carlucci Do you mean on this 'Podcast' page? Actually, it's page heading and you can use this custom css code:
.view-podcast-list .page-header h1, .view-podcast-list .page-header .h1 {
max-width: initial !important;
text-align: center !important;
}
.view-podcast-list .page-header h1:after, .view-podcast-list .page-header .h1:after{
background-position-x: center;
width: initial !important;
}
