Template:Visible anchor/doc

The template inserts one or more HTML anchors in a page. Those locations can then be linked to using  syntax. Unlike Anchor, the first parameter will be visible text on the page.

Usage
The template can be used with up to 10 anchor names. Anchor names are case sensitive, so  and   are not equivalent. When making an anchor, in general capitalize the first letter of the anchor name, and follow the same capitalization guidelines as headers (see Manual of Style: Headers for more information). An optional text parameter can be added in order to specify the text to display in the anchor. By default, the value of the first parameter is used. A second optional lang parameter can be added to mark up the resulting visible text with the specified ISO 639 language code or IETF language tag (such as used by lang). The redirect vanchor can also be used.

Linking to anchors
Link to an anchor in the same article using just the anchor name, e.g. . (In the Visual Editor, type   into the link field.)

From a different article, link to an anchor by specifying the article name, followed by a, then the anchor name. e.g..

The  will be visible in the link text. To prevent this, give the link a display title in the typical manner: After a pipe character in the wikitext, or by editing the text of the link in the Visual Editor.

Destination highlighting
When a link to an anchor is followed, the destination anchor's visible text will typically be highlighted with a shaded background. (May vary based on the reader's browser or selected wiki skin.) For example:"this will be highlighted after following this link which targets it."

Specifying a language
To aid screen readers and other assistive technologies properly identify text in foreign languages or dialects, an ISO 639-1 language code or IETF language tag can be given with the lang parameter to add the language code as an attribute to the HTML of the displayed text. Note that unlike the lang template, no italicization or text formatting is applied to the text.

Limitations

 * Doing so will result in broken links in edit summaries, as well as possible duplicate anchors (see below).
 * Anchor names should be unique on a page, and should not duplicate any heading titles. Duplicate anchors won't work as expected since the #links go to the first anchor with that name. Duplicate anchors also result in invalid HTML; you can check for duplicate anchors by running the page through the W3C Markup Validation Service.
 * Anchor names that contain any character shown in the table on the right will not work as expected. However, any of these characters can be replaced with the "&amp;#" codes shown for them here. Or, the pipe symbol and equals sign can be worked around with ! and =, respectively. Markup code such as and  (superscript and subscript) cannot be used. Most other characters, including white space and punctuation, are not a problem.
 * The template can create a maximum of 10 anchors. Specifying more than 10 anchors will result in an error message.
 * If positional parameters (parameters without specifying 1=, 2=, etc.) are used, whitespace and newlines will be preserved. If you instead specify the name of the parameters (e.g. 1), whitespace and newlines will be trimmed.
