4.8 Embedded content

4.8.1 The picture element

Categories:

Flow content.

Phrasing content.

Embedded content.

Palpable content.

Contexts in which this element can be used:

Where embedded content is expected.

Content model:

Zero or more source elements, followed by one img element, optionally intermixed with script-supporting elements.

Content attributes:

Global attributes

Accessibility considerations:

For authors.

For implementers.

DOM interface:

[Exposed=Window]
interface HTMLPictureElement : HTMLElement {
  [HTMLConstructor] constructor();
};

The picture element is a container which provides multiple sources to its contained img element to allow authors to declaratively control or give hints to the user agent about which image resource to use, based on the screen pixel density, viewport size, image format, and other factors. It represents its children.

The picture element is somewhat different from the similar-looking video and audio elements. While all of them contain source elements, the source element's src attribute has no meaning when the element is nested within a picture element, and the resource selection algorithm is different. Also, the picture element itself does not display anything; it merely provides a context for its contained img element that enables it to choose from multiple URLs.

4.8.2 The source element

Categories:

None.

Contexts in which this element can be used:

As a child of a picture element, before the img element.

As a child of a media element, before any flow content or track elements.

Content model:

Nothing.

Content attributes:

Global attributes

type

media

src (in audio or video)

srcset (in picture)

sizes (in picture)

width (in picture)

height (in picture)

Accessibility considerations:

For authors.

For implementers.

DOM interface:

[Exposed=Window]
interface HTMLSourceElement : HTMLElement {
  [HTMLConstructor] constructor();

  [CEReactions] attribute USVString src;
  [CEReactions] attribute DOMString type;
  [CEReactions] attribute USVString srcset;
  [CEReactions] attribute DOMString sizes;
  [CEReactions] attribute DOMString media;
  [CEReactions] attribute unsigned long width;
  [CEReactions] attribute unsigned long height;
};

The source element allows authors to specify multiple alternative source sets for img elements or multiple alternative media resources for media elements. It does not represent anything on its own.

The type attribute may be present. If present, the value must be a valid MIME type string.

The media attribute may also be present. If present, the value must contain a valid media query list. The user agent will skip to the next source element if the value does not match the environment.

The media attribute is only evaluated once during the resource selection algorithm for media elements. In contrast, when using the picture element, the user agent will react to changes in the environment.

The remainder of the requirements depend on whether the parent is a picture element or a media element:

The source element's parent is a picture element

The srcset attribute must be present, and is a srcset attribute.

The srcset attribute contributes the image sources to the source set, if the source element is selected.

If the srcset attribute has any image candidate strings using a width descriptor, the sizes attribute may also be present. If, additionally, the following sibling img element does not allow auto-sizes, the sizes attribute must be present. The sizes attribute is a sizes attribute, which contributes the source size to the source set, if the source element is selected.

If the img element allows auto-sizes, then the sizes attribute can be omitted on previous sibling source elements. In such cases, it is equivalent to specifying auto.

The source element supports dimension attributes. The img element can use the width and height attributes of a source element, instead of those on the img element itself, to determine its rendered dimensions and aspect-ratio, as defined in the Rendering section.

The type attribute gives the type of the images in the source set, to allow the user agent to skip to the next source element if it does not support the given type.

If the type attribute is not specified, the user agent will not select a different source element if it finds that it does not support the image format after fetching it.

When a source element has a following sibling source element or img element with a srcset attribute specified, it must have at least one of the following:

• A media attribute specified with a value that, after stripping leading and trailing ASCII whitespace, is not the empty string and is not an ASCII case-insensitive match for the string "all".

• A type attribute specified.

The src attribute must not be present.

The source element's parent is a media element

The src attribute gives the URL of the media resource. The value must be a valid non-empty URL potentially surrounded by spaces. This attribute must be present.

The type attribute gives the type of the media resource, to help the user agent determine if it can play this media resource before fetching it. The codecs parameter, which certain MIME types define, might be necessary to specify exactly how the resource is encoded. [RFC6381]

Dynamically modifying a source element's src or type attribute when the element is already inserted in a video or audio element will have no effect. To change what is playing, just use the src attribute on the media element directly, possibly making use of the canPlayType() method to pick from amongst available resources. Generally, manipulating source elements manually after the document has been parsed is an unnecessarily complicated approach.

