Assessment required for Marking up a letter

I have just completed The Marking up a letter assessment. I want someone to go through my code and advice me on how to improve it.

Hi there @Ashutosh_Bisht! I have looked through your code, and it looks mostly really good. The only comment I had was that you have quite a lot of unneccessary <br> tags in your paragraphs, breaking lines at certain lengths. I’m assuming you did this to set the letter to be a certain width, but you need to use CSS for such tasks, not HTML elements.

Apart from that, the work is great — well done!

Thankyou sir, I m still not into css …but I will try to learn it as soon as possible.
