html - 如何在背景大小更改时屏蔽文本

Question

目前，我正在为我们的网页设计业务开发一个新网站，我需要屏蔽移动导航文本，以便在背景可见时显示它，并在不可见时隐藏文本。
目前动画是这样做的，当背景滑出时文本会重叠。

我基本上需要它来做到这一点 Image of solution (photoshopped)文本被“屏蔽”以在滑出时隐藏。

用蒙版替换背景并保持所有内容相同(大小和位置)

.et_pb_menu__menu {
  position: fixed;
  top: 0;
  left: 0;
  height: 100vh!important;
  width: 100vw;
  background:rgba(254, 209, 7, 0.95);
  -webkit-mask: linear-gradient(135deg, #fff 50.1%, transparent 50%);
  -webkit-mask-size: 100px 100px;
  -webkit-mask-position: -100px -100px;
  -webkit-mask-repeat: no-repeat;
  transition: all 1s ease;
}

.et_pb_menu__menu:hover {
  -webkit-mask-position: 0% 0%;

Clip-path 也可以做到:

.et_pb_menu__menu {
  position: fixed;
  top: 0;
  left: 0;
  height: 100vh!important;
  width: 100vw;
  background:rgba(254, 209, 7, 0.95);
  clip-path:polygon(0 0,0 0,0 0);
  transition: all 1s ease;
}

html:hover .et_pb_menu__menu{
  clip-path:polygon(0 0,200vmax 0,0 200vmax);
}