The following list shows some examples of how to use the codecs= MIME parameter in the type attribute.

The srcset and sizes attributes must not be present.

The source HTML element insertion steps, given insertedNode, are:

1. If insertedNode's parent is a media element that has no src attribute and whose networkState has the value NETWORK_EMPTY, then invoke that media element's resource selection algorithm.

2. If insertedNode's next sibling is an img element and its parent is a picture element, then, count this as a relevant mutation for the img element.

The source HTML element removing steps, given removedNode and oldParent, are:

1. If removedNode's next sibling was an img element and oldParent is a picture element, then, count this as a relevant mutation for the img element.

The IDL attributes src, type, srcset, sizes and media must reflect the respective content attributes of the same name.

<script>
 function fallback(video) {
   // replace <video> with its contents
   while (video.hasChildNodes()) {
     if (video.firstChild instanceof HTMLSourceElement)

     else
       video.parentNode.insertBefore(video.firstChild, video);
   }
   video.parentNode.removeChild(video);

An img element represents an image.

An img element has a dimension attribute source, initially set to the element itself.

The image given by the src and srcset attributes, and any previous sibling source elements' srcset attributes if the parent is a picture element, is the embedded content; the value of the alt attribute provides equivalent content for those who cannot process images or who have image loading disabled (i.e. it is the img element's fallback content).

The requirements on the alt attribute's value are described in a separate section.

The src attribute must be present, and must contain a valid non-empty URL potentially surrounded by spaces referencing a non-interactive, optionally animated, image resource that is neither paged nor scripted.

The requirements above imply that images can be static bitmaps (e.g. PNGs, GIFs, JPEGs), single-page vector documents (single-page PDFs, XML files with an SVG document element), animated bitmaps (APNGs, animated GIFs), animated vector graphics (XML files with an SVG document element that use declarative SMIL animation), and so forth. However, these definitions preclude SVG files with script, multipage PDF files, interactive MNG files, HTML documents, plain text documents, and the like. [PNG] [GIF] [JPEG] [PDF] [XML] [APNG] [SVG] [MNG]

The srcset attribute may also be present, and is a srcset attribute.

The srcset attribute and the src attribute (if width descriptors are not used) contribute the image sources to the source set (if no source element was selected).

If the srcset attribute is present and has any image candidate strings using a width descriptor, the sizes attribute must also be present. If the srcset attribute is not specified, and the loading attribute is in the Lazy state, the sizes attribute may be specified with the value "auto" (ASCII case-insensitive). The sizes attribute is a sizes attribute, which contributes the source size to the source set (if no source element was selected).

An img element allows auto-sizes if:

• its loading attribute is in the Lazy state, and
• its sizes attribute's value is "auto" (ASCII case-insensitive), or starts with "auto," (ASCII case-insensitive).

The crossorigin attribute is a CORS settings attribute. Its purpose is to allow images from third-party sites that allow cross-origin access to be used with canvas.

The referrerpolicy attribute is a referrer policy attribute. Its purpose is to set the referrer policy used when fetching the image. [REFERRERPOLICY]

The decoding attribute indicates the preferred method to decode this image. The attribute, if present, must be an image decoding hint. This attribute's missing value default and invalid value default are both the auto state.

The fetchpriority attribute is a fetch priority attribute. Its purpose is to set the priority used when fetching the image.

The loading attribute is a lazy loading attribute. Its purpose is to indicate the policy for loading images that are outside the viewport.

