What are some differences between CSS selector and XPath based locators?
Xpath allows bidirectional flow which means the traversal can be both ways from parent to child and child to parent as well. Css allows only one directional flow which means the traversal is from parent to child only. Xpath is slower in terms of performance and speed. Css has better performance and speed than xpath.
