You have this CSS:
.verified-user .comment-author cite::after {
content: 'Sanu Replied';
margin-left: 640px;
text-align: right;
background: #FF6200;
color: #fff;
padding: 10px;
font-size: 15px;
}
replace that with:
.verified-user .comment-author-info {
width: 100%;
}
.verified-user .comment-author cite {
display: flex;
width: 100%;
justify-content: space-between;
}
.verified-user .comment-author cite::after {
content: 'Sanu Replied';
text-align: right;
background: #FF6200;
color: #fff;
padding: 10px;
font-size: 15px;
}
