[FIXED] Cannot find element by class attribute using selenium

Issue

I cannot find element by class attribute using selenium from this site. Unfortunately I get an NoSuchElementException. But at the same time I am sure that this element exists on the page:

<div class="page-header mb-3">
   <h1>Log In to Djinni</h1>
</div>

Here code of my program:

dr = webdriver.Chrome()
dr.get("https://djinni.co/login")
dr.maximize_window()
header = dr.find_element(By.CLASS_NAME, "page-header mb-3") #NoSuchElementException
print(header.text)

Can anyone tell me what the reason is?

Solution

Simple mistake.

You are looking for the class page-header mb-3 - this is two classes, page-header and mb-3

If you specify either of these classes instead of both it will work.

dr = webdriver.Chrome()
dr.get("https://djinni.co/login")
dr.maximize_window()
header = dr.find_element(By.CLASS_NAME, "page-header") #This works
print(header.text)
