Steps to reproduce

Create a test page with a styled element:

<style>a { background: purple; }</style>
<a id="a1">foo</a>

Request the element’s “backgroundColor” property with "[element]/css/backgrounColor". The WebDriver returns a value of "", whereas calling window.getComputedStyle(document.getElementById('a1')).backgroundColor returns "rgb(128, 0, 128)", which is the expected value (the /css command is expected to return the computed values of CSS properties).

    • I’m using the Leadfoot WebDriver library (https://github.com/theintern/leadfoot) to retrieve an element reference and then call getComputedStyle. The getComputedStyle call ends up making a POST to:

    • Thank you for the update. To able to minimize the repro could you please also confirm your test result in case of using background-color property instead of background.

    • Sorry for taking so long to get back to you on this. I’m now using Edge build 14366 and the most current insider MicrosoftWebDriver with Selenium 2.53.1. I’ve tried all combinations of specifying “background” and “background-color” in the CSS and requesting “background” and “backgroundColor” via WebDriver. In all cases, Edge returns an empty response.

    • Ok, after testing this a bit more, I can get Edge to return styles. My problem was that I was using a camel case name (“backgroundColor”), but Edge appears to only understand hyphenated names (“background-color”). It took me a while to try this because I’ve always used camel case names with the other browsers (IE, Chrome, Firefox).
