webdriver object has no attribute find_element_by_css_selector

This error occurs when you try to use the method "find_element_by_css_selector" on a webdriver object that does not support this method.

There are a few possible reasons why this error may occur:

1. You may have misspelled the method name. Double-check that you have spelled it correctly: "find_element_by_css_selector".

2. You may be using an outdated version of the webdriver or the Selenium library. Make sure you have the latest version installed.

3. You may be using the wrong type of webdriver. Not all webdrivers support the "find_element_by_css_selector" method. For example, if you are using the "Firefox webdriver", it does not support this method. You should use the "Chrome webdriver" or the "Edge webdriver" instead.

To fix this issue, make sure you are using the correct webdriver and that you have spelled the method name correctly.
