based on sass
.activity-badge-card-description {
top: 68px;
position: absolute;
left: 0px;
width: calc(100% - 0px);
font-style: italic;
height: 73px;
line-height: 14px;
overflow-y: auto;
overflow-x: auto;
border: 1px solid #ddd;
margin: 0px;
padding-left: 2px;
padding-right: 2px;
}
you could do this with some css.
you need to have a max-height, and allow it to scroll.
.yourclass{
max-height: 200px;
overflow-y: auto;
}
