HTML 能够赋予元素含义和语境。下面的可用于任何
元素。HTML 5 全局属性NEW：HTML 5 中新的全局属性。属性
描述accesskey
规定访问元素的键盘快捷键class
规定元素的类名（用于规定样式表中的类）。contenteditable
规定是否允许用户编辑内容。contextmenu
规定元素的上下文菜单。dir

&h2&可编辑列表&/h2&
&ul contenteditable&
designMode
hidden(Boolean)
&h2&不可见列表&/h2&

HTML全局属性(global attribute)有哪些?
参考资料：MDN: html global attribute或者W3C HTML global-attributes
accesskey:设置快捷键，提供快速访问元素如aaa在windows下的firefox中按alt + shift + a可激活元素
class:为元素设置类标识，多个类名用空格分开，CSS和javascript可通过class属性获取元素 contenteditable:
指定元素内容是否可编辑 contextmenu: 自定义鼠标右键弹出菜单内容 data-*: 为元素增加自定义属性 dir: 设置元素文本方向
draggable: 设置元素是否可拖拽 dropzone: 设置元素拖放类型： copy, move, link hidden:
表示一个元素是否与文档。样式上会导致元素不显示，但是不能用这个属性实现样式效果 id: 元素id，文档内唯一 lang: 元素内容的的语言
spellcheck: 是否启动拼写和语法检查 style: 行内css样式 tabindex: 设置元素可以获得焦点，通过tab可以导航
title: 元素相关的建议信息 translate: 元素和子孙节点内容是否需要本地化

