Hi saibharadwaj
Try to add to your custom.css this snippet of css code
.item-page .article-title a {
display: inline-block;
background: -webkit-linear-gradient(135deg, #fd7d56, #fc2372);
background: linear-gradient(135deg, #fd7d56, #fc2372);
background-clip: text;
font-family: EdoSZ, Helvetica, Arial, sans-serif;
line-height: 1.0666;
margin-top: 0;
text-fill-color: transparent;
-webkit-background-clip: text;
