Describes how to customize a standard Web Part in SharePoint by using SharePoint Designer 2010. Depending of the look and feel such as accessibility, performance or cross browser stability it could be a challenge to bend the web part UI exactly in the way you want. The markup of the web parts in SharePoint contains quite a deep nested table structure and the elements do not always have an id or class. 

Download the images and put them into Images library or change the path in the CSS below if you want to put the images in some other folder.
