Where does CssToken live in the IronPDF API?

CssToken is a class in the IronPdf namespace, shipped in IronPdf.dll. It derives from Object and holds two properties: Type (a CssTokenType) and Value (a string).

How do you create and modify a CssToken in C#?

Call the constructor CssToken(CssTokenType type, string value) to create a token. Both the Type and Value properties have public setters, so you can update either field in place as your CSS processing pipeline runs.

Class CssToken

Represents a CSS token with its type and value

Inheritance

System.Object

CssToken

Namespace: IronPdf

Assembly: IronPdf.dll

Syntax

public class CssToken : Object

Parsing and inspecting CSS at a granular level becomes straightforward when each piece of a stylesheet is represented as a CssToken, a record pairing a classification with its raw text. Each token carries a Type property of kind CssTokenType that identifies the role the token plays (selector, property name, value, delimiter, and so on) alongside a Value string that holds the exact text extracted from the source. Together these two properties let downstream code branch on token kind and act on the literal content without re-parsing the stylesheet.

Construct a token directly with CssToken(CssTokenType type, string value) when building a token stream by hand, for example when writing a CSS pre-processor or injecting synthetic rules before IronPDF renders a document. Both Type and Value expose public setters, so a token can be mutated in place as a pipeline transforms it, rather than requiring a new allocation for every edit.

CssToken sits at the low level of IronPDF's CSS handling. Higher-level rendering options such as custom stylesheets and media-type overrides are configured through the main rendering API, but CssToken gives precise access to the token stream for tooling that needs to inspect or rewrite CSS before it reaches the renderer.

using IronPdf;

var token = new CssToken(CssTokenType.Value, "14px");
if (token.Type == CssTokenType.Value)
    token.Value = "16px"; // scale up base font size before rendering

See the IronPDF documentation hub for an overview of the rendering pipeline, and the custom CSS how-to for practical examples of injecting styles into a PDF render job.
