AngleSharp.Css extends the core AngleSharp library with some more powerful CSS capabilities. This repository is the home of the source for the AngleSharp.Css NuGet package.

Basic Configuration

If you just want a configuration that works (as close as possible to real browsers) you should use the following code:

var config = Configuration.Default
    .WithCss(); // from AngleSharp.Css

This will register a parser for CSS related content. The CSS parsing options and more could be set with parameters of the WithCss method. Alternatively, all the (desired) parts may be registered individually as well. That mostly boils down to three elementary parts:

  • A CSS parser (implementing the ICssParser interface, e.g., CssParser)
  • A factory for creating CSS declarations (IDeclarationFactory)
  • The styling service that can handle CSS documents, see CssStylingService

For an interactive DOM (i.e., to handle style attribute changes in the HTML document) an observer needs to be registered as well.

Furthermore, for some CSSOM features (e.g., media queries) a render device is required.

var config = Configuration.Default
    .WithCss()
    .WithRenderDevice(new DefaultRenderDevice
    {
        DeviceHeight = 768,
        DeviceWidth = 1024,
    });

If no specific IRenderDevice (e.g., via creating an DefaultRenderDevice object) instance is created a default implementation will be set.

Going a bit further it is possible to Render the current document. This render tree information can then be used to retrieve or other information, e.g.,

var tree = document.DefaultView.Render();
var node = tree.Find(document.QuerySelector("div"));
await node.DownloadResources();

The previous snippet renders the current document. Afterwards it retrieves a particular render tree node, which is related to the first found div. Then all (CSS introduced) resources are downloaded for the node, if visible.

Advantages of AngleSharp.Css

The core library already contains the CSS selector parser and the most basic classes and interfaces for dealing with the CSSOM. AngleSharp.Css brings the following advantages and use cases to life:

  • Correct identification of edge cases
  • A live CSSOM model, i.e., callbacks and everything
  • Computing the styling of certain elements
  • Cascades of stylesheets
  • Validation (and property-based exposure) of CSS declarations
  • Responsive design considerations
  • Full access to the value with different converters

The main idea behind AngleSharp.Css is to expose the CSSOM as it would be in the browser (and potentially beyond, i.e., useful for being used by editors). Originally, most of the code found here was embedded in the AngleSharp.Core library, however, due to the overhead for HTML use cases it was decided to transfer the code into its own repository.

Features

  • Feature validators (e.g., for @supports)
  • Document functions (e.g., for domain)
  • Pseudo elements (e.g., ::before)
  • Declarations (e.g., display) incl. knowledge of their values
  • Dynamic DOM coupling (i.e., to react to style attribute changes)
  • CSS custom properties (also known as CSS variables) with extensibility
  • Media queries and all other commonly implemented rules
  • Calculated values (i.e., calc(20px + 50%))
  • Window-based declaration calculations, see window.GetComputedStyle
