* Add support for SVG stroke-opacity propertyMichael Orlitzky2023-10-012-0/+10
| | | | | | | | https://www.w3.org/TR/SVGTiny12/painting.html#StrokeOpacityProperty This property is unique to SVG documents, but is otherwise analogous to the usual CSS "opacity" property (and the recently-added SVG fill-opacity property).

* API: Client media spec: Allow colour scheme preferenceMichael Drake2022-07-311-0/+2

* Selection: Don't duplicate unit conversion members in media descriptor.Michael Drake2021-05-194-12/+10
|
* Selection: Remove client callback for unit conversion.Michael Drake2021-05-193-7/+160
| | | | | | | Now clients provide a unit conversion context and libcss provides code to perform unit conversion. This reduces the amount of common code that clients have to write.

* Media queries: Feature matching: Compare lengths in pixels.Michael Drake2019-05-071-8/+7
| | | | | | | | Clients now provide viewport dimensions in pixels. LibCSS can now convert the units from the stylesheet to pixels. Client must also provide default font size and line height for handling viewport and root element relative sizes.
* Media queries: Update selection API to support media queries.Michael Drake2019-05-041-4/+4
| | | | | | | | | | | | | | | | | | | | | The API changes are: 1. When building a selection context, stylesheets added with `css_select_ctx_{append|insert}_sheet()` now have to have media strings associcated with them. Previously they took a simple bitfield for CSS media type. 2. When selecting for an element, the client needs to specify the current media requirements. Previously it only had to provide the bitfield for CSS media type. 3. Same for the css_select_font_faces API. The selection handling has been updated to handle the new API, however it is currently only looking at the media type when performing selection.

* Media Queries: datastructures and plumbing.John-Mark Bell2019-03-101-3/+2
| | | | | | | | | | | | | No parse implementation as yet. Selection hasn't been updated, either. One item of note in that area is that a client currently provides the media for top-level sheets being added to a selection context. This probably needs to change to providing a lwc_string containing the verbatim media query from the containing document's import mechanism. That way, the internal representation of media queries can remain opaque to clients.

* Intern partial styles.Michael Drake2016-11-192-3/+7
| | | | | Note this changes the public API. We can't compose directly over child style now, since it may be interned.

|
* After composing styles, intern the result in the style sharing arena.Michael Drake2016-11-191-2/+2
| | | | | Note this changes the API. Selection tests updated.
* Change how presentational hints are handled.Michael Drake2016-02-022-3/+4
| | | | | | | | | | | | | | | Previously, we performed normal selection from CSS sources, and then iterated over all the properties in the populated computed style. If the properties were unset or their values were not from either a UA stylesheet or user stylesheet with !important set, then we asked the client program (e.g. NetSurf) if there were any presentational hints for that node, for each such property. In the worst case this triggered N_PROPERTIES * N_NODES calls back to the client program, even for properties that can't be set via HTML attributes. The new API asks the client to supply a list of all the presentational hints that apply to the given node. For most nodes on modern documents, this is 0. Any presentational hints are applied before selection from CSS sources.
