悬停时文字移动

Question

我有一个<div>元素，里面有一个<img>元素，中间是文本。悬停<div>时，图像的不透明度发生变化。如果将图像悬停在上方，则文本将向左移动一个像素，然后再次返回。

.mainimage {
  height: 100%;
  width: 100%;
  background: black;
}

.mainimageimg {
  opacity: 0.8;
  width: 100%;
  height: 100%;
  transition: 0.3s;
}

.mainimageimg:hover {
  opacity: 1;
}

.mainimageheading {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  text-align: center;
  color: white;
  user-select: none;
  font-size: 2.35em;
}

<div class="mainimage">
  <img class="mainimageimg" src="https://wallpaper-house.com/data/out/8/wallpaper2you_232687.jpg" draggable="false">
  <h1 class="mainimageheading">Text here</h1>
</div>
