The <wbr> tag is used to instruct the browser, where in the text a line-break could be added. Unlike the <br> tag, which oblige the browser to insert a line-break, when <wbr> is used the browser first analyze its content, and then insert a line-break if necessary (too long word or URL address).
In case you do not use the <wbr> tag, long words could either wrap in a wrong place (making it difficult to read), or not wrap at all - pushing the page layout to the side.
The <wbr> tag is one of the HTML5 elements.
You may not use this element frequently. But if you need it, the <wbr> will be really useful. Let’s look through the example below, where we have a file path.
<p>You can find the file by going C:\user\docs\Letter.txt </p>
As you can see there isn’t any line-break opportunity, and the whole file path went to the next line. If you add <wbr> elements, the file path will break properly, while rendering that paragraph.
<p>You can find the file by going C:<wbr>\user<wbr>\docs<wbr>\Files<wbr>\Letter.txt</p>
The <wbr> tag is empty, which means that the closing tag isn’t required. But in XHTML, the (<wbr>) tag must be closed (<wbr/>).
Example of the HTML <wbr> tag:¶
<html> <head> <title>Title of the document</title> </head> <body> <p>Example of a long string of text without wbr.</p> <p>This is the longest word you can ever meet in the English language pneumonoultramicroscopicsilicovolcanoconiosis</p> <p>Example of a long string of text with wbr.</p> <p>This is the longest word you can ever meet in the English language pneumono<wbr>ultra<wbr>micro<wbr>scopic<wbr>silico<wbr>volcano<wbr>coniosis</p> </p> </body> </html>
