Add CORP headers to media repo (#1197)
* Add CORP headers to media repo MSC: https://github.com/matrix-org/matrix-spec-proposals/pull/3828 * Write weird CSS rules to make added-in work inline in the CS spec Even though our content doesn't need 2 paragraphs, it's good to have the capability to render it in the future. * Remove test paragraph * Refine prose * spelling is key

"Temporary" shortcode for rendering paragraphs which want/need inline added-in tags. It is
|
||||||
|
assumed that your content is described as follows:
|
||||||
|
|
||||||
|
{{% boxes/added-in-paragraph %}}
|
||||||
|
{{< added-in v="1.4" >}} Your text here
|
||||||
|
|
||||||
|
{{< added-in v="1.4" >}} Your other text here
|
||||||
|
{{% /boxes/added-in-paragraph %}}
|
||||||
|
|
||||||
|
The assumption is that at a later date this added-in-paragraph shortcode can be removed, making
|
||||||
|
the angle bracket-defined added-in shortcodes *just work*.
|
||||||
|
|
||||||
|
It is important that each new "content" paragraph (the bit after added-in) is preceded with
|
||||||
|
and added-in, otherwise you might find your text being weirdly merged.
|
||||||
|
|
||||||
|
This exists while the added-in shortcode cannot be inline in the client-server spec.
|
||||||
