Hello Benjamin,

Try custom css code below:

@media screen and (min-width: 900px) {
    .site-header .col-md-8:after {
        display: block;
        width: 100%;
        content: '#buenrollito';
        color: #fff;
        font-size: 45px;
        text-align: right;
        margin-top: 50px;
    }
}

@media screen and (max-width: 900px) {
    .site-header .col-md-8:after {
        display: block;
        width: 100%;
        content: '#buenrollito';
        color: #fff;
        font-size: 35px;
        text-align: right;
        margin-top: 50px;
    }
}

@media screen and (max-width: 767px) {
    .site-header .col-md-8:after {
        font-size: 45px;
        text-align: center;
    }
}
