How to Disable CSS in Python Selenium Using ChromeDriver with ChromeOptions

Problem Statement

Disabling CSS in Chrome Selenium using ChromeDriver is necessary to enhance page loading speed. While it's straightforward to disable images and JavaScript, attempting to disable CSS by modifying the 'profile.default_content_setting_values' preferences doesn't seem to work.

Solution

To disable CSS and show the page without it, you can use the following code:

from selenium import webdriver

options = webdriver.ChromeOptions()
prefs = {'profile.default_content_setting_values': {'cookies': 2, 'images': 2, 'javascript': 2,
                           'plugins': 2, 'popups': 2, 'geolocation': 2,
                           'notifications': 2, 'auto_select_certificate': 2, 'fullscreen': 2,
                           'mouselock': 2, 'mixed_script': 2, 'media_stream': 2,
                           'media_stream_mic': 2, 'media_stream_camera': 2, 'protocol_handlers': 2,
                           'ppapi_broker': 2, 'automatic_downloads': 2, 'midi_sysex': 2,
                           'push_messaging': 2, 'ssl_cert_decisions': 2, 'metro_switch_to_desktop': 2,
                           'protected_media_identifier': 2, 'app_banner': 2, 'site_engagement': 2,
                           'durable_storage': 2, 'css': 2}}  # Add 'css': 2 to the dictionary to disable CSS
options.add_experimental_option('prefs', prefs)
options.add_argument("start-maximized")
options.add_argument("disable-infobars")
options.add_argument("--disable-extensions")
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get('https://play.google.com/store')

Explanation

This code modifies the 'profile.default_content_setting_values' preferences by adding 'css': 2 to the dictionary. This effectively disables CSS. The browser options are then configured to maximize the window, disable the info bar, and disable extensions. Finally, the desired URL is loaded into the browser.
