How to scroll to the bottom of the page with Selenium?

When web scraping with Selenium we might encounter pages that require scrolling to the bottom to load more content. This is a common pattern for infinite scrolling pages.

To scroll our Selenium browser custom javascript function window.scrollTo(x, y) can be used. This function scrolls the page to the specified coordinates.

So, if we need to scroll to the very bottom of the page we can use a while loop to continuously scroll until the bottom is reached.
Let's take a look at an example by scraping

from selenium import webdriver
from import By
from import WebDriverWait
from import expected_conditions as EC
import time

driver = webdriver.Chrome()

prev_height = -1
max_scrolls = 100
scroll_count = 0

while scroll_count < max_scrolls:
    driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
    time.sleep(1)  # give some time for new results to load
    new_height = driver.execute_script("return document.body.scrollHeight")
    if new_height == prev_height:
    prev_height = new_height
    scroll_count += 1

# Collect all loaded data
elements = WebDriverWait(driver, 10).until(EC.presence_of_all_elements_located((By.CLASS_NAME, "testimonial")))

results = []
for element in elements:
    text = element.find_element(By.CLASS_NAME, "text").get_attribute('innerHTML')

print(f"scraped: {len(results)} results!")


Above, we're scraping an endless paging example from the website.
We start a while loop and keep scrolling to the bottom until the browser's vertical size stops changing.
Then, once the bottom is reached we can start parsing the content.
