当您将鼠标悬停在图像上方时,图像的边框会在稳定之前闪烁一下。有没有办法解决这个问题?

当我将鼠标悬停在图像中间时,如何让文字显示在图像中间?

编辑:这在Chrome中看起来很棒

我不认为使用webkit模糊时完全有可能获得超级干净的过渡。我之前使用它时有很多渲染问题和故障。当在很多元素上使用它时,它也是一种资源匮乏。我建议将缓和更改为线性并仅针对模糊。那应该收紧一点。

img{
    -webkit-transition: -webkit-filter 0.5s linear;
    -moz-transition: -webkit-filter 0.5s linear;
    -o-transition: -webkit-filter 0.5s linear;
    -ms-transition: -webkit-filter 0.5s linear;
    transition: -webkit-filter 0.5s linear;
}

至于文本淡入。您需要添加一个最初为opacity:0;的元素,但在父块被悬停时更改为opacity:1;。初始HTML更改为:

<div class='block'>
  <img src="https://www.nasa.gov/sites/default/files/styles/image_card_4x3_ratio/public/thumbnails/image/leisa_christmas_false_color.png?itok=Jxf0IlS4">
  <span>Hey there</span>
</div>

新的CSS

/* CSS used here will be applied after bootstrap.css */
body {
  background-color: yellow;
}

img {
  -webkit-transition: -webkit-filter 0.5s linear;
  transition: -webkit-filter 0.5s linear;
}

.block {
  position: relative;
  width: 400px;
}
.block img {
  width: 100%;
}
.block span {
  opacity: 0;
  -webkit-transition: all .3s;
  transition: all .3s;
  color: white;
  position: absolute;
  top: 50%;
  -webkit-transform: translateY(-50%);
          transform: translateY(-50%);
  text-align: center;
  left: 0;
  right: 0;
}
.block:hover > span {
  opacity: 1;
}

img:hover {
  -webkit-filter: blur(4px);
}
