Dear Sir/Ma'am.
I have read the job description, and I am confident that I can do the task, I am an expert in HTML, CSS, JS and many other languages. I have done many similar projects where HTML and CSS have been the primary language used. I have much experience in HTML and CSS, and I am certified in these from Cambridge. The reason I am charging less is that I lost access to my old Freelancer account and this is my new account, so I want to get good reviews on this account. I am looking forward to talking to you about this project. I am very good at meeting deadlines.
Best Regards.