When the loading attribute's state is changed to the Eager state, the user agent must run these steps:

1. Let resumptionSteps be the img element's lazy load resumption steps.

2. If resumptionSteps is null, then return.

3. Set the img's lazy load resumption steps to null.

4. Invoke resumptionSteps.

<img src="1.jpeg" alt="1">
<img src="2.jpeg" loading=eager alt="2">
<img src="3.jpeg" loading=lazy alt="3">
<div id=very-large></div> <!-- Everything after this div is below the viewport -->
<img src="4.jpeg" alt="4">
<img src="5.jpeg" loading=lazy alt="5">

The img HTML element insertion steps, given insertedNode, are:

1. If insertedNode's parent is a picture element, then, count this as a relevant mutation for insertedNode.

The img HTML element removing steps, given removedNode and oldParent, are:

1. If oldParent is a picture element, then, count this as a relevant mutation for removedNode.

The img element must not be used as a layout tool. In particular, img elements should not be used to display transparent images, as such images rarely convey meaning and rarely add anything useful to the document.

What an img element represents depends on the src attribute and the alt attribute.

If the src attribute is set and the alt attribute is set to the empty string

The image is either decorative or supplemental to the rest of the content, redundant with some other information in the document.

If the image is available and the user agent is configured to display that image, then the element represents the element's image data.

Otherwise, the element represents nothing, and may be omitted completely from the rendering. User agents may provide the user with a notification that an image is present but has been omitted from the rendering.

If the src attribute is set and the alt attribute is set to a value that isn't empty

The image is a key part of the content; the alt attribute gives a textual equivalent or replacement for the image.

If the image is available and the user agent is configured to display that image, then the element represents the element's image data.

Otherwise, the element represents the text given by the alt attribute. User agents may provide the user with a notification that an image is present but has been omitted from the rendering.

If the src attribute is set and the alt attribute is not

The image might be a key part of the content, and there is no textual equivalent of the image available.

In a conforming document, the absence of the alt attribute indicates that the image is a key part of the content but that a textual replacement for the image was not available when the image was generated.

If the image is available and the user agent is configured to display that image, then the element represents the element's image data.

If the image has a src attribute whose value is the empty string, then the element represents nothing.

Otherwise, the user agent should display some sort of indicator that there is an image that is not being rendered, and may, if requested by the user, or if so configured, or when required to provide contextual information in response to navigation, provide caption information for the image, derived as follows:

1. If the image has a title attribute whose value is not the empty string, then return the value of that attribute.

2. If the image is a descendant of a figure element that has a child figcaption element, and, ignoring the figcaption element and its descendants, the figure element has no flow content descendants other than inter-element whitespace and the img element, then return the contents of the first such figcaption element.

3. Return nothing. (There is no caption information.)

If the src attribute is not set and either the alt attribute is set to the empty string or the alt attribute is not set at all

The element represents nothing.

Otherwise

The element represents the text given by the alt attribute.

The alt attribute does not represent advisory information. User agents must not present the contents of the alt attribute in the same way as content of the title attribute.

User agents may always provide the user with the option to display any image, or to prevent any image from being displayed. User agents may also apply heuristics to help the user make use of the image when the user is unable to see it, e.g. due to a visual disability or because they are using a text terminal with no graphics capabilities. Such heuristics could include, for instance, optical character recognition (OCR) of text found within the image.

While user agents are encouraged to repair cases of missing alt attributes, authors must not rely on such behavior. Requirements for providing text to act as an alternative for images are described in detail below.

The contents of img elements, if any, are ignored for the purposes of rendering.

The usemap attribute, if present, can indicate that the image has an associated image map.

The ismap attribute, when used on an element that is a descendant of an a element with an href attribute, indicates by its presence that the element provides access to a server-side image map. This affects how events are handled on the corresponding a element.

The ismap attribute is a boolean attribute. The attribute must not be specified on an element that does not have an ancestor a element with an href attribute.

The usemap and ismap attributes can result in confusing behavior when used together with source elements with the media attribute specified in a picture element.

The img element supports dimension attributes.

The alt, src, srcset and sizes IDL attributes must reflect the respective content attributes of the same name.

The crossOrigin IDL attribute must reflect the crossorigin content attribute, limited to only known values.

The useMap IDL attribute must reflect the usemap content attribute.

The isMap IDL attribute must reflect the ismap content attribute.

The referrerPolicy IDL attribute must reflect the referrerpolicy content attribute, limited to only known values.

The decoding IDL attribute must reflect the decoding content attribute, limited to only known values.

The loading IDL attribute must reflect the loading content attribute, limited to only known values.

