Universal CSS Selector

Lecture



Sometimes it is required to set simultaneously one style for all elements of a web page, for example, to set a font or a text style. In this case, the universal selector that matches any element of the web page will help.

An asterisk (*) symbol is used to denote a universal selector, and in general, the syntax is as follows.

* {Description of style rules}

In some cases, it is not necessary to specify a universal selector. For example, the entries * .class and .class are identical in their results.

Example 14.1 shows one of the possible applications of the universal selector - the choice of font and text size for all elements of the document.

Example 14.1. Using the universal selector

HTML5CSS 2.1IECrOpSaFx 

<!DOCTYPE HTML> <html> <head> <meta charset="utf-8"> <title>Универсальный селектор</title> <style> * { font-family: Arial, Verdana, sans-serif; /* Рубленый шрифт для текста */ font-size: 96%; /* Размер текста */ } </style> </head> <body> <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diem nonummy nibh euismod tincidunt ut lacreet dolore magna aliguam erat volutpat.</p> </body> </html>


Note that a similar result can be obtained if in this example you change the selector * to BODY.
