Web development is the process of creating a website or web application. This can include anything from a simple static website to a complex dynamic web application. The process typically involves a team of designers, developers, and testers who work together to create the final product. Web design & development are essential to creating a successful website.

The process of web development can be broken down into a few key steps: 

1.Planning: This is the stage where you determine what kind of website you want to create, and what functionality it will need to have. You'll also need to decide on a domain name and hosting plan.

2.Coding: Once you have a plan in place, it's time to start coding! This is the part where you'll actually build out the website using HTML, CSS, and JavaScript.

3.Testing: Before you launch your website, it's important to test it out to make sure everything is working correctly. This includes running unit tests and user acceptance tests.

4.Deployment: Finally, once your website is ready to go, you'll need to deploy it to a server so that people can access it online.

5.Maintenance: Once everything is up and running, it's important to maintain and update the site on a regular basis. This includes adding new content, fixing bugs, and making sure everything continues to work properly.
