How to Set Up and Use Cursor for Web Development

Introduction

AI is something that every person relies on in the technology field. It has now become a crucial part of the development workflow. Now Developers can rely on AI-powered tools to make their work easier, instead of spending a lot of time finding answers through documentation or browsing forums, developers can just write the requirement and AI-powered tools will generate code, troubleshoot errors,  can identify bugs and suggest improvements in real time. This makes development a lot easier because it reduces coding work that developers have to do.

Cursor is one of the most popular AI-Powered code editor available today.  Cursor is a version of Visual Studio Code (VS Code). It looks and feels the same when you use both of them. The combination of a code editor with advanced AI capabilities makes Cursor more flexible. Developers can use simple prompts to generate code,  improve the existing code, adds additional features if required via prompts, understands complex files and solve errors without leaving the editor. Cursor has an interface like VS Code which makes it easier for users who use it often.

Cursor is now becoming the preferred code editor. Many developers are now using cursor as their primary development environment. It has the ability to understand your project, suggest code improvements and helps with both frontend and backend development which makes coding much easier and efficient. Whether you’re creating a simple website using HTML, CSS, Javascript or developing a full-stack web application, while maintaining code quality cursor can reduce development time.

This blog is about using Cursor for web development. It will show you the complete setup process, explain key features and how to use Cursor to build modern websites.

What is Cursor AI?

Cursor AI is an AI-Powered code editor that helps developers to edit, write and manage code efficiently. It is easy for VS Code users to get started, since it shares the same open-source foundation as Visual Studio Code and, so it feels similar to anyone who has used VS code before.

Cursor is not a normal code editor, it’s more than that. It has built-in AI which makes the development process easier. Usually we search on the internet for solutions but with cursor you can just simply describe your requirements in plain english. Cursor then understands your requirements and generates code accordingly, it also explains existing code, fix errors, and suggests improvements.

Cursor supports multiple AI-models, which makes it easier for developers to choose the model that fits best for their workflow and coding requirements.
It supports models such as:

1. OpenAI – GPT models
2. Anthropic – Claude models
3. Google – Gemini models
4. DeepSeek – DeepSeek models
5. xAI – Grok models
6. Cursor – Cursor’s own AI models

It understands what the requirement is or the project is about and gives accurate or relevant suggestions, which makes the development process faster. Developers can easily switch between models depending on the task whether its writing code, debugging, editing existing code.

Some of the key features of Cursor include:

1. AI Chat – Ask coding related questions and get answers instantly within the editor.
2. Code Generation – By describing your requirements it can create HTML, CSS, Javascript, PHP and other code.
3. Debugging – Receive suggestions and identify errors and fix them quickly.
4. Refactoring – Improves the structure of existing code, which makes it more readable and easier to maintain.
5. AI-Powered Autocomplete – Get code suggestions as you type.
6. Terminal Assistance – Get help in fixing command line errors and terminal errors.

With these features Cursor helps developers build websites and web applications faster while maintaining clean code.

Step3 – Understanding Cursor AI interface

Once you open Cursor, you will find an interface similar to VS Code.

Explorer: It displays your project files and folder.
Editor: Code editor is the main area of your cursor where you can edit and write your code.
AI Chat: You can interact with the cursor’s AI chat by sending prompts. It will identify error, suggest improvements, edits code.
Terminal: It allows you to run commands, install packages and start development servers.
Extensions: Install tools that improve your web development workflow.
AI Autocomplete: Get code suggestions as you type.

Step4 – Create or Open a Project

Create a new folder in your computer, you can create a folder named my-website for example. After creating a folder open cursor and then open a project this will open your files directly and select your project folder created. For existing project select open project on cursor and select the existing project folder created.

Step5: Start building a website with Cursor

Once the project is selected, instead of writing code manually you can start using its AI features to build your website. You can describe your requirements related to your website in a prompt and the Cursor will generate the code.

For example, we will build a Website Performance Dashboard called “WebPulse” using Cursor.

Create a professional and responsive Website Performance Dashboard called “WebPulse” using HTML, CSS, and vanilla JavaScript. Create separate files for HTML, CSS, and JavaScript. Include a sidebar navigation, top header, performance statistics cards, a performance analytics chart, Core Web Vitals, traffic sources, and a recent performance issues section. Add search and filtering functionality, a light/dark mode toggle, and make the dashboard responsive for desktop, tablet, and mobile devices. Use realistic sample data and do not connect to any external APIs. Keep the design clean, modern, and professional.

Cursor will analyze the prompt and generate the required code for the project.

Note – The dashboard uses sample data for demonstration and is not connected to a real performance API.

Step6 – Review and Customize Generated Code

Cursor can improve existing sections of the project as per your requirements, you can describe your changes and cursor will find the relevant code and update it.

For example, to improve the performance statistic cards, give Cursor the following prompt:

Redesign the four performance statistic cards. Make them larger, add a small icon to each card, increase the main metric value size, add a visible percentage change indicator, and add a subtle hover animation when the user moves the mouse over a card. Keep the existing data unchanged.

After the changes are completed, review them. You can keep to accept the changes or undo to reject them.

Cursor can be used to edit existing code through a prompt, making it easier to improve a website without manually editing every part of the code.

Step 7: Debug and Fix Errors Using Cursor

You may encounter errors during development when adding or modifying any features. Cursor can analyze the project files and suggest improvements and help identify the cause of an issue.

For example, you can ask:

The dark mode toggle is not working. Check the HTML, CSS, and JavaScript, identify the issue, and fix it without changing the existing design.

Cursor will identify the problem and suggest the required changes. Always test the fix in the browser after applying it to make sure the feature works correctly.

Step 8: Test and Refine the Website

After making changes and fixing errors, test the website in the browser to make sure everything works as expected. Use Live Server to open the WebPulse dashboard and check its layout and functionality on different screen sizes.

Test important features such as:

• Navigation and buttons
• Search and filters
• Dark mode
• Performance chart
• Responsive layout
• Interactive elements

You can also ask Cursor to review the project:
Review the entire project for HTML, CSS, and JavaScript issues, responsiveness, accessibility, and code quality. List any problems you find without making changes.

Conclusion

Cursor makes web development easier by bringing AI assistance directly into the code editor. From setting up a project and generating code to modifying features, fixing errors, and improving existing code, developers can use Cursor throughout the development process.
As demonstrated with the WebPulse project, Cursor can help build websites using simple natural-language prompts while allowing developers to review and control the changes.
With a good understanding of HTML, CSS, and JavaScript, Cursor can become a useful tool for building and improving websites more efficiently while reducing repetitive coding work.
