更新：在当前的SeleniumLibrary（3.2+）中，有一个专用关键字：Get Element
Attribute（获取元素属性）

SeleniumLibrary for Robot
Framework不支持获取CSS属性的值。但是，value_of_css_propertySelenium
Python模块中有一种方法可以完全做到这一点。

为了在元素上调用方法，Call Method可以在任何Robot变量或对象上使用standard关键字。在下面的示例中，我使用Google主页创建了一个自定义关键字和一些示例。应该根据您的目的轻松修改它们。

    # a CSS property inherited from the <body> tag.
