'''Accelerated Mobile Pages''' (AMP) are a variant of [[HTML]] promoted by Google (along with some other companies) as a way of enabling publishers to produce mobile web pages that load and render quickly and are easy to read and navigate on portable devices.

AMP documents are built with a limited subset of HTML, augmented with some AMP-specific tags to handle graphics and multimedia content. Among these specialized tags is a tag specifically for embedded ads (<code>amp-ad</code>), replacing the hodgepodge of bulky and messy scripts usually used for this purpose. Images use <code>amp-img</code> instead of the normal <code>img</code> tag, but the pages still work (images and all) in normal browsers (both mobile and desktop) because the referenced AMP script (the only permitted JavaScript in AMP documents besides a strictly-limited use of service-specific scripts) handles these special tags.

== Headers ==

AMP pages have a normal HTML 5 doctype, <code><!doctype html></code>, so they are not distinguished from normal HTML this way. However, the main <code>html</code> element has a special tag, <code><html ⚡></code>, featuring the [[Unicode]] character U+26A1, "HIGH VOLTAGE SIGN". This is a departure from usual markup-language conventions where non-[[ASCII]] characters are avoided in markup syntax (even if they are present in the text content) to avoid the various character-encoding problems that often result from their use; they are apparently presuming that everybody has "gone native" with [[UTF-8]] and can handle a wider character repertoire. However, you are allowed to use <code><html amp></code> if you don't want to use non-ASCII characters or have no idea how to type that lightning-bolt thingy (though you can copy-and-paste it from another place, including this page).