The fetchPriority IDL attribute must reflect the fetchpriority content attribute, limited to only known values.

Returns a new img element, with the width and height attributes set to the values passed in the relevant arguments, if applicable.

The IDL attributes width and height must return the rendered width and height of the image, in CSS pixels, if the image is being rendered; or else the density-corrected natural width and height of the image, in CSS pixels, if the image has density-corrected natural width and height and is available but is not being rendered; or else 0, if the image is not available or does not have density-corrected natural width and height. [CSS]

On setting, they must act as if they reflected the respective content attributes of the same name.

The IDL attributes naturalWidth and naturalHeight must return the density-corrected natural width and height of the image, in CSS pixels, if the image has density-corrected natural width and height and is available, or else 0. [CSS]

Since the density-corrected natural width and height of an image take into account any orientation specified in its metadata, naturalWidth and naturalHeight reflect the dimensions after applying any rotation needed to correctly orient the image, regardless of the value of the 'image-orientation' property.

The complete getter steps are:

1. If any of the following are true:

   • both the src attribute and the srcset attribute are omitted;

   • the srcset attribute is omitted and the src attribute's value is the empty string;

   • the img element's current request's state is completely available and its pending request is null; or

   • the img element's current request's state is broken and its pending request is null,

   then return true.

2. Return false.

The currentSrc IDL attribute must return the img element's current request's current URL.

The decode() method, when invoked, must perform the following steps:

1. Let promise be a new promise.

2. Queue a microtask to perform the following steps:

   This is done because updating the image data takes place in a microtask as well. Thus, to make code such as

   img.src = "stars.jpg";
   img.decode();

   properly decode stars.jpg, we need to delay any processing by one microtask.

   1. If any of the following are true:

      • this's node document is not fully active; or

      • this's current request's state is broken,

      then reject promise with an "EncodingError" DOMException.

   2. Otherwise, in parallel, wait for one of the following cases to occur, and perform the corresponding actions:

      This img element's node document stops being fully active

      This img element's current request changes or is mutated

      This img element's current request's state becomes broken

      Reject promise with an "EncodingError" DOMException.

      This img element's current request's state becomes completely available

      Decode the image.

      If decoding does not need to be performed for this image (for example because it is a vector graphic), resolve promise with undefined.

      If decoding fails (for example due to invalid image data), reject promise with an "EncodingError" DOMException.

      If the decoding process completes successfully, resolve promise with undefined.

      User agents should ensure that the decoded media data stays readily available until at least the end of the next successful update the rendering step in the event loop. This is an important part of the API contract, and should not be broken if at all possible. (Typically, this would only be violated in low-memory situations that require evicting decoded image data, or when the image is too large to keep in decoded form for this period of time.)

      Animated images will become completely available only after all their frames are loaded. Thus, even though an implementation could decode the first frame before that point, the above steps will not do so, instead waiting until all frames are available.

3. Return promise.

const img = new Image();
img.src = "nebula.jpg";
img.onload = () => {
    document.body.appendChild(img);
};
img.onerror = () => {
    document.body.appendChild(new Text("Could not load the nebula :("));
};

const img = new Image();
img.src = "nebula.jpg";
img.decode().then(() => {
    document.body.appendChild(img);
}).catch(() => {
    document.body.appendChild(new Text("Could not load the nebula :("));
});

const container = document.querySelector("#container");

const { containerWidth, containerHeight } = computeDesiredSize();
requestAnimationFrame(() => {
 container.style.width = containerWidth;
 container.style.height = containerHeight;
});

// ...

const img = new Image();
img.src = "supernova.jpg";
img.decode().then(() => {
    requestAnimationFrame(() => container.appendChild(img));
});

A legacy factory function is provided for creating HTMLImageElement objects (in addition to the factory methods from DOM such as createElement()): Image(width, height). When invoked, the legacy factory function must perform the following steps:

1. Let document be the current global object's associated Document.

2. Let img be the result of creating an element given document, img, and the HTML namespace.

3. If width is given, then set an attribute value for img using "width" and width.

4. If height is given, then set an attribute value for img using "height" and height.

5. Return img.
