How to locate an element with multiple class names?

Question

I\'m trying to click on the following element with the class name equals \"clean right\":

Answer 1

You can't pass multiple classnames as argument through find_element_by_class_name() and doing so you will face an error as:

invalid selector: Compound class names not permitted

There are multiple approaches to solve this usecase and you can use either of the following Locator Strategies:

• If the element is uniquely identified only through the classname clean you can use:

  driver.find_element_by_class_name("clean")
  

• If the element is uniquely identified only through the classname right you can use:

  driver.find_element_by_class_name("right")
  

• If both the classnames, clean and right are mandatory to identify the element, you can use css-selectors as follows:

  driver.find_element_by_css_selector("li.clean.right")
  

• As an alternative you can also use xpath as follows:

  driver.find_element_by_xpath("//li[@class='clean right']")
