[Lead role attibute](https://docs.asciidoctor.org/asciidoc/latest/blocks/preamble-and-lead/#lead-role) now do nothing at default ui as i see src/css/vars.css :root { /\* fonts \*/ \--rem-base: 18; } src/css/doc.css .doc .paragraph.lead \> p { font-size: calc(18 / var(--rem-base) \* 1rem); } make font-size: calc(24 / var(--rem-base) \* 1rem); so it have real difference at ui {width="900" height="320"} {width=281 height=198}
