Images:

• You can specify the dimensions of images using CSS. This is very helpful when you use the same sized images on several pages of your site.
• Images can be aligned both horizontally and vertically using CSS.
• You can use a background image behind the box created by any element on a page.
• Background images can appear just once or be repeated across the background of the box.
• You can create image rollover effects by moving the background position of an image.
• To reduce the number of images your browser has to load, you can create image sprites

HTML5 comes with elements for embedding rich media in documents — <video> and <audio> — which in turn come with their own APIs for controlling playback, seeking, etc.
