The BorderImageWidthBottom property in the Sandbox.UI.BaseStyles class represents the border-image-width-bottom CSS property. This property allows you to specify the width of the bottom border image of an element. It is a nullable property of type Sandbox.UI.Length, which means it can hold a length value or be set to null if the property is not defined.
To use the BorderImageWidthBottom property, you can set it to a specific length value using the Sandbox.UI.Length type. This can be done in your UI component's style configuration. If you do not want to specify a bottom border image width, you can leave it as null.
// Example of setting the BorderImageWidthBottom property var styles = new BaseStyles(); styles.BorderImageWidthBottom = new Length(5, LengthUnit.Pixel); // Sets the bottom border image width to 5 pixels // Example of leaving the BorderImageWidthBottom property unset styles.BorderImageWidthBottom = null; // No specific bottom border image width is defined
