CSS箭头过渡

Question

我有一个从右到左的 CSS 箭头。我首先有箭头，然后是文本。我试图在悬停时实现以下过渡：悬停，左侧的箭头消失并出现在文本之后的右侧。如何实现鼠标悬停时箭头出现在右侧的效果？

我正在尝试实现this 效果，但方向相反

body {
  background: black;
}

.the-arrow {
  width: 64px;
  transition: all 0.2s;
  transform: rotate(180deg);
}

.the-arrow.-left {
  position: absolute;
  top: 60%;
  right: 0;
}

.the-arrow.-left .shaft {
  width: 0;
  background-color: #999;
}

.the-arrow.-left .shaft:before,
.the-arrow.-left .shaft:after {
  width: 0;
  background-color: #999;
}

.the-arrow.-left .shaft:before {
  -webkit-transform: rotate(0);
  transform: rotate(0);
}

.the-arrow.-left .shaft:after {
  -webkit-transform: rotate(0);
  transform: rotate(0);
}

.the-arrow.-right {
  top: 3px;
}

.the-arrow.-right .shaft {

Answer 1

只是为了好玩，用一个伪和过渡使它更短

body {
  background: black;
  color:purple;
  font-size:2em;
}

a {
  color: #fff;
  font-size: 12px;
  text-decoration: none;
  position: relative;/* to be the reference for the absolute pseudo */
  display:inline-block;/* to size it and set horizontal margin */
  vertical-align:middle;
  background:black;
  margin:0 68px;
  padding:0 0.25em;
}

.animated-arrow::before {
  content:'\0003c';/* the sign < to draw edge of the arrow */
  font-size:16px;/* might need to be resized */
  /*display:inline-block; if not absolute */
  width:64px;/* that was your value, equal at the most to the margin of parent link  */
  background:linear-gradient(to bottom, transparent 50%,currentcolor 50%,  currentcolor calc(50% + 1px) , transparent  calc(50% + 1px));/* to draw the body arrow */
  top:-0.15em;/* if needed */
  position:absolute;/* , so coordonate are easier to set */
  z-index:-1;/* let slide under the link */
  right:100%;
  transition: right  0.2s, transform 0.1s 0s;
}
.animated-arrow:hover::before {
  right:-64px;
  transform:scale(-1,1)
} 
a+a {color:gold;}

<a class="animated-arrow arrow-c-f" href="#">Some cool Text</a> ⊛
<a class="animated-arrow arrow-c-f" href="#">Some cool Text of any length</a>

Answer 2

使用单个元素

*{  
  box-sizing: border-box
}
body{padding: 4rem}
.arrow{
  position: relative; 
  display:inline-block
}

.arrow:before,
.arrow:after{
  content: "";
  position: absolute;
  top: 50%;
  transition: all 0.2s;
}
.arrow:before{
  right: 100%;
  width:32px;
  height:1px;
  background: black;
}
.arrow:after{
  width:12px;
  height: 12px;
  border-top: 1px solid black;
  border-left: 1px solid black;
  right: calc( 100% + 16px );
  transform: rotate(-45deg);
  margin-top: -6px;
}

.arrow:hover:before{
  right: -32px
}
.arrow:hover:after{
  transform: rotate(-45deg) scale(-1);
  right: -32px;
}

<div class="arrow">some cool text</div>

Answer 3

我删除了一些元素，有点用箭头作弊。

/* So it's easier to change spacing */
:root {
  --spacing: 1rem;
  --spacing-half: calc(var(--spacing) / 2);
  --spacing-quarter: calc(var(--spacing) / 4);
}

body {
  background: black;
  color: #fff;
  font-family: 'Montserrat';
}

a {
  font-size: 12px;
  text-decoration: none;
  color: #fff;
}

.text {
  padding: var(--spacing-quarter);
  text-transform: uppercase;
}

.text,
.animated-arrows
{
  display: inline-block;
}

.animated-arrows::before,
.animated-arrows::after {
  position: relative;
  vertical-align: text-bottom;
  
  transition: left 600ms, opacity 800ms;
}

.animated-arrows::before {
  content: '⟵';
  left: 0rem;
}

.animated-arrows::after {
  content: '⟶';
  opacity: 0;
  left: calc(-1 * var(--spacing-half));
}

/* Animation changes */
.animated-arrows:hover::before {
  left: var(--spacing-half);
  opacity: 0;
}

.animated-arrows:hover::after {
  left: 0rem;
  opacity: 1;
}

  <a href="#">
    <div class="animated-arrows">
      <div class="text">Some cool Text</div>
    </div>
  </a>

所以我已经设法解决了这个问题：

body {
