Update html-questions.md

[Srajal16]

I am very excited to make my first open-source contribution! As someone passionate about front-end development and eager to give back to the community, I saw the opportunity to enhance the html-questions.md section with two new questions that cover fundamental HTML concepts. These questions aim to provide valuable content to those preparing for front-end development interviews.

I am thrilled to be a part of this collaborative effort. I understand that the pull request process involves back-and-forth discussions, and I'm eager to work with you to refine these contributions and make them even better.

Thank you for the opportunity to contribute, and I look forward to your feedback!
