XHTML Transitional Usage Statistics -
Websites using XHTML TransitionalThe website claims XHTML Transitional status. XHTML 1.0 Transitional is the same as HTML 4.01 Transitional, but follows XML syntax rules. It supports everything found in XHTML 1.0 Strict, but also permits the use of a number of elements and attributes that are judged presentational, in order to ease the transition from HTML 3.2 and earlier. These include center, u, strike, and applet.
Javascript Defer Usage Statistics -
Websites using Javascript DeferThe defer attribute gives a hint to the browser that the script does not create any content so the browser can optionally defer interpreting the script. This can improve performance by delaying execution of scripts until after the body content is parsed and rendered.
P3P Policy Usage Statistics -
Websites using P3P PolicyThe Platform for Privacy Preferences Project (P3P) enables Websites to express their privacy practices in a standard format that can be retrieved automatically and interpreted easily by user agents. P3P user agents will allow users to be informed of site practices (in both machine- and human-readable formats) and to automate decision-making based on these practices when appropriate. Thus users need not read the privacy policies at every site they visit.
