The W3C box model defines a model for laying out and positioning elements in CSS. The standard W3C box model includes the following components:

1. Content (content area): refers to the actual content of the element, such as text, pictures, etc. The size of the content area can be controlled by setting the width and height properties.

2. Padding: The blank area between the content area and the border. The size of the padding can be controlled by setting the padding property.

3. Border: A line or border surrounding content and padding. The style, thickness and color of the border can be controlled by setting the border property.

4. Margin: The blank space between the border and adjacent elements. The size of the margins can be controlled by setting the margin property.

These components form a rectangular box used to position and layout elements. In the standard W3C box model, the width and height attributes specify the size of the content area, while the padding, border, and margin attributes increase the size of the rectangular box. This is different from the IE box model, which includes the padding and border sizes in the width and height properties.

By understanding and applying the W3C box model, developers can better control the layout and style of elements, achieving more flexible and precise page design.
