The id attribute is supported in all major browsers.
The id attribute specifies a unique id for an HTML element (the value must be unique within the HTML document).
In HTML5, the id attribute can be used on any HTML element (it will validate on any HTML element. However, it is not necessarily useful).
In HTML 4.01, the id attribute cannot be used with: <base>, <head>, <html>, <meta>, <param>, <script>, <style>, and <title>.
Note: HTML 4.01 has greater restrictions on the content of id values (for example; in HTML 4.01 id values cannot start with a number).
