Syntax

Each CSS property written in the following general form:

{Svoystvo1 selector: arguments; svoystvo1: arguments}


Selector called the style name, which specifies the formatting options, they are divided into several types: selectors tag IDs and classes.


Selectors are used to determine the tag style tags embedded HTML. Classes are used to create styles that can be applied to any tag HTML, to make a selection or change the style of the text block. Identifiers are typically used in conjunction with the scripts to be able to control the parameters dynamically style, moreover, each identifier within the page must be unique.

P {color: green; background: # f0f0f0; }

P {color: green; }

P {background: # f0f0f0; }


The first line for the selector P at the same time set the text color and background, and the second - at the beginning sets the color of text, and then background color. Since the selector specified one, but different properties, they will be applied simultaneously. Therefore, given the form record parameters lead to the same result.

P {color: green}

P {color: red}
