In HTML, most attributes have two faces: the content attribute and the IDL attribute.
The content attribute is the attribute as you set it from the content (the HTML code) and you can set it or get it via element.setAttribute() or element.getAttribute(). The content attribute is always a string even when the expected value should be an integer. For example, to set an element's maxlength to 42 using the content attribute, you have to call setAttribute("maxlength", "42") on that element.
The IDL attribute is also known as a JavaScript property. These are
the attributes you can read or set using JavaScript properties like element.foo.
The IDL attribute is always going to use (but might transform) the
underlying content attribute to return a value when you get it and is
going to save something in the content attribute when you set it. In
other words, the IDL attributes, in essence, reflect the content
attributes.
Most of the time, IDL attributes will return their valules as they are really used. For example, the default type for elements is "text", so if you set input.type="foobar", the
element will be of type text (in the appearance and the behavior) but
the "type" content attribute's value will be "foobar". However, the type IDL attribute will return the string "text".
IDL attributes are not always strings; for example, input.maxlength is a number (a signed long). When using IDL attributes, you read or set values of the desired type, so input.maxlength is always going to return a number and when you set input.maxlength
,it wants a number. If you pass another type, it is automatically
converted to a number as specified by the standard JavaScript rules for
type conversion.
IDL attributes can reflect other types
such as unsigned long, URLs, booleans, etc. Unfortunately, there are no
clear rules and the way IDL attributes behave in conjunction with their
corresponding content attributes depends on the attribute. Most of the
time, it will follow the rules laid out in the specification,
but sometimes it doesn't. HTML specifications try to make this as
developer-friendly as possible, but for various reasons (mostly
historical), some attributes behave oddly (select.size, for example) and you should read the specifications to understand how exactly they behave.
Global attributes are attributes common to all HTML
elements; they can be used on all elements, though the attributes may
have no effect on some elements.
Global attributes may be specified on all HTML elements, even those not specified in the standard.
That means that any non-standard elements must still permit these
attributes, even though using those elements means that the document is
no longer HTML5-compliant. For example, HTML5-compliant browsers hide
content marked as ..., even though is not a valid HTML element.
In addition to the basic HTML global attributes, the following global attributes also exist:
xml:lang and xml:base — these are inherited from the XHTML specifications and deprecated, but kept for compatibility purposes.
The multiple aria-* attributes, used for improving accessibility.
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.
Is a space-separated list of the classes of the element. Classes
allows CSS and JavaScript to select and access specific elements via the
class selectors or functions like the method Document.getElementsByClassName().
Is 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 element must be editable;
false, which indicates that the element must not be editable.
Forms a class of attributes, called custom data attributes, that allow proprietary information to be exchanged between the HTML and its DOM representation that may be used by scripts. All such custom data are available via the HTMLElement interface of the element the attribute is set on. The HTMLElement.dataset property gives access to them.
Is 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.
Is an enumerated attribute indicating what types of content can be dropped on an element, using the Drag and Drop API. 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.
Is 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).
Properties that are not descendants of an element with the itemscope attribute can be associated with the item using an itemref. Itemref provides a list of element ids (not itemids) with additional properties elsewhere in the document.
Itemscope (usually) works along with itemtype 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 schema.org) that describes the item and its properties context.
Specifies the URL of the vocabulary that will be used to define itemprop's (item properties) in the data structure. Itemscope is used to set the scope of where in the data structure the vocabulary set by itemtype will be active.
Participates in defining the language of the element, the language
that non-editable elements are written in or the language that editable
elements should be written in. The tag contains one single entry value
in the format defines in the Tags for Identifying Languages (BCP47) IETF document. xml:lang has priority over it.
Assigns a slot in a shadow DOM shadow tree to an element: An element with a slot attribute is assigned to the slot created by the element whose name attribute's value matches that slot attribute's value.
Contains CSS
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.
Is 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 keyboard navigation;
0 means that the element should be focusable and
reachable via sequential keyboard navigation, but its relative order is
defined by the platform convention;
a positive value which means should be focusable and
reachable via sequential keyboard navigation; its relative order is
defined by the value of the attribute: the sequential follow the
increasing number of the tabindex. If several elements share the same tabindex, their relative order follows their relative position 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.
Is an enumerated attribute that is used to specify whether an element's attribute values and the values of itsText
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.
Snapshot of WHATWG HTML Living Standard. From HTML 4.01 Specification, the concept of global attributes is introduced and the dir, lang, style, id, class, tabindex, accesskey, and title are now true global attributes. xml:lang which was initially part of XHTML, is now also part of HTML. hidden, data-*, contextmenu, contenteditable, and translate have been added.
There are no global attributes defined. Several attributes that
will become global attributes in subsequent specifications are defined
on a subset of elements. class and style are supported on all elements but , , , , , , , , and . dir is supported on all elements but , , , , , , , , , and . id is supported on all elements but , , , , , , and . lang is supported on all elements but , , , , , , , , and . tabindex is only supported on , , , , , and . accesskey is only supported on , , , , , and . title is supported on all elements but , , , , , , , and .
