background-image: url(seed_heritage_homepage.jpg); background-size: cover; background-position: center center; background-repeat: no-repeat; background-attachment: fixed` This enables the image to be responsive, fixed according to the viewport of the device, and non-repetitive. The use of media queries further enhances this by applying a low-quality version of the image on devices with screen sizes equal to or less than 780px, optimizing for network bandwidth and faster loading times.

Selenium wait for page to load is implemented using three different methods in Selenium WebDriver: Explicit Waits, Implicit Waits, and Fluent Waits. The main purpose of these waits is to ensure that the WebElements are available for performing tests after a certain period of time, allowing them to handle dynamic content loading with AJAX or other technologies. This can be particularly useful when testing websites that use such features, as it prevents errors caused by trying to interact with elements that are not yet loaded. The choice of wait method depends on the specific requirements of the test automation script and the desired level of control over the polling frequency.

Cucumber is a Behavior Driven Development framework used for automated browser testing that enables diverse project stakeholders to come up with test scenarios written in plain English, using the Gherkin language which can be easily understood by both technical and non-technical people.

Cucumber is widely used in organizations adopting Agile methodologies, where stakeholders from various backgrounds collaborate on product testing. Setting up Cucumber in Eclipse or IntelliJ requires installing the necessary JARs and configuring the project structure, with Maven providing an easier approach by adding dependencies directly to the pom.xml file.

The use of Asserts and Verify in Selenium WebDriver is crucial for validating web applications or websites during the process of test automation. Hard Asserts are used when a decision needs to be taken regarding "What if the test(s) result in a failure?" If the error (or issue) being encountered is a minor one, you might want the test execution to continue. In case of serious errors, it is better to abort the execution of the test case (or test suite). Hard Asserts are used when you want to halt the execution of the test script (or test method) when the assert condition does not match with the expected result. Soft Asserts, on the other hand, are used when the test script (or test method) need not be halted when the assertion condition does not meet the expected result. Soft Asserts are used in cases where the failure of a test step does not result in the failure of the test scenario. Both Hard Asserts and Soft Asserts provide two options for passing parameters to assert methods, which can include custom messages for displaying error messages when asserts are thrown. Assertions (or Asserts) play an integral role when it comes to Selenium automation testing. They are used to check if the tests have passed or failed by looking into the results of the respective Assert methods. The use of Hard Asserts and Soft Asserts differs in terms of whether they raise exceptions upon failure, with Soft Asserts continuing execution after a test step fails.
