推荐答案
更新:在当前的 SeleniumLibrary (3.2+) 中有一个专用关键字:获取元素属性
Update: in the current SeleniumLibrary (3.2+) there is a dedicated keyword: Get Element Attribute
SeleniumLibrary for Robot Framework 不支持获取 CSS 属性的值.但是，Selenium Python 模块中有一个名为 value_of_css_property 的方法可以做到这一点.
Getting a value of a CSS property is not supported in the SeleniumLibrary for Robot Framework. However, there is a method called value_of_css_property in the Selenium Python module that does exactly that.
为了在元素上调用方法，可以在任何机器人变量或对象上使用标准关键字Call Method.在下面的示例中，我创建了一个自定义关键字和一些使用 Google 主页的示例.它们应该很容易根据您的目的进行修改.
In order to call a method on an element the standard keyword Call Method can be used on any Robot variable or object. In the below example I created a custom keyword and some examples using the Google main page. They should be easily modified for your purpose.
