如何使文本从按钮中心增长？

Question

我正在尝试创建一个主页，其中有 6 个按钮，当用户将光标悬停在它们上时，它们会缩小，并且文本会从每个按钮的中心展开。

我设法得到了这个：

body {
  background-color: white;
}

.button-container {
  position: relative;
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
}

.image-button {
  position: relative;
  overflow: hidden;
  width: 10vw;
  height: 10vw;
  background: none;
  border: none;
}

.image-button img {
  width: 100%;
  height: 100%;
  transition: all 0.5s ease;
}

.image-button:hover img {
  transform: scale(0.6); 
}

.button-container span {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  font-size: 8vh;
  transition: font-size 0.3s ease;
  opacity: 0;
  z-index: 1;
  mix-blend-mode: difference;
  color: white;
}

.image-button:hover + span {
  font-size: 32vh;
  opacity: 1;
}

<div class="button-container">
  <button class="image-button">
    <img src="https://images.squarespace-cdn.com/content/v1/55fc0004e4b069a519961e2d/1442590746571-RPGKIXWGOO671REUNMCB/image-asset.gif" alt="Button Image">
  </button>
  <span>text1</span>
  <button class="image-button">

  </button>
  <span>text2</span>
  <button class="image-button">

  <span>text3</span>
</div>

正如您所看到的，它不是很干净，它有点小故障，并且文本从屏幕中心而不是从按钮中心增长。

我应该改变什么？

Answer 1

快速修复方法是将

pointer-events: none

应用于

<span>

，这样按钮的

hover

状态就不会被取消。

您也可以将更高的

z-index

应用于

.button-container

，但这会稍微改变文本的样式，实际上只是删除

mix-blend-mode: difference;

属性给出的效果。

body {
  background-color: white;
}

.button-container {
  position: relative;
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
}

.image-button {
  position: relative;
  overflow: hidden;
  width: 10vw;
  height: 10vw;
  background: none;
  border: none;
}

.image-button img {
  width: 100%;
  height: 100%;
  transition: all 0.5s ease;
}

.image-button:hover img {
  transform: scale(0.6); 
}

.button-container span {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  font-size: 8vh;
  transition: font-size 0.3s ease;
  opacity: 0;
  z-index: 1;
  mix-blend-mode: difference;
  color: white;
  pointer-events: none;
}

.image-button:hover + span {
  font-size: 32vh;
  opacity: 1;
}
