 # CSS ::contents pseudo-element proposal
 
-All non-replaced elements have a `::contents` pseudo-element, which wraps all the contents inside the element, not including contents generated by [`::before`](https://www.w3.org/TR/css-pseudo-4/#selectordef-before) and [`::after`](https://www.w3.org/TR/css-pseudo-4/#selectordef-after).
+All non-replaced elements have a `::contents` pseudo-element, which wraps all the contents inside the element, not including [`::marker`](https://drafts.csswg.org/css-pseudo-4/#marker-pseudo) nor the contents generated by [`::before`](https://www.w3.org/TR/css-pseudo-4/#selectordef-before) and [`::after`](https://www.w3.org/TR/css-pseudo-4/#selectordef-after), if any.
 
 `::contents` pseudo-elements must act as if they were assigned [`display: contents`](https://www.w3.org/TR/css-display-3/#valdef-display-contents) via a rule in the UA origin. Therefore, they do not generate any boxes and are treated as if they had been replaced with their children. This must be possible to override via [`display`](https://www.w3.org/TR/css-display-3/#the-display-properties), so they do generate boxes if desired.
 
 > **Note**
 > This is consistent with [slots in a shadow tree](https://drafts.csswg.org/css-scoping/#slots-in-shadow-tree).
 
 A `::contents` pseudo-element can be styled exactly like any normal document-sourced element in the document tree.
-When its [`display`](https://www.w3.org/TR/css-display-3/#the-display-properties) property does not compute to [`contents`](https://www.w3.org/TR/css-display-3/#valdef-display-contents) nor [`none`](https://www.w3.org/TR/css-display-3/#valdef-display-none), the pseudo-element generates boxes as if it was an immediate children of its originating element. When its [`display`](https://www.w3.org/TR/css-display-3/#the-display-properties) property computes to [`none`](https://www.w3.org/TR/css-display-3/#valdef-display-none), the pseudo-element and the contents of the originating element generate no boxes.
