Section HeaderBLK

Introduces a section with a title, description, and optional action - start-aligned, centered or split, in three title sizes. Part of the Landing Page blocks.

Component Skill — components/section-header/component-skill.md

Native basis

A heading (h2) with an eyebrow, a description and optional actions (Buttons). flex-wrap lets the split layout fall back to a stack when the row gets narrow; a container query scales the title.

Built from

Button, Badge, Avatar, Kbd.

Data attributes

data-align="center", data-variant="split", data-size (sm, lg); data-variant (numbered + data-index, divider, banner); .mk-section-header-proof (an Avatar group + a sentence).

§Default

Eyebrow, title, description and an action, start-aligned. The title scales up once the section is 48rem wide.

§Centered

data-align='center' - for symmetric sections like pricing or testimonials.

§Split

data-variant='split': copy on the left, the action on the right of the baseline - narrow, it wraps under the copy.

§Sizes

data-size='sm' for sub-sections, 'lg' for the first section on a page.

§Numbered

data-variant='numbered' with data-index='01': a large outlined index leads - for chaptered pages (how it works, step by step).

§Divider

data-variant='divider': the title draws a rule to the edge - quiet separation between long sections.

§Banner with social proof

data-variant='banner' + data-align='center': a dotted surface. The eyebrow is a Badge, the actions are Buttons (one with a Kbd shortcut) and the proof line composes an Avatar group.
