# Styles

## Content



The [XLStyle](/componentone/api/wpf/online-excel/dotnet-framework-api/C1.WPF.Excel.4.6.2/C1.WPF.Excel.XLStyle.html) class defines the appearance of a cell, row, or column on a sheet. **XLStyle** includes properties that specify style elements such as the font, alignment, colors, and format used to display cell values. Not all style elements need to be defined in every **XLStyle** object. For example, if an **XLStyle** specifies only a format, then the cell is displayed using the specified format and default settings for the other style elements (font, alignment, and so on).
