CSS 悬停在背景图像之前和之后

Question

when you hover over the image blue arrow moves slowly. When you remove the cursor from the image white arrow comes back sharply. How to make a white arrow return slowly?

 @keyframes left_to_right { from {margin-left: -15px;} to {margin-left: 0; } } div .footer-text{ position: absolute; top: 10%; left: 3%; height: 20px; width: 85%; } div .footer-text:after{ content: ''; background: url('https://www.nsartmuseum.ru/images/test/arrow-after-3.png') no-repeat; width: 130px; height: 15px; display: inline-block; margin-left: 10px; position: relative; } div:hover .footer-text:before{ content: ''; background: url('https://www.nsartmuseum.ru/images/test/arrow-before-3.png') no-repeat; width: 130px; height: 15px; margin-right: 5px; display: inline-block; animation: left_to_right 0.4s ease; } div:hover .footer-text:after{ content: ''; background: none; } div .footer-text span{ position: relative; top:-5px; font-size: 12px; color: #313B78; display: inline-block; }

 <div> <a href="" class='footer-text'> <span>13 September</span> </a> </div>

Obviously, there are ways to do this by CSS animation, but I've never used this in my development.

It's not required to use animation for that. transition is enough just add transition: width .4s ease; to :after for unhovered element and play with width attribute

 div .footer-text{ position: absolute; top: 10%; left: 3%; height: 20px; width: 85%; } div .footer-text span{ position: relative; top:-5px; font-size: 12px; color: #313B78; display: inline-block; } div .footer-text:after{ content: ''; background: url('https://www.nsartmuseum.ru/images/test/arrow-after-3.png') no-repeat right; width: 130px; height: 15px; display: inline-block; margin-left: 10px; position: relative; transition: width .4s ease; } div:hover .footer-text:after{ width: 0; } div .footer-text:before{ content: ''; background: url('https://www.nsartmuseum.ru/images/test/arrow-before-3.png') no-repeat right; width: 0; height: 15px; margin-right: 5px; display: inline-block; transition: width .4s ease; } div:hover .footer-text:before{ width: 130px; }

 <div> <a href="" class='footer-text'> <span>13 September</span> </a> </div>
