Preface
While is always accessible, it's very inaccurate and inconsistent. Also, as evident by many differences in lists, not all tags are available everywhere. This guide aims to make the differences clearer, as well as point out parsing issues to watch out for.

Recommendations
  • Until character count is consistently implemented across Steam, add-ons like Word Count[addons.mozilla.org] are recommended to track it without relying on an external editor.
  • An alternative for guide section contents is Lutymane's Extended-Guide-Editing[github.com] userscript that removes the character limit, which requires a userscript loader add-on such as Violentmonkey[addons.mozilla.org] (edit: it doesn't seem to work any longer!).
  • Textarea Tabbing[addons.mozilla.org] is another recommendation, it can be used to indent hard to navigate code without wasting as many available characters using tabs instead of regular spaces.
  • Steam - unhide removed links[userstyles.world] userstyle reveals the contents of removed links, and requires a userstyle loader add-on such as Stylus[addons.mozilla.org].

Example
[h1] Heading 1 [/h1]
[h2] Heading 2 [/h2]
[h3] Heading 3 [/h3]

Note: Heading 2 and Heading 3 are not documented and have no accompanying button, Heading 1 can't be used in certain cases where it's documented otherwise.

[url=store.steampowered.com] Website link [/url]

Paste any (external or otherwise) URL for it to become a hyperlink.
lightwo.net
https://gtm.steamproxy.vip/discussions/

Note: external domain text can be worked around by using the link filter URL and adding a colon (:) after the gtm.steamproxy.vip domain, using it for the URL tag

id=anchor makes an anchor (unavailable)
Steam URLs or approved domains

Third party domains[lightwo.net]

Plain URLs

Note: a [table] element with no cells can be used to create a closed section, especially useful for left- and right-aligned images.

noborder and equalcells can't be used anywhere in Community editable by a normal user (excl. News and Support articles), despite being included in formatting help

sizeOriginal (original size)

Alignment:
floatLeft (left)
floatRight (right)
inline (inline)

[previewicon] respects breaks but isn't supposed to open modal window

[screenshot=420;https://...]Alt text[/screenshot]

Note: a custom thumbnail can be used by replacing the URL. Externally hosted images may be used by replacing the URL with a custom one, working around guide image storage limit
Alt text

Size and alignment:
same as above

[previewyoutube=tax4e4hBBZc;leftthumb][/previewyoutube]

Note: full width doesn't take tables and quotes into account

[previewyoutube=video_ID;full]

[previewyoutube=video_ID;rightthumb]
will align the video right
Paste a Steam Inventory Item URL to automatically generate a widget.
https://steam.../inventory/#440_2_11198320657

Note: new preview generation is broken for inventory AppIDs with many items, presumably due to reaching cache storage limit
(Usually broken)

Where To Use
Warning: Limits may be inaccurate
Likely due to the 2022 Winter Sale, some limits on Steam have been adjusted, and this section hasn't yet been edited to reflect that, considering it may be a temporary change. Here's some information on that.

Short summary
  • h1 can't be used in comments and activity posts, but h2 and h3 can.
  • h2, h3, img, video and Inventory Item URL aren't documented anywhere or have accompanying buttons.
  • Most formatting help pages are missing tables.
  • Group summaries aren't as bare as formatting help suggests.
  • img is exclusive to user-generated content description/summary.

You can't.
bloodization 20 Aug @ 10:22am 
I have sveral table in a guide. How to make it consistents size?
lightwo  [author] 26 Jul @ 1:35pm 
Poster refers to preview image, but since clicking the video doesn't make it play, it is useless in guides
OstinFCT 24 Jul @ 12:37pm 
How work "poster=thumbnail_url.png (clicking does nothing)"?
Sydewindr 1 May @ 11:15am 
Alright thanks bud :steamthumbsup:
lightwo  [author] 1 May @ 10:20am 
Nope, that feature doesn't exist to my knowledge.
Sydewindr 1 May @ 10:02am 
Hello, how did you managed to set the width of columns in tables? I've tried like [th:50]Column title[/th] but that doesn't seem to work.
lightwo  [author] 28 Feb @ 11:02am 
o_o

If I hadn't abandoned the Steam variant of this guide, it would've been really useful :thXD:

Yeah, sorry, my knowledge is mostly inapplicable to guides and stuff, since my field is mainly announcements and store page descriptions.
I’ve now made a guide to test stuff and indeed almost nothing works there :( Even colspan/rowspan for table cells.

But {date} tag does :) It also works on the forum, but alas not in the announcements, so i’m jealous :D i’ve asked Support to add it long ago — it would be pretty handy to describe maintenance times for example.

So example:
{date}1707323408{/date}
would display
"7 Feb, 2024 @ 4:30pm"
if user is using English and his timezone is UTC. The value is a unix timestamp.

It’s hardly useful for guides though i guess
lightwo  [author] 28 Feb @ 2:04am 
Yeah, paragraph tag is the only tag which I found to work here. I don't really see the purpose as it's broken and doesn't have a font set in some scenarios, and this is all preformatted text anyway, I can't imagine scrapers or screen readers behaving much differently in either case.
