* 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.

| | | | | 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.

* Add support for CSS3 overflow-x and overflow-y properties.Michael Drake2014-06-012-4/+8
| | | | | | | | Now, overflow is a shorthand property setting both overflow-x and overflow-y. The getter for the computed overflow has been removed, and replaced with two for overflow-x and overflow-y.
* Various changes which modify API and ABI:Michael Drake2013-12-136-222/+65
| | | | | | | | | - Remove client allocation function. - Change node_classes callback not to yield array ownership to libcss. - Node bloom filters now built by, during selection libcss. - Added selection callbacks to get and set data on document nodes. Test suite, example, and documentation updated to match.
* Significantly optimise CSS selection performance.Michael Drake2013-12-012-0/+3
| | | | | | | | | | | | | | | | Now we pass a node bloom filter to css_get_style. That node bloom filter is filled with the node's ancestor element, class, and id names. Internally, libcss also generates a bloom filter for each selector chain. If the selector chain's bloom filter is not a subset of the node bloom filter, we know that the selector chain's rule does not apply to the node. This avoids the slow selector chain matching process. Other smaller optimisations to move the ruling out of selector chains for inapplicable media types and other reasons to before we start comparing rules from different sources to find the next rule. All this is now done in hash.c so select.c never sees the trivially ruled out rules.
