How to Add Style to Text in DOCX

  1. Download and install the IronWord C# library
  2. Create a new Word document or load an existing file
  3. Specify the desired font family usingFontFamily
  4. Apply bold or italic formatting to highlight selected text content
  5. Save and export the updated document with the applied style changes

Adding Text Style Example

Applying text styles in IronWord is straightforward. Create a WordDocument object, then create a TextContent object with your text. Apply a TextStyle to it using properties such as IsBold, Color, or TextFont, and enhance the styling further with options like underline or strikethrough.

Once the text is fully styled, add it to a Paragraph, insert the paragraph into the document, and save the final result.

:path=/static-assets/word/content-code-examples/how-to/add-style-text-simple.cs
using IronWord;

// Load docx
WordDocument doc = new WordDocument("sample.docx");

// Configure text
TextContent text = new TextContent();
text.Text = "Add text using IronWord";

// Configure text style settings
text.Style = new TextStyle()
{
    TextFont = new Font()
    {
        FontFamily = "Calibri", // Text Font is "Calibri"
        FontSize = 24, // Text Size is 24
    },
    Color = Color.Red, // Set text color to red
    IsBold = true,     // Make text bold
    IsItalic = true,   // Make text italic
	Underline = new Underline(), // Have an underline
    Strike = StrikeValue.DoubleStrike, // No strike-through
};

Paragraph paragraph = new Paragraph();

// Add text to paragraph
paragraph.AddText(text);

// Add paragraph to document
doc.AddParagraph(paragraph);

// Save document
doc.SaveAs("add-text-style.docx");

Adding Specific Styles

Text Color

The Color property in TextStyle allows you to set text color using predefined colors from IronWord.Models.Color or custom hex values. This is useful for emphasizing specific content or matching brand colors in your documents.

:path=/static-assets/word/content-code-examples/how-to/add-style-text-add-text.cs
using IronWord;

// Create document
WordDocument doc = new WordDocument();

// Add colored text
TextContent text = new TextContent("This text is olive-colored!");
text.Style = new TextStyle()
{
    Color = IronWord.Models.Color.Olive // defining text to be colored olive
};

Paragraph paragraph = new Paragraph();
paragraph.AddText(text);
doc.AddParagraph(paragraph);

// Save document
doc.SaveAs("colored-text.docx");

Font Family and Size

Customize text appearance with the TextFont property. Set FontFamily to any installed font name (e.g., "Arial", "Times New Roman") and FontSize in points. This allows you to match document styles or establish a clear visual hierarchy.

:path=/static-assets/word/content-code-examples/how-to/add-style-text-add-font.cs
using IronWord;

// Create document
WordDocument doc = new WordDocument();

// Add text with custom font family and size
TextContent text = new TextContent("This text uses Arial at 24pt!");
text.Style = new TextStyle()
{
    TextFont = new IronWord.Models.Font()
    {
        FontFamily = "Arial",  // Set font family
        FontSize = 24          // Set font size in points
    }
};

Paragraph paragraph = new Paragraph();
paragraph.AddText(text);
doc.AddParagraph(paragraph);

// Save document
doc.SaveAs("font-styled-text.docx");
