How to Disable CSS in Chrome
Google Chrome loads cascading style sheets specified on Web pages and uses them to style the Web pages. If you want to view how a Web page appears without its CSS style sheets, you can disable CSS in Google Chrome to see the unstyled Web page. Google Chrome doesn’t include an option to disable cascading style sheets, but you can disable CSS on a per-page basis with a browser extension, such as Web Developer or Pendule.
Open the Web Developer or Pendule extension page on the Chrome Web Store. Click the “Install” button to install the extension.
Click the gear-shaped icon at the top right corner of the Google Chrome window to open the Web Developer or Pendule extension’s menu.
Select the “CSS” option in the Web Developer extension and click “Disable All Styles,” or click the “Style Sheets” option in Pendule and click “Disable All Styles.” After you click the option, the page will re-display without the styles.
