使用HTML和CSS修复按钮动画

Question

我有一个用HTML和CSS制作的基本按钮，当悬停在它上面时显示一个文本。我想纠正动画效果，这是不太正确的。

移除光标后，动画将大幅减小按钮的大小。因此，也许它可以完成一个过渡效果？

我希望我说得够清楚了！

.home-button {
  line-height: 100%;
  padding: 5px 40px 5px 5px;
  font-family: Arial;
  font-size: 12px;
  position: relative;
}

.home-button span {
  position: absolute;
  top: 20px;
  opacity: 0;
  font-weight: 600;
  color: #454b54;
}

.home-button:hover {
  animation-name: enlarge;
  animation-duration: 1s;
  animation-fill-mode: forwards;
}

.home-button:hover span {
  animation-name: appear;
  animation-duration: 1.5s;
  animation-fill-mode: forwards;
}

.home-button::before {
  margin-right: 5px;
  background-image: url(https://mcusercontent.com/ec104f3d77537e1962ab6441c/images/d7bb4928-a156-4682-9677-d0d5b47c3a21.png);
  background-size: 40px 40px;
  display: inline-block;
  width: 40px;
  height: 40px;
  border-radius: 100%;
  content: "";
}

.home-complement-button {
  background-color: #fff;
  border-radius: 100px;
  box-shadow: 0 4px 8px #dadce0;
  transition: 0.3s;
}

.home-complement-button:focus {
  background-color: #e8f0fb !important;
}

@keyframes appear {
  from {
    opacity: 0;
  }
  to {
    opacity: 1;
  }
}

@keyframes enlarge {
  from {
    padding-right: 40px;
  }
  to {
    padding-right: 50px;
  }
}

<div style="display:flex;user-select:none"><a class="home-button home-complement-button" href="https://esims.one/" style="-webkit-tap-highlight-color:rgba(0,0,0,0);text-decoration:none"><span>Home</span></a></div>

Answer 1

你不需要为此使用动画。只需使用转换即可。这样会更平滑。

​

.home-button {
  line-height: 100%;
  padding: 5px 40px 5px 5px;
  font-family: Arial;
  font-size: 12px;
  position: relative;
  transition: 1s;
}

.home-button span {
  position: absolute;
  top: 20px;
  opacity: 0;
  font-weight: 600;
  color: #454b54;
}

.home-button:hover {
  padding-right: 50px;
}

.home-button:hover span {
  transition: opacity 1.5s; /* I added the transition here because I want it to take 0 seconds when come back. */
  opacity: 1;
}

.home-button::before {
  margin-right: 5px;
  background-image: url(https://mcusercontent.com/ec104f3d77537e1962ab6441c/images/d7bb4928-a156-4682-9677-d0d5b47c3a21.png);
  background-size: 40px 40px;
  display: inline-block;
  width: 40px;
  height: 40px;
  border-radius: 100%;
  content: "";
}

.home-complement-button {
  background-color: #fff;
  border-radius: 100px;
  box-shadow: 0 4px 8px #dadce0;
  transition: 0.3s;
}

.home-complement-button:focus {
  background-color: #e8f0fb !important;
}

<div style="display:flex;user-select:none"><a class="home-button home-complement-button" href="https://esims.one/" style="-webkit-tap-highlight-color:rgba(0,0,0,0);text-decoration:none"><span>Home</span></a></div>

从我自己来说，我可以提供这个解决方案：

​

.home-button {
  line-height: 100%;
  padding: 5px 5px 5px 5px;
  font-family: Arial;
  font-size: 12px;
  position: relative;
  
  display: flex;
  justify-content: space-between;
  align-items: center;
  width: 40px;
  
  transition: 0.3s;
}

.home-button span {
  top: 20px;
  opacity: 0;
  font-weight: 600;
  color: #454b54;
  
  margin: auto;
}

.home-button:hover {
  width: 100px;
}

.home-button:hover span {
  opacity: 1;
  animation-name: text_left;
  animation-duration: 1s;
}

.home-button::before {
  background-image: url(https://mcusercontent.com/ec104f3d77537e1962ab6441c/images/d7bb4928-a156-4682-9677-d0d5b47c3a21.png);
  background-size: 40px 40px;
  display: inline-block;
  min-width: 40px;
  min-height: 40px;
  border-radius: 100%;
  content: "";
}

.home-complement-button {
  background-color: #fff;
  border-radius: 100px;
  box-shadow: 0 4px 8px #dadce0;
}

.home-complement-button:focus {
  background-color: #e8f0fb !important;
}

@keyframes text_left {
  from {
    opacity: 0;
  }
  to {
    opacity: 1;
  }
}

<div style="display:flex;user-select:none"><a class="home-button home-complement-button" href="https://esims.one/" style="-webkit-tap-highlight-color:rgba(0,0,0,0);text-decoration:none"><span>Home</span></a></div>