扫一扫，把题目装进口袋全局属性是所有HTML元素共有的属性; 它们可以用于所有元素，即使属性可能对某些元素不起作用。
我们可以在所有的HTML元素上指定全局属性，甚至是在标准里没有指定的元素。这意味着任何非标准元素仍必须应用这些属性，即使使用这些元素意味着文档不再是html5兼容的。例如，虽然&foo&不是一个有效的HTML元素，但是html5兼容的浏览器隐藏了标记为&foo hidden&...&foo&的内容。
除了基本的HTML全局属性之外，还存在以下全局属性:
xml:lang 和 xml:base ——两者都是从XHTML规范继承，但为了兼容性而被保留的。
多重属性，用于改善可访问性。
事件处理程序属性：onabort, onautocomplete, onautocompleteerror, onblur, oncancel, oncanplay, oncanplaythrough, onchange, onclick, onclose, oncontextmenu, oncuechange, ondblclick, ondrag, ondragend, ondragenter, ondragexit, ondragleave, ondragover, ondragstart, ondrop, ondurationchange, onemptied, onended, onerror, onfocus, oninput, oninvalid, onkeydown, onkeypress, onkeyup, onload, onloadeddata, onloadedmetadata, onloadstart, onmousedown, onmouseenter, onmouseleave, onmousemove, onmouseout, onmouseover, onmouseup, onmousewheel, onpause, onplay, onplaying, onprogress, onratechange, onreset, onresize, onscroll, onseeked, onseeking, onselect, onshow, onsort, onstalled, onsubmit, onsuspend, ontimeupdate, ontoggle, onvolumechange, onwaiting.
全局属性列表
Provides a hint for generating a keyboard shortcut for the current element. This attribute consists of a space-separated list of characters. The browser should use the first one that exists on the computer keyboard layout.
Controls whether and how text input is automatically capitalized as it is entered/edited by the user. It can have the following values:
off or none, no autocapitalization is applied (all letters default to lowercase)
on or sentences, the first letter of each sentence defaults all other letters default to lowercase
words, the first letter of each word defaults all other letters default to lowercase
characters, all letters should default to uppercase
A space-separated list of the classes of the element. Classes allows CSS and JavaScript to select and access specific elements via the
or functions like the method .
An enumerated attribute indicating if the element should be editable by the user. If so, the browser modifies its widget to allow editing. The attribute must take one of the following values:
true or the empty string, which indicates that the elem
false, which indicates that the element must not be editable.
to use as the contextual menu for this element.
Forms a class of attributes, called custom data attributes, that allow proprietary information to be exchanged between the
representation that may be used by scripts. All such custom data are available via the
interface of the element the attribute is set on. The
property gives access to them.
An enumerated attribute indicating the directionality of the element's text. It can have the following values:
ltr, which means left to right and is to be used for languages that are written from the left to the right (like English);
rtl, which means right to left and is to be used for languages that are written from the right to the left (like Arabic);
auto, which let the user agent decides. It uses a basic algorithm as it parses the characters inside the element until it finds a character with a strong directionality, then apply that directionality to the whole element.
An enumerated attribute indicating whether the element can be dragged, using the . It can have the following values:
true, which indicates that the element may be dragged
false, which indicates that the element may not be dragged.
An enumerated attribute indicating what types of content can be dropped on an element, using the . It can have the following values:
copy, which indicates that dropping will create a copy of the element that was dragged
move, which indicates that the element that was dragged will be moved to this new location.
link, will create a link to the dragged data.
A Boolean attribute indicates that the element is not yet, or is no longer, relevant. For example, it can be used to hide elements of the page that can't be used until the login process has been completed. The browser won't render such elements. This attribute must not be used to hide content that could legitimately be shown.
Defines a unique identifier (ID) which must be unique in the whole document. Its purpose is to identify the element when linking (using a fragment identifier), scripting, or styling (with CSS).
Allows you to specify that a standard HTML element should behave like a registered custom built-in element (see
for more details).
Note: The item* attributes are part of the .
The unique, global identifier of an item.
Used to add properties to an item. Every HTML element may have an itemprop attribute specified, where an itemprop consists of a name and value pair.
Properties that are not descendants of an element with the itemscope attribute can be associated with the item using an itemref. It provides a list of element ids (not itemids) with additional properties elsewhere in the document.
itemscope (usually) works along with
to specify that the HTML contained in a block is about a particular item. itemscope creates the Item and defines the scope of the itemtype associated with it. itemtype is a valid URL of a vocabulary (such as ) that describes the item and its properties context.
Specifies the URL of the vocabulary that will be used to define itemprops (item properties) in the data structure.
is used to set the scope of where in the data structure the vocabulary set by itemtype will be active.
Helps define the language of an element: the language that non-editable elements are in, or the language that editable elements should be written in by the user. The attribute contains one “language tag” (made of hyphen-separated “language subtags”) in the format defined in .
has priority over it.
Assigns a slot in a
shadow tree to an element: An element with a slot attribute is assigned to the slot created by the
element whose
attribute's value matches that slot attribute's value.
An enumerated attribute defines whether the element may be checked for spelling errors. It may have the following values:
true, which indicates that the element should be, if possible, checked
false, which indicates that the element should not be checked for spelling errors.
styling declarations to be applied to the element. Note that it is recommended for styles to be defined in a separate file or files. This attribute and the
element have mainly the purpose of allowing for quick styling, for example for testing purposes.
An integer attribute indicating if the element can take input focus (is focusable), if it should participate to sequential keyboard navigation, and if so, at what position. It can takes several values:
a negative value means that the element should be focusable, but should not be reachable via sequential
0 means that the element should be focusable and reachable via sequential keyboard navigation, but its relative order is defined by the
a positive value means that the element should be focusable and reachable via sequential the order in which the elements are focused is the increasing value of the . If several elements share the same tabindex, their relative order follows their relative positions in the document.
Contains a text representing advisory information related to the element it belongs to. Such information can typically, but not necessarily, be presented to the user as a tooltip.
An enumerated attribute that is used to specify whether an element's attribute values and the values of its
node children are to be translated when the page is localized, or whether to leave them unchanged. It can have the following values:
empty string and "yes", which indicates that the element will be translated.
"no", which indicates that the element will not be translated.
