When working on your web design assignment, ensuring that your HTML and CSS code is valid and error-free is crucial. Clean code not only improves functionality but also enhances compatibility across browsers. Several reliable tools can help you validate your code before submission.

W3C Validator: The W3C Markup Validation Service (https://validator.w3.org/) is the most widely used tool for validating HTML code. It checks your HTML markup for syntax errors, incorrect nesting, or deprecated tags and provides detailed feedback for fixes. Similarly, the W3C CSS Validator (https://jigsaw.w3.org/css-validator/) is perfect for checking CSS code against web standards.

HTMLHint: This is a customizable tool that scans your HTML code for errors and provides actionable suggestions. It is simple to use and often integrates with popular code editors, helping streamline the debugging process.

CSS Lint: If you're looking for a reliable tool to validate your CSS, CSS Lint (http://csslint.net/) is a great option. It not only highlights errors but also suggests optimizations to make your stylesheets cleaner and more efficient.

Integrated Development Environments (IDEs): Tools like Visual Studio Code and Sublime Text often have built-in linters and plugins, such as Prettier or ESLint, that validate HTML and CSS in real time.

Browser Developer Tools: Modern browsers like Chrome and Firefox come with built-in developer tools that allow you to inspect and debug code. Use the "Inspect" feature to identify issues in your HTML structure or CSS styles.

By using these tools, you can catch common mistakes early and ensure your project meets the necessary standards. For anyone seeking web design assignment help, these tools are a must-have to deliver polished and professional work. Not only will validated code impress your instructors, but it will also enhance your understanding of proper coding practices.
