pub struct MediaList {
    pub media_queries: Vec<MediaQuery>,
}
Expand description

A type that encapsulates a media query list.

Fields§

§media_queries: Vec<MediaQuery>

The list of media queries.

Implementations§

source§

impl MediaList

source

pub fn parse(context: &ParserContext<'_>, input: &mut Parser<'_, '_>) -> Self

Parse a media query list from CSS.

Always returns a media query list. If any invalid media query is found, the media query list is only filled with the equivalent of “not all”, see:

https://drafts.csswg.org/mediaqueries/#error-handling

source

pub fn empty() -> Self

Create an empty MediaList.

source

pub fn evaluate(&self, device: &Device, quirks_mode: QuirksMode) -> bool

Evaluate a whole MediaList against Device.

source

pub fn is_empty(&self) -> bool

Whether this MediaList contains no media queries.

source

pub fn is_viewport_dependent(&self) -> bool

Whether this MediaList depends on the viewport size.

source

pub fn append_medium( &mut self, context: &ParserContext<'_>, new_medium: &str ) -> bool

Append a new media query item to the media list. https://drafts.csswg.org/cssom/#dom-medialist-appendmedium

Returns true if added, false if fail to parse the medium string.

source

pub fn delete_medium( &mut self, context: &ParserContext<'_>, old_medium: &str ) -> bool

Delete a media query from the media list. https://drafts.csswg.org/cssom/#dom-medialist-deletemedium

Returns true if found and deleted, false otherwise.
