The style sheet of the navigator is used to establish the initial style by defect to all the elements HTML: sizes of letter, decoration of the text, margins, etc. This style sheet always is applied to all the pages Web, reason why when a page does not include any own style sheet, the aspect with which it is in the navigator must to this style sheet of the navigator.
