What is CSS ID?
An ID in CSS is identified by the octothorpe symbol (#). An ID in CSS references the ID attribute in HTML and they should have the same name. For example lets say I have the following code in my HTML: <small id="copyright">Copyright &#169;2015 &#8212; David Trower. All Rights Reserved.</small> Notice the id="copyright" on the <small> element? That is the ID. In CSS, if I want to stylize this element by referencing that ID I would use the following CSS code: #copyright { color: #9CBDDE; } Notice how what follows the octothorpe (#) symbol in the CSS code is the same as the value of the ID attribute in HTML (both are the word copyright). An ID is to be a unique identifier within a document. It should appear once, and only once, within a single document.

What are key attribute and non key attribute?
Attributes can be classified as identifiers or descriptors. Identifiers, more commonly called keys or key attributes uniquely identify an instance of an entity. If such an attribute doesn't exist naturally, a new attribute is defined for that purpose, for example an ID number or code. A descriptor describes a non-unique characteristic of an entity instance. An entity usually has an attribute whose values are distinct for each individual entity. This attribute uniquely identifies the individual entity. Such an attribute is called a key attribute. For example, in the Employee entity type, EmpNo is the key attribute since no two employees can have same employee number. Similarly, for Product entity type, ProdId is the key attribute. There may be a case when one single attribute is not sufficient to identify entities. Then a combination of attributes can solve this purpose. We can form a group of more than one attribute and use this combination as a key attribute. That is known as a composite key attribute. When identifying attributes of entities, identifying key attribute is very important.
