「テンプレート:Blockquote/doc」を編集中 (節単位)

== Limitations ==
{{anchor|Restrictions|reason=Old section name}}
If you do not provide text, the template generates a parser error message, which will appear in red text in the rendered page.

If any parameter's actual value contains an [[equals sign]] (<code>=</code>), you {{strong|must}} use a named parameter (e.g. <code>|text="E=MC<sup>2</sup>" is a formula everyone knows but few understand</code>, not a blank-name positional parameter. The text before the equals sign gets misinterpreted as a named parameter otherwise. Be wary of URLs, which frequently contain this character. Named parameters are always safer, in this and other templates.

If any parameter's actual value contains characters used for wiki markup syntax (such as [[vertical bar|pipe]], [[brackets]], single quotation marks, etc.), you may need to escape it. See {{tlx|!}} and friends.

=== Next to right-floated boxes ===
{{As of|2015|09|post=,}} the text of a block quotation may rarely overflow (in Firefox or other Gecko browsers) a right-floated item (e.g. a {{tlx|Listen}} box, when that item is below another right-floated item of a fixed size that is narrower. In Safari and other Webkit browsers (and even more rarely in Chrome/Chromium) the same condition can cause the block quotation to be pushed downward. Both of these problems can be fixed by either:
# removing the sizing on the upper item and letting it use its default size (e.g. removing <code>{{var|###}}x{{var|###}}px</code> sizing or {{para|upright}} from a right-floated image above a wider right-floated object that is being overflowed by quotation text; or
# using {{para|style|{{code|lang=css|code=overflow:inherit;}}}} in the quotation template.
There may be other solutions, and future browser upgrades may eliminate the issue. It arises at all because of the <syntaxhighlight lang="css" inline>blockquote {overflow: hidden;}</syntaxhighlight> CSS declaration in [[Mediawiki:Common.css]], which itself works around other, more common display problems. A solution that fixes {{em|all}} of the issues is unknown at this time.

=== Vanishing quotes ===
In rare layout cases, e.g. when quotes are sandwiched between userboxes, a quotation may appear blanked out, in some browsers. The workaround for this problem is to add {{para|style|{{code|lang=css|code=overflow:inherit;}}}} to such an instance of the template.

=== Line breaks ===
This template sets a text style which might ignore one blank line, and so the template must be ended with a break (newline) or the next blank line might be ignored. Otherwise, beware inline, as:<br />{{in5}}text here {{tlf|blockquote|this is quoted}} More text here<br />spans a blank line, unless a {{tlf|blockquote|...}} is ended with a line break, then the next blank line might be ignored and two paragraphs joined.

=== Nested quotations ===
The {{code|lang=html|code=<blockquote>...</blockquote>}} element has styles that change the font size: on desktop, text is smaller; on mobile, it is larger. This change is relative to the enclosing context, meaning that if you quote from a source that itself uses a block quotation, you'll find that the inner quotation is either really tiny and hard to read, or really large and barely fits on the screen. To fix this issue, add the parameter {{para|style|{{code|lang=css|font-size:inherit;}}}} on any inner {{tlf|blockquote}} templates.
