For that go to the “base.css” file and find this CSS in line number “2883”
.badge {
border: 1px solid transparent;
border-radius: var(--badge-corner-radius);
display: inline-block;
font-size: 1.2rem;
letter-spacing: 0.1rem;
line-height: 1;
padding: 0.5rem 1.3rem 0.6rem 1.3rem;
text-align: center;
background-color: rgb(var(--color-badge-background));
border-color: rgba(var(--color-badge-border), var(--alpha-badge-border));
color: rgb(var(--color-badge-foreground));
word-break: break-word;
}
and replace the " font size 1.2rem" to 1.3rem or 1.4rem according to your requirement.
you can also give it in pixel e.g- 15px
Thanks
