src
track - Address of the track (.vtt
file). Must be a valid URL. This attribute must be defined.
source - Required for <audio>
and <video>
, address of the media resource. The value of this attribute is ignored when the <source>
element is placed inside a <picture>
element.
video - The URL of the video to embed. This is optional; you may instead use the <source>
element within the video block to specify the video to embed.
audio - The URL of the audio to embed. This is subject to HTTP access controls. This is optional; you may instead use the <source>
element within the audio block to specify the audio to embed.
img - The image URL. This attribute is mandatory for the <img>
element. On browsers supporting srcset
, src
is treated like a candidate image with a pixel density descriptor 1x
unless an image with this pixel density descriptor is already defined in srcset,
or unless srcset
contains 'w
' descriptors.
input - If the value of the type attribute is image
, this attribute specifies a URI for the location of an image to display on the graphical submit button, otherwise it is ignored.
iframe - The URL of the page to embed. Use 'about:blank' for empty pages that conform to Same-Origin Policy.
embed - The URL of the resource being embedded.
script - This attribute specifies the URI of an external script; this can be used as an alternative to embedding a script directly within a document. If a script
element has a src
attribute specified, it should not have a script embedded inside its tags.
