Bản mẫu:Abbr/doc

== Cách sử dụng**
The template abbr and its tooltip variant take two unnamed parameters, in order:
1 or first unnamed parameter: the term to be explained; shows as text, and may use wikimarkup, such as a link to an article about what it refers to.
2 or second unnamed parameter: the expansion or definition or other note about the term; shows as the popup when you hover over the term. No wikimarkup can be used in this parameter.
Use explicitly numbered parameters if a parameter's content contains the equals () character:- Complex example: - Produces: 
Named parameters (usually not needed) and the input they take:
class: One or more CSS classes (space-separated if more than one)
id: An HTML id (i.e., a #ID name here link anchor); this must be unique on the entire page.
style: Arbitrary inline CSS to apply to the displayed text of the term (has no effect on the tooltip text). For any input that needs to be quotation-marked (e.g. because it contains a space character), use straight single-quotes only, e.g. font-family: 'Times New Roman', serif;

**Examples**

**Linking must be done a particular way**
To wiki-link the abbreviation being marked up by this template, wrap the template in the link, not vice-versa, or the meaning will not appear in some browsers, including Chrome. 
Do not link, or use any other wikimarkup or HTML markup, in the meaning (popup) – only plain text.
The mouse-over popup for the meaning text is created by a title= attribute inside an o HTML element's opening tag, so it cannot itself contain any HTML (or markup that resolves to HTML when rendered). This includes simple things like .

**Accessibility and HTML validity concerns**
template is intended only for use with abbreviations (including acronyms and initialisms).
The Web Content Accessibility Guidelines contain guidelines for using the o element generated by this template; see section  H28: Providing definitions for abbreviations by using the abbr and acronym elements.
Furthermore, the HTML specifications (both those of the W3C and WHATWG) strictly define the o element as reserved for markup of abbreviations.  Abusing it for mouse-over tooltips breaks our semantic markup and makes our content invalid HTML (technically, "not well-formed"; it will pass an basic automated validator test because such a tool can't tell that the logical application of the data to the structure isn't correct, only that tags are nested properly, etc.).
