.slideout-menu {
    position: fixed;
    left: 0;
    top: 0;
    bottom: 0;
    right: 0;
    z-index: 0;
    width: 256px;
    overflow-y: auto;
    -webkit-overflow-scrolling: touch;
    display: none;
}
.slideout-panel {
    position:relative;
    z-index: 1;
    will-change: transform;
}
.slideout-open{
    overflow: hidden;
}
.slideout-open body{
    overflow: hidden;
}
.slideout-open .slideout-panel {
    overflow: hidden;
}
.slideout-open .slideout-menu {
    display: block;
}

    margin:0;
}

Answer 1

问题似乎与您的 will-change 属性有关，该属性将此警告添加到我的开发者控制台。

Will-change memory consumption is too high. Budget limit is the document surface area multiplied by 3 (186813 px). Occurrences of will-change over the budget will be ignored.

当我将其调整为小于阈值时，它起作用了。否则，它不会。至于修复它，似乎唯一的解决方案是删除 CSS 属性。

.slideout-panel {
    position:relative;
    z-index: 1;
/*  will-change: transform; */
}
