The doodle actually consists of lots of pieces of a web page, each using a modern form of web coding called CSS3 – "Cascading Style Sheet" elements. Each circle is actually an element called a "div" – an element into which the page is divided – which contains an instruction in its associated piece of CSS3 to make it circular rather than square or rectangular. The code also contains instructions so that if the cursor is moved near to any of the "bubbles", they try to move away.The aim of the logo seems to be to draw attention to the importance of CSS3, an emerging standard which is being developed as the next version of the web language HTML, called HTML5, is being ratified by the World Wide Web Consortium.Google has been eager to push HTML5 and CSS3, and its Chrome browser, because it offers many more possibilities in the design of web pages, which could be more interactive with less effort by designers. It has produced HTML5 versions of its video site YouTube so that they will be more mobile-friendly for people whose smartphones cannot cope with Adobe Flash content, usually used for video content on desktop computers.
