It appears to be a graphics-intensive page, yet the actual content is less than 2 KB of text, and the elements animate smoothly in 3D under user control. Elements can be positioned, rotated, and scaled in 2D and 3D space perspective can also be applied, giving elements the appearance of depth.įor example, Figure 7-1 shows a simple HTML document, containing only div elements and text but rendered using CSS transform and gradient properties. (2014).Use CSS transform properties to give webpages a rich visual appearance without needing image files.
