The definition and application of a style involves
two facets or parts,
selector and
declaration. While the selector determines the area of the webpage
that needs to be styled,
the declaration block describes the style specifications that have to be implemented. In
order
to illustrate how it works, let us consider the following example,
body {
color: white;
}
In this example, the selector selects the body of the webpage and
the declaration block
defines that the font color should be changed to white. This
is a simple example and
declarations and selectors can be much more complex than this.
