Extract CSS Property

This node extracts a CSS property from a WebElement. For the specified CSS property name, the property values are appended as string column to the input table. In case, a CSS property is not present, a missing value cell is appended.

Note: “Shorthand” CSS properties such as background, font, border, etc. are usually not supported, instead you must use the explicit longhand property names, such as background-color, font-size, etc.

Color values are returned as RGBA strings, e.g. for a color property green Selenium will return rgba(0, 255, 0, 1).

Options
