Changing Link format in Enfold theme

Hi everyone, I’m trying to update the look and feel for my links. I’ve added some custom CSS to my style.css file and I’ve gotten the in-line text links to look how I like. Unfortunately, images are now showing a pink border around them. Can someone please help?

Here is a sample page: https://designinside.com/best-led-light-bulb-for-your-home/

Here is the CS I’m using:
.avia_textblock a {
color:#6c6c6c;
text-decoration:none;
text-decoration: none;
border-bottom: 6px solid #FEDDDA;
}
.avia_textblock a:visited {
color:#6c6c6c;
}
.avia_textblock a:hover {
color:#6c6c6c;
background: #FEDDDA;
}

Thanks in advance for the help
