Although there is no perfect browser that seamlessly adheres to all standards at the time being, huge advancement has been made by several major web browsers (such as Mozilla Firefox and Opera) in the past few years that will ensure better interoperability in the future.

Current use of the term "standards-compliance" generally refers to the adherence to coding practices in relation to the use of HTML or XHTML, with Cascading Style Sheets (CSS) to define the layout, colors, and fonts of a web page. The Web Standards Project (WaSP) is a group, mainly composed of experienced web developers, whose mission is to encourage the use of these standards globally. Their recent efforts have been to promote the use of and adherence to the CSS 2.0 web standard by browsers, including how browsers respond to invalid markup and styles. The tests developed by WaSP are called Acid1, Acid2, and Acid3, with each testing CSS1, CSS2, and CSS2+ (CSS2 + Client-Side Scripting), respectively.
