There are several common challenges that developers may encounter when contributing to a project using HTML, CSS, and JavaScript. Some of these challenges include:
• Performance issues: Developers must ensure that their code is efficient and optimized for performance.
• Accessibility issues: This includes ensuring that the code is compliant with accessibility standards and that it can be
navigated using keyboard shortcuts.
• Code maintainability: Developers must ensure that their code is easy to read, understand, and maintain.
• Version Control: Developers must ensure that their code is version controlled so that they can revert to an older version of
the code if needed.
• Debugging: Use the developer tools in your browser to inspect the code and identify the source of the bug.
• Research: Look for solutions online by searching for similar issues and reading documentation.
• Experimentation: Try different solutions and see what works best. This can help you identify the most effective solution
for a specific bug.
• Seek help: If you are stuck and can't figure out how to fix a bug, don't hesitate to ask for help from other developers or
members of the community.
• Testing: Test your code in different browsers, devices, and operating systems to ensure that it works as expected.

Some other small challenges:-
• GitHub commands but it solved by practice
• some syntax errors So read the code again and again and focus on the console
• branch conflicts so make diff branch for every PR
• forking issues so remember to sync every time to make new PR
