CSS Img仅在悬停时调整过渡时间

标签： html css html5 css3 image-resizing

我对其中一张图片的动画存在问题。我希望图像在悬停时具有过渡时间调整大小（然后在鼠标移开图像时将过渡时间恢复为原始大小），但是当我调整窗口大小并相应调整图像大小时，它会随着过渡而调整大小时间 。有人知道解决这个问题的方法吗？

<div class="column">
    <a href="-----.html">
        <img src="-----.jpg">
    </a>
</div>

.column img{
    filter: brightness(0.8);
    transition: 0.6s ease;
    width:100%;
    height: calc(100vh - 300px);
}

.column:hover img{
    filter: brightness(0.5);
    width:110%;
    transform: translate(-5%,-5%);
    transition: 0.6s ease;
    height: calc(110vh - 300px);
}

我可以看到为什么在调整窗口大小时将过渡应用于图像，但是我不知道当鼠标移开时如何再应用过渡。有人可以建议解决这个问题的方法吗？

您需要为width分配hover而不是.column img{ filter: brightness(0.8); transition: 0.6s ease; width:35%; } .column:hover img{ filter: brightness(0.5); width:110%; transform: translate(-5%,-5%); transition: 0.6s ease; }进行动画，然后选中

<div class="column">
    <a href="-----.html">
        <img src="https://www.google.co.in/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png">
    </a>
</div>
using System;

public class Program    
{
    struct A
    {
        public A(int x) : this()
        {
            X = x;
        }

        public int X { get; private set; }

        public void Update(int y)
        {
            X += y;
        }
    }

    class B
    {
        private A _secondVar;

        public B()
        {
        }

        public A MyVar { get; set; }

        public A SecondVar
        {
            get { return _secondVar; }
            protected set { _secondVar = value; }
        }           

        public void Foo(int z)
        {
            MyVar.Update(z);
            _secondVar.Update(z);
        }       
    }


    public static void Main()
    {
        B b = new B();
        Console.WriteLine("BEFORE: b.MyVar: " + b.MyVar.X + ", b.SecondVar: " + b.SecondVar.X );
        b.Foo(23);
        Console.WriteLine("AFTER: b.MyVar: " + b.MyVar.X + ", b.SecondVar: " + b.SecondVar.X );
    }

尝试使用scale(2)对我来说效果很好。

  

但是您需要根据需要更改translate() 值的scale() 值。

.column img{
    filter: brightness(0.8);
    transition: 0.6s ease;
}

.column:hover img{
    filter: brightness(0.5);
    transform: translate(50%,50%) scale(2);
    transition: 0.6s ease;
}
<div class="column">
    <a href="-----.html">
        <img src="https://picsum.photos/300/100/?random">
    </a>
</div>

仅当窗口悬停时，才可以在图像上设置过渡效果。这样，在调整大小时，它将不再影响您的元素，但是在元素的悬停和鼠标移出时，它仍将处于活动状态。

/* when hovering the page */
:hover .row .column img {
  transition: 0.6s ease;
}

.row .column img {
  background: #000000;
  width: 100%;
  filter: brightness(0.8);
  height: calc(80vh - 10px);
  /*  transition: 0.6s ease; [removed]*/
}

.row .column:hover img {
  /*  transition: 0.6s ease; [useless]*/
  width: 110%;
  cursor: pointer;
  transform: translate(-5%, -5%);
  filter: brightness(0.5);
  height: calc(80vh - 10px);
}

.column {
  float: left;
  position: relative;
  text-align: center;
  width: 50%;
  padding: 0px;
  overflow: hidden;
  height: calc(60vh - 10px);
}
<div class="row">
  <div class="column">
    <a href="---.html">
      <img src="https://picsum.photos/300/100/?random">
      <div class="centered">1</div>
    </a>
  </div>
  <div class="column">
    <a href="---.html">
      <img src="https://picsum.photos/300/100/?random" />
      <div class="centered">2</div>
    </a>
  </div>
</div>

但是使用这种解决方案，如果从文档本身鼠标移出，那么过渡也将被禁用...

不幸的是，除了使用js，我看不到其他解决方案。

(function(){
  let timer;
  const docEl = document.documentElement;
  addEventListener('resize', e => {
    clearTimeout(timer);
    docEl.classList.add('resizing');
    timer = setTimeout(_ => docEl.classList.remove('resizing'), 200);
  });
})();
:root.resizing .row .column img {
  transition: none;
}
.row .column img {
  background: #000000;
  width: 100%;
  filter: brightness(0.8);
  height: calc(80vh - 10px);
  transition: 0.6s ease;
}

.row .column:hover img {
  width: 110%;
  cursor: pointer;
  transform: translate(-5%, -5%);
  filter: brightness(0.5);
  height: calc(80vh - 10px);
}

.column {
  float: left;
  position: relative;
  text-align: center;
  width: 50%;
  padding: 0px;
  overflow: hidden;
  height: calc(60vh - 10px);
}
<div class="row">
  <div class="column">
    <a href="---.html">
      <img src="https://picsum.photos/300/100/?random">
      <div class="centered">1</div>
    </a>
  </div>
  <div class="column">
    <a href="---.html">
      <img src="https://picsum.photos/300/100/?random" />
