The BackgroundPositionX property in the Sandbox.UI.BaseStyles class represents the background-position-x CSS property. This property is used to set the horizontal position of a background image within an element. It can be specified using various units such as pixels, percentages, or other length units defined in the Sandbox.UI.Length type.
To use the BackgroundPositionX property, you can assign it a value of type Sandbox.UI.Length or null. Setting it to null will remove any previously set value, effectively resetting the property.
// Example of setting the BackgroundPositionX property var styles = new BaseStyles(); styles.BackgroundPositionX = new Length(50, LengthUnit.Percent); // Set to 50% of the element's width // Resetting the BackgroundPositionX property tyles.BackgroundPositionX = null; // Removes the background position setting
