CSS hover for after and before background images - html

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.

Answer 1

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'>
