element

mmo-specimen

One specimen of the design system: a live example, and the html that produced it.

<mmo-specimen label="" note="" ground="surface" layout="row" code="open"></mmo-specimen>

Extends: CustomShadowElement

The example is the element's own light dom, shown through a `<slot>` -- so it is painted by the document's stylesheet, which is the only place `.button`, `.card` or `.tag` exist. A shadow root sees none of that css, so anything copied into one would be a second, drifting copy of the design system; slotting the real markup is what makes a specimen show the real thing. The code panel is that same markup, read back from the light dom, dedented and highlighted -- so the html shown can never say something different from what is rendered above it. ```html <mmo-specimen label="Tones" note="one filled recipe, six hues"> <button class="primary">Save</button> <button class="error">Delete</button> </mmo-specimen> ```

Properties2

tocTimer

staticmmo-specimen.jhs:52

one rebuild of the page's table of contents for all the specimens of a page, not one each

static tocTimer = null;

Type: string

Methods9

constructor()

mmo-specimen.jhs:54

constructor()

init()

mmo-specimen.jhs:59

init()

load()

mmo-specimen.jhs:69

Read the example back from the light dom and fill the code panel.

load()

returns void

clean(html)

mmo-specimen.jhs:85

What the page's own tooling wrote into the example on its way past -- the id a table of contents anchors a heading with. It is not part of the specimen's html, so it is not shown as if it were.

clean(html)

html	`string`
returns	`string`

hideFromToc()

mmo-specimen.jhs:94

The headings of an example are not sections of the page. Mark them, drop the anchors a table of contents may already have given them, and ask it to rebuild -- once for the whole page.

hideFromToc()

returns void

dedent(html)

mmo-specimen.jhs:114

The markup as a page would write it: tabs expanded, the blank lines around it dropped and the template's own indentation taken off, so the html reads from column zero whatever depth the specimen sits at in the page.
