Innovationm Interview Questions and Answers
Ques:- How does flexbox work in CSS
Right Answer:
Flexbox, or the Flexible Box Layout, is a CSS layout model that allows items in a container to be arranged and aligned efficiently. It works by defining a container as a flex container using `display: flex;`, which enables its direct children (flex items) to be laid out along a main axis (horizontal or vertical). You can control the alignment, direction, spacing, and size of these items using properties like `flex-direction`, `justify-content`, `align-items`, and `flex-wrap`. This makes it easier to create responsive layouts without using floats or positioning.

Ques:- How does a web server handle an HTTP request
Right Answer:
A web server handles an HTTP request by following these steps:

1. **Receive Request**: The server listens for incoming HTTP requests on a specific port (usually port 80 for HTTP or port 443 for HTTPS).
2. **Parse Request**: It parses the request to extract the method (GET, POST, etc.), URL, headers, and body.
3. **Process Request**: The server determines how to respond based on the request. This may involve retrieving files, querying a database, or executing server-side scripts.
4. **Generate Response**: It creates an HTTP response, which includes a status code (like 200 for success), headers, and the requested content (like HTML, JSON, etc.).
5. **Send Response**: The server sends the response back to the client (usually a web browser) over the network.
6. **Log Request**: Optionally, the server logs the request details for monitoring and analysis.
Ques:- What is the difference between class and ID in CSS
Right Answer:
In CSS, a class is defined with a dot (.) and can be applied to multiple elements, while an ID is defined with a hash (#) and should be unique to a single element on a page.
Ques:- What are cookies sessions and local storage in web development
Right Answer:
Cookies are small pieces of data stored on the user's computer by the web browser while browsing a website, used for tracking and remembering information about the user. Sessions are temporary storage on the server that keeps track of user data across multiple requests during a single visit, typically expiring when the user closes the browser. Local storage is a web storage feature that allows websites to store data in the user's browser persistently, even after the browser is closed, with no expiration time.
Ques:- What are the important test scenarios for testing a web site?
Right Answer:
1. Functionality Testing: Verify all links, forms, and buttons work as intended.
2. Usability Testing: Assess the user interface and user experience for ease of use.
3. Performance Testing: Evaluate load times and responsiveness under various conditions.
4. Security Testing: Check for vulnerabilities, data protection, and secure transactions.
5. Compatibility Testing: Ensure the website works across different browsers and devices.
6. Accessibility Testing: Confirm compliance with accessibility standards for users with disabilities.
7. Regression Testing: Test existing features after updates or changes to ensure they still function correctly.
8. Localization Testing: Verify the website's content and functionality for different languages and regions.
