Question

我正在尝试从以下网站复制此对角箭头动画：https://robertsspaceindustries.com/

这是一个小样板：https://jsfiddle.net/randal923/x0ywchq5/8/

我不确定什么是放置箭头以及如何为其设置动画的最佳方法。预先感谢。

Answer 1

这是一个使用多重背景创建箭头的想法，然后为位置的原点设置动画以创建所需的效果：

.box {
  width:200px;
  height:200px;
  padding:20px;
  box-sizing:border-box;
  background:
      linear-gradient(#000,#000) top left,
      linear-gradient(#000,#000) top left,
      linear-gradient(#000,#000) bottom left,
      linear-gradient(#000,#000) bottom left,
      linear-gradient(#000,#000) bottom right,
      linear-gradient(#000,#000) bottom right,
      linear-gradient(#000,#000) top right,
      linear-gradient(#000,#000) top right,
  red;
  background-size:20px 2px,2px 20px;
  background-origin:content-box;
  background-repeat:no-repeat;
  transition:0.3s all;
}
.box:hover {
  padding:5px;
}

<div class="box">

</div>

以图片为背景：

.box {
  width:200px;
  height:200px;
  position:relative;
  background: url(https://picsum.photos/800/600?image=1069) center/cover;
}

.box:before {
  content:"";
  position:absolute;
  top:0;
  left:0;
  right:0;
  bottom:0;
  padding:20px;
  background:
      linear-gradient(#000,#000) top left,
      linear-gradient(#000,#000) top left,
      linear-gradient(#000,#000) bottom left,
      linear-gradient(#000,#000) bottom left,
      linear-gradient(#000,#000) bottom right,
      linear-gradient(#000,#000) bottom right,
      linear-gradient(#000,#000) top right,
      linear-gradient(#000,#000) top right;
  background-size:20px 2px,2px 20px;
  background-origin:content-box;
  background-repeat:no-repeat;
  transition:0.3s all;
}
.box:hover:before {
  padding:5px;
}

<div class="box">

</div>

尝试此代码，我认为这对您有用。

* {
  margin:0;
  padding:0;
}

body {
  background:#ccc;
  font-family: arial,verdana,tahoma;
}

.animation {
  width: 705px;
  height: 333px;
  overflow:hidden;
  
  margin: 100px auto;
  -webkit-box-shadow: 0 8px 6px -6px black;
  -moz-box-shadow: 0 8px 6px -6px black;
  box-shadow: 0px 8px 6px -6px black;
}
/* .animation ul {
  
} */
.animation li {
  position: relative;
  display:block;
  width:140px;
  float: left;
  
  border-left: 1px solid #888;
  -webkit-box-shadow: 0 0 25px 10px rgba(0,0,0,0.5);
  -moz-box-shadow: 0 0 25px 10px rgba(0,0,0,0.5);
  
  transition: all 0.5s;
  -webkit-transition: all 0.5s;
  -moz-transition: all 0.5s;
}


.animation ul:hover li {
  width: 50px;
}

.animation ul li:hover {
  width:500px;
}

.animation li img {
  display: block;
}

.image_title {
  background: rgba(0,0,0,0.5);
  position:absolute;

.image_title a {
  display: block;
  color: #fff;
  text-decoration: none;
  padding:20px;
  font-size:16px;
}

<div class="animation">
  <ul>
    <li>
      <div class="image_title">
