You can do something like this
d-header .title::after {
padding-left: 20px;
font-size: 1.5em;
color: #333;
content: "Here is some text";
}
You’ll still need to hide it where you don’t want it like when the title of a topic is displayed
You can do this by not having it display on pages with the archetype-regular body class (in which case it won’t be on topic pages at all) or with js that makes it disappear like how the Large and Small logos get swapped out once you start scrolling
