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.
