The FontSize property in the BaseStyles class represents the font-size CSS property. It allows you to specify the size of the font for a UI element. This property is of type System.Nullable<Sandbox.UI.Length>, meaning it can hold a value of type Sandbox.UI.Length or be null if the font size is not explicitly set.
To use the FontSize property, you can set it to a specific Length value, such as pixels, ems, or percentages, depending on your design requirements. If you do not set this property, the default font size will be used.
BaseStyles styles = new BaseStyles(); styles.FontSize = new Length(16, LengthUnit.Pixel); // Sets the font size to 16 pixels // Alternatively, using a nullable type styles.FontSize = null; // Resets to default font size
