type +'a elt

HTML elements.

Element constructors are in section elements. Most elements constructors are either nullary, unary or star, depending on the number of children they accept. Children are usually given as a list of elements. txt is used for text.

div [a [txt "Foo"]] is equivalent to <div><a>foo</a></div>

The type variable 'a is used to track the element's type. This allows the OCaml typechecker to check HTML validity.

For example, div [] is of type [> `Div] elt. The span function only accepts children of type Html_types.span_content. Since `Div is not part of it. span [div []] will not typecheck.

Note that the concrete implementation of this type can vary. See Xml for details.

type doc = Html_types.html elt

A complete HTML document.

type +'a attrib

HTML attributes

Attribute constructors are in section attributes and their name starts with a_. Attributes are given to elements with the ~a optional argument.

a ~a:[a_href "ocsigen.org"] [txt "link!"] is equivalent to <a href="ocsigen.org">link!</a>

Similarly to elt, attributes use the OCaml type system to enforce HTML validity.

For example a_href returns a value of type [> `Href] attrib. The div function only accepts attributes of type Html_types.div_attrib. Since `Href is not part of it, div ~a:[a_href "ocsigen.org"] [] will not typecheck.

In some cases, attributes have to be disambiguated. The max attribute has two version, a_max and a_input_max, depending on the element. Such disambiguated attribute will contain the name of the associated element.

module Xml : Xml_sigs.T

Underlying XML data-structure

type 'a wrap = 'a Xml.W.t

wrap is a container for elements and values.

In most cases, 'a wrap = 'a. For R modules (in eliom or js_of_ocaml), It will be React.S.t.

type 'a list_wrap = 'a Xml.W.tlist

list_wrap is a container for list of elements.

In most cases, 'a list_wrap = 'a list. For R modules (in eliom or js_of_ocaml), It will be ReactiveData.RList.t.

type ('a, 'b) nullary = ?a:'a attrib list -> unit -> 'b elt

A nullary element is an element that doesn't have any children.

type ('a, 'b, 'c) unary = ?a:'a attrib list -> 'b elt wrap -> 'c elt

A unary element is an element that have exactly one children.

type ('a, 'b, 'c) star = ?a:'a attrib list -> 'b elt list_wrap -> 'c elt

A star element is an element that has any number of children, including zero.

module Svg : Svg_sigs.T with module Xml := Xml

Associated SVG module, for the svg combinator.

module Info : Xml_sigs.Info

Various information about HTML, such as the doctype, ...

Uri

type uri = Xml.uri

val string_of_uri : (uri, string) Xml.W.ft

val uri_of_string : (string, uri) Xml.W.ft

Attributes

val a_class : Html_types.nmtokens wrap -> [> `Class ] attrib

This attribute assigns a class name or set of class names to an element. Any number of elements may be assigned the same class name or names.

val a_user_data : 
  Html_types.nmtoken ->
  Html_types.text wrap ->
  [> `User_data ] attrib

May be used to specify custom attributes. The example given by the W3C is as follows :

<ol>
  <li data-length="2m11s">Beyond The Sea</li>
</ol>

It should be used for preprocessing ends only.

val a_id : Html_types.text wrap -> [> `Id ] attrib

This attribute assigns a name to an element. This name must be unique in a document. The text should be without any space.

val a_title : Html_types.text wrap -> [> `Title ] attrib

This attribute offers advisory information about the element for which it is set.

Values of the title attribute may be rendered by user agents in a variety of ways. For instance, visual browsers frequently display the title as a tool tip (a short message that appears when the pointing device pauses over an object). Audio user agents may speak the title information in a similar context.

The title attribute has an additional role when used with the link element to designate an external style sheet. Please consult the section on links and style sheets for details.

This attribute specifies the visible width in average character widths. Users should be able to enter longer lines than this, so user agents should provide some means to scroll through the contents of the control when the contents extend beyond the visible area. User agents may wrap visible text lines to keep long lines visible without the need for scrolling.

ARIA support

WAI-ARIA is a specification written by the W3C, defining a set of additional HTML attributes that can be applied to elements to provide additional semantics and improve accessibility wherever it is lacking.

See for example a WAI-ARIA tutorial.

val a_role : string list wrap -> [> `Role ] attrib

see https://www.w3.org/TR/role-attribute
Role attribute specification

see https://www.w3.org/TR/wai-aria-1.1/#role_definitions

val a_aria : string -> string list wrap -> [> `Aria ] attrib

Basic support for WAI-ARIA attributes: a_aria "foo" corresponds to an "aria-foo" attribute.
