In Selenium automation, a CSS selector is a method used to locate and interact with web elements on a webpage. CSS selectors are powerful and flexible for identifying elements based on their attributes or hierarchy within the HTML structure. Here’s how you can use CSS selectors in Selenium:
By CSS Selector:
You can use the find_element or find_elements method of a WebDriver object to locate elements by CSS selector.
Using CSS Selector Strategies: CSS selectors allow you to target elements using various strategies. Here are some common strategies:
Element by ID: #id
Element by Class Name: .className
Element by Tag Name: tagName
Element by Attribute:[attribute=value]
Element by Attribute Prefix:[attribute^=value]
Element by Attribute Contains:[attribute*=value]
Element by Attribute Ends With:[attribute$=value]
Chaining Selectors: You can also chain CSS selectors to create more specific locators. For example:
element = driver.find_element_by_css_selector(‘div#myDiv input[name=”username”]’)
CSS selectors provide a flexible way to locate elements in Selenium, and you can choose the most appropriate selector strategy based on the specific element you want to interact with on a web page.
