The Web Standards Project, the developer group that polices adherence to World Wide Web Consortium (W3C) and other standards in web browsers, has given Opera Software’s support for cascading style sheets (CSS) a qualified thumbs up. Cascading style sheets give developers precise control over the appearance of a page that we’ve been waiting for, said George Olsen, WSP project leader and director of design at 2-Lane Media in Los Angeles. Until recently, however, browser support for CSS was uneven, making it impractical for developers to take advantage of what the standard can do. The WSP says Opera Software has made a late but commendable attempt at implementing CSS in the latest release of its Opera browser. Opera 3.50 is so far the best implementation of CSS1 by any company and arguably the best implementation released today, the group writes. However Opera’s implementation is in no way perfect, it concludes. A standards-compliance review identifies problems with width, borders, backgrounds, parsing and cascading, as well as vertical formatting and floating element bugs, as Opera’s most serious shortcomings. Also missing are the display property, alternative stylesheet UI and white-space. Some of these problems were fixed in 3.5.1, the WSP concedes, but it notes that major bugs remain.
