Template:Block indent is permanently protected from editing because it is a heavily used or highly visible template. Substantial changes should first be proposed and discussed here on this page. If the proposal is uncontroversial or has been discussed and is supported by consensus, editors may use {{edit template-protected}} to notify an administrator or template editor to make the requested edit. Usually, any contributor may edit the template's documentation to add usage notes or categories.
Any contributor may edit the template's sandbox. Functionality of the template can be checked using test cases.

Reason, the example of this in the documentation should show as in an article?
Plus I have display problem requires a leading <b r />line-break.
I will be importing some items from my own talk page to illustrate the problem shortly, but the short of it is that if content is not wrappable (or is an image, say) then if the screen is narrow enough (like a phone) then any textual or image data is lost to the beyond (the edges of the screen) without any scrolling capabilities. :- indentation with <math> as is often paired allows sideways scrolling of the image. So does the display="block" attribute in the math tag. But say for {{math}} or some other situation where indent is required and :-indentation is discouraged, this template is the ideal candidate. Except when the content is too wide. Hellacioussatyr (talk) 16:56, 30 April 2021 (UTC)[reply]
As stated in my talk page, the formula on Duality (mathematics) is only partially viewable. The workaround here was to use the display="block" attribute, but <math> isn't the only form of math formatting in use. (The CSS class rules for .block-indent has a rule overflow: hidden. May that have anything to do with this issue?) Hellacioussatyr (talk) 10:51, 1 May 2021 (UTC)[reply]
Why the default indent is chosen so? It is incompatible with the current practice if using : – "most editors have used it almost everywhere for indenting" – which is condemned but very widely used (including WP:MOS itself).
