Struct moxie_dom::elements::embedding::SourceBuilder [−][src]
pub struct SourceBuilder { /* fields omitted */ }Expand description
The HTML <source> element specifies multiple media resources for the
<picture>, the <audio> element, or the <video> element.
A type for initializing the element’s attributes before calling build.
Implementations
Media query of the resource’s intended media; this should be used only in a <picture>
element.
Is a list of source sizes that describes the final rendered width of the image represented by the source. Each source size consists of a comma-separated list of media condition-length pairs. This information is used by the browser to determine, before laying the page out, which image defined in srcset to use. Please note that sizes will have its effect only if width dimension descriptors are provided with srcset instead of pixel ratio values (200w instead of 2x for example).
The sizes attribute has an effect only when the <source> element is the direct child of
a <picture> element.
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.
A list of one or more strings separated by commas indicating a set of possible images represented by the source for the browser to use. Each string is composed of:
- One URL specifying an image.
- A width descriptor, which consists of a string containing a positive integer directly followed by “w”, such as 300w. The default value, if missing, is the infinity.
- A pixel density descriptor, that is a positive floating number directly followed by “x”. The default value, if missing, is 1x.
Each string in the list must have at least a width descriptor or a pixel density descriptor to be valid. Among the list, there must be only one string containing the same tuple of width descriptor and pixel density descriptor. The browser chooses the most adequate image to display at a given point of time.
The srcset attribute has an effect only when the <source> element is the direct child of
a <picture> element.

Indicates if the element is hidden or not.
Indicates whether the user agent must act as though the given node is absent for the purposes of user interaction events, in-page text searches (“find in page”), and text selection. Read more
Provides a hint as to the type of data that might be entered by the user while editing the element or its contents. The attribute can be used with form controls (such as the value of textarea elements), or in elements in an editing host (e.g., using contenteditable attribute). Read more

Indicates whether spell checking is allowed for the element.
