Help:Lint errors/multiple-unclosed-formatting-tags

Problem
There are two unrelated instances where this category is emitted.

Scenario 1: Accumulated effect of small and big tags
When more than one &lt;small> or &lt;big> tag is left unclosed on a page, the effects of those small and big tags accumulate on a page. See this revision on Italian Wikipedia for an example of a particularly bad case with 13 unclosed small tags.

Scenario 2: Incorrect use of instead of
Sometimes, editors accidentally use an opening tag instead of a closing tag. For example (Ex: this revision on itwiki)

Solution
In both the scenarios, close the corresponding unclosed tag.

Affected tags
Note that these scenarios only affect formatting tags (,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  , and  ).

Caveats

 * 1) This error is expected to not be very common.
 * 2) There can be false positives if the unclosed small / big tags are in different cells of a table.
