Applying CSS Rules

 

How to apply CSS Rules:

  §  In This tutorial we will discuss how to apply CSS to the HTML elements.

  §  We can apply CSS to html element just by defining the CSS rules.

  §  A CSS comprises of style rules that are interpreted by the browser and then applied to the corresponding elements in your document.

  §  CSS rule is made up of two parts.

      · Selector·   Declaration

Selector

  §  With the help of the selector, we Identifies the HTML elements at which the CSS rule is to be applied correctly .i.e. identified by the actual element name, e.g. <body>, <p>, <h1>

    Declaration

  §  Declaration part contains property and value.

    Property

  §  The properties are the style attribute put simply, all the HTML attributes are converted into CSS properties. They could be color, border etc.

    Value

  §  Values are assigned to properties. For example, color property can have value either  red or #F1F1F1 etc.

    Example: -

  §  Suppose that we want size of our text 10px then it declare as font-size: 10px. Here font-size is properties and 10px is there value, and all this declaration is called declaration.

Syntax:

Note:

  §  With-in Declaration Block we specify the declaration of property. The declaration is also split into two parts, they are separated by a colon " : " i.e.  property and value  is separated by colon ":"

  §  However, because a declaration can consist of several property - value pairs, and each property - value pair within a rule must be separated by a semicolon.
