CSS improvements. CSS is a widely used standard for creating Web pages. Internet Explorer 7 is prioritizing compliance to CSS standards by first implementing the features that developers have said are most important to them. As a result, in Internet Explorer 7 beta 1 Microsoft has addressed some of the major inconsistencies that can cause Web developers problems producing rich, interactive Web pages. The work Microsoft has done includes fixing some positioning and layout issues related to the way Internet Explorer 6 handles <div> tags. (More information about these bugs can be found online at http://www.positioniseverything.net/.../peekaboo.html and http://www.positioniseverything.net/...uillotine.html. The final release of Internet Explorer 7 will focus on improving the developer experience by reducing the time needed for developing and testing on different browsers.

Hoffen wir mal, dass der Browser hält, was hier versprochen wird.
