Performance on the web is multi-dimensional. In this test we focus on the browser layout engine to exercise the browser's handling of CSS 2.1 and CSS 3 layout constructs. These constructs are used to style HTML, and the layout engine is an important component of overall web browser performance.
The mazes in this test are constructed from hundreds of HTML elements styled with CSS. Every step through the maze changes the style of a single HTML element. How quickly a browser can process that change determines how quickly the maze is completed. Designed from the ground up for speed, Internet Explorer 9's layout engine scales well even to large mazes.
