提问by Captain_Meow_Meow
I'm trying to change CSS style of an element (example: from "visibility: hidden;"to "visibility: visible;") using selenium .execute_script. (any other method through selenium+python would be accepted gracefully).
我试图改变一个元素（例如：从CSS样式"visibility: hidden;"来"visibility: visible;"）使用硒.execute_script。（通过 selenium+python 的任何其他方法都将被优雅地接受）。

driver.get("http://www.example.com")
elem = driver.find_element_by_id('copy_link')

Here is an example without using any jQuery. It will hide Google's logo.
这是一个不使用任何 jQuery 的示例。它将隐藏 Google 的徽标。
from selenium import webdriver
driver = webdriver.Firefox()
driver.get("http://www.google.com")
driver.execute_script("document.getElementById('lga').style.display = 'none';")
The same idea could be used to show a hidden element by setting .style.displayto "block", for example.
例如，通过设置.style.display为"block"，可以使用相同的想法来显示隐藏元素。

Here is solution i found using document style sheets. This way is great because you can also add pseudo class styling.
这是我使用文档样式表找到的解决方案。这种方式很棒，因为您还可以添加伪类样式。
script = 'document.styleSheets[0].insertRule("button:focus {background-color: red !important;}", 0 )'
driver.execute_script(script)
