CC PROBE PAGE v1 (2026-07-06). Each numbered box below tests one HTML construct. Compare source vs editor-after-save vs live.
T01 bare empty p (expect: CC adds data-text, may become visible block)

T01-CANARY-AFTER-BARE-P
T02 p containing only newlines and tabs (expect: visible ghost gap)

T02-CANARY-AFTER-WHITESPACE-P
T03 p with text plus trailing newlines/tabs inside the tag

T03 text with trailing whitespace inside the tag

T04 ghost box pattern: empty p, div with text, empty p

T04 the actual text between two empty p tags

T05 control: pre-tagged clean data-text p, no inner whitespace (expect: unchanged)

T05 clean control text

T06 divs nested 5 deep
T06 text five divs deep
T07 inline style attribute (expect: preserved)
T07 white text on red via inline style
T08 custom class styled from the CSS field (expect: green box if CSS field works)
T08 should have green background from CSS field rule
T09 heading stack h1-h4 (core.min.css strips heading margins)

T09 h1 heading

T09 h2 heading

T09 h3 heading

T09 h4 heading

T10 lists (core.min.css forces padding-left:0 !important)
  • T10 unordered one
  • T10 unordered two
  1. T10 ordered one
  2. T10 ordered two
T11 table
T11 head AT11 head B
T11 cell 1T11 cell 2
T12 image: 800px-wide data-URI svg in a 400px container (core.css clamps max-width; does CC rewrite src to lazy?)
T12 probe image
T13 inline SVG element
T13 inline svg
T14 button element vs styled anchor
T15 CTA anchors: first has NO href (correct CC pattern), second has href="#" (expect: href kills linkMethod binding)
T15 CTA without hrefT15 CTA with href
T16 style block INSIDE the HTML field (expect per 2026-06-17 finding: silently ignored, box stays white)
T16 magenta means HTML-field style blocks DO apply. White means ignored.
T17 script tag in HTML field (does the tag survive save, and does it execute live?)
T17 JS DID NOT RUN
T18 HTML comment on the next line (does it survive save?)
T18 text after the comment
T19 custom data-* attribute (expect: preserved)
T19 element with custom data attribute
T20 semantic tags section/article/aside
T20 section text
T20 article text
T21 special characters: smart quotes, entities, nbsp, emoji

T21 “entity smart quotes” and literal “smart quotes” and don’t and & and nbsp and 🔥

T22 br tags used as spacing

T22 line one
T22 line two

T22 after double br

T23 empty div spacer with fixed inline height (expect: survives, but does CC add data-text?)
T23-CANARY-AFTER-SPACER
T24 iframe embed
T25 form elements
T26 uppercase tag and attribute (does CC normalise case?)
T26 uppercase div tag
T27 pretty-printed LLM-style block: heavy indentation and newlines between and inside tags

T27 heavily indented paragraph text split across multiple source lines the way an LLM formats HTML

T27 second indented paragraph

T28 flexbox row via inline style (does .element-wrapper flex or column forcing interfere?)
T28 flex child A
T28 flex child B
T29 CSS grid from CSS field class (expect: 3 columns if CSS field grid works)
T29 cell 1
T29 cell 2
T29 cell 3
T30 CC native structure control: section > section_row > row-column with element-wrapper (expect: renders per CC conventions, width forced 100%)

T30 text inside CC native structure, column set to 50% width

T31 bootstrap grid row/col (CC provides Bootstrap 4.5)
T31 col-6 left
T31 col-6 right
T32 CC visibility classes (resize window: first line hides on desktop, second hides on mobile)

T32 no-desktop: visible on mobile/tablet only

T32 no-mobile: visible on desktop/tablet only
