Drawbacks of driver.js
Performance:
When using Driver.js on your website it’s important to consider its impact, on performance. Adding JavaScript and CSS can lead to longer loading times especially if you have tours with multiple elements or animations. While running these tours you might experience slowdowns.
Accessibility:
Driver.js may not work seamlessly with all keyboard navigation patterns, which could pose accessibility challenges, for users who depend on them. Depending on how your tours set up and their complexity screen readers might face difficulties, in interpreting the content provided.
Control and flexibility:
Creating and personalizing driver.js tours can be a bit more intricate, than using highlighting tools. It’s important to consider how your website is designed and styled as driver.js overlays and popovers may not seamlessly blend with your existing user interface elements.
