Blockquote footer font size is currently hardcoded to 80%, implying (in a comment) that this would result in the default font size. However, since the blockquote font size itself is variable, this is not necessarily true, and 80% of anything actually results in an arbitrary font size.
80% as a default is still fine.
.blockquote-footer {
display: block;
- font-size: 80%; // back to default font-size
+ font-size: $blockquote-small-font-size;
color: $blockquote-small-color;
&::before {
$text-muted: $gray-600 !default;
$blockquote-small-color: $gray-600 !default;
+$blockquote-small-font-size: $small-font-size !default;
$blockquote-font-size: ($font-size-base * 1.25) !default;
$hr-border-color: rgba($black, .1) !default;
