=== Compatibility and restrictions ===

Because of the [[Usage share of web browsers|market share of modern browsers]] (depending on your target market), the compatibility of your website with the viewers is restricted. For instance, a website that is designed for the majority of websurfers will be limited to the use of [[W3C Markup Validation Service|valid]] [[XHTML]] 1.0 Strict or older, [[Cascading Style Sheets]] Level 1, and 1024x768 [[display resolution]]. This is because [[Internet Explorer]] is not fully [[W3C]] [[Web standards|standards compliant]] with the [[modularity]] of XHTML 1.1 and the majority of CSS beyond 1. A target market of more alternative browser (e.g. [[Firefox]], [[Safari (web browser)|Safari]] and [[Opera (web browser)|Opera]]) users allow for more W3C compliance and thus a greater range of options for a web designer.

Another restriction on webpage design is the use of different [[Image file formats]]. The majority of users can support [[Graphics Interchange Format|GIF]], [[JPEG]], and [[Portable Network Graphics|PNG]] (with restrictions). Again [[Internet Explorer]] is the major restriction here, not fully supporting PNG's advanced transparency features, resulting in the GIF format still being the most widely used graphic file format for transparent images.
