只是一个小变化对你的代码。

.trial:before { 
    content: ""; 
    border-bottom: 1px solid rgba(211, 211, 211, 0.54); 
    width: 130%; 
    display: inline-block; 
    vertical-align: middle; 
    position: absolute; 
    left: -15%; 
    top: 50%; 
    z-index: -1 !important; 
} 

.trial { 
    font-size: 15px; 
    font-weight: 600; 
    padding: 2px 21px 2px 21px; 
    color: #33c4b6; 
    border: 1px solid #e4e4e4; 
    display: inline-block; 
    border-radius: 15px; 
    background-color: white; 
    position: relative; 
    margin: 20px 0px 20px 0px;
