|
|
|
|
|
|
|
The sizes HTML attribute on an C<source> element specifies different image widths. |
93
|
|
|
|
|
|
|
|
94
|
|
|
|
|
|
|
These widths are tied to browser conditions which helps create responsive images. |

123

|
|
|
|
124
|
|
|
|
|
|
|
Is a string reflecting the src L<HTML attribute|HTML::Object::DOM::Attribute>, containing the URL for the media resource. The C<src> property has a meaning only when the associated C<source> element is nested in a media element that is a L<video|HTML::Object::DOM::Element::Video> or an L<audio|HTML::Object::DOM::Element::Audio> element. It has no meaning and is ignored when it is nested in a C<picture> element. |
125
|
|
|
|
|
|
|
|
126
|
|
|
|
|
|
|
Note: If the C<src> property is updated (along with any siblings), the parent L<HTML::Object::DOM::Element::Media>'s load method should be called when done, since C<source> elements are not re-scanned automatically. |
