How Web browsers should display page elements such as text and graphics.
A CSS style rule consists of two parts—the selector and the declaration. The selector is the name of the style (such as TR, or P) and the declaration defines what the style elements are. The declaration consists of two parts, the property (such as font-family), and value (such as Helvetica).

A major advantage of CSS styles is that they provide easy update capability; when you update a CSS style, the formatting of all the documents that use that style are automatically updated to the new style.

The building block of a database is the record. A record is a collection of related data treated as a single entity. For example, a hockey trading card could be called a record: it brings together the name,

A collection of records that share the same fields is called a table because this kind of information can easily be presented in table format: each column represents a field and each row represents a record.

A database can contain more than one table, each with a unique name. These tables can be related or independent from one another.

A subset of data extracted from one or more tables is called a recordset (or a DataSet in ASP.NET). A recordset is also a table because it’s a collection of records that share the same columns. .

The term cascading refers to your ability to apply multiple style sheets to the same web page. For example, you can create one style sheet to apply color and another to apply margins, and apply them both to the same page to create the design you want.
