Why are there slashes in this div id?

Question

I was browsing a site and found this line of code:

<div class="section slideshow" id="/featured/">

I've never seen slashes in an id tag before, is this poor coding, a problem written out by the database, or something else?

Answer 1

Slashes in an id attribute is not a valid character:

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

Answer 2

Maybe to use it directly in an url and/or with javascript...

Answer 3

Maybe he use this method for insert to database(insert id in a string) or go to an url .

Slashe is not a valid character for ID in html 4.01 but its valid in html5 .

For html 4.01

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").
