It would be really appreciated Thanks!

• Look for the .css file under File Browser > Styles
  
• Go to the bottom of the file and add: @media amzn-kf8 {html {margin-left: -36px; margin-right: -36px; }} (You can pick whatever negative value you prefer, doesn't have to be -36px)
  
  From here it can get tricky if you're not familiar with css due to all the variables, but you can try this as a starting point:
  
  
• Search for "margin-left:" and "margin-right:" (e.g., "margin-left: 0" or "margin-right: 1em", etc.) If the value is 0, 0%, 0em, or any variation of 0, delete the whole rule (e.g., delete "margin-left: 0;"). If the value is a number, you should probably leave it, but this is where understanding css helps.
  
• Search for "margin:" This can take many forms, e.g., "margin: 0" or "margin: 0 5px" or "margin: 0em 5px 0em 5px", etc. If this rule turns up, it's best to learn some css to figure out how to revise it to your liking.
  
• Search for @page (e.g., @page {margin: 5px;} ) and delete the whole rule
  
• For line-height, search for "line-height:" (e.g., line-height: 1em) and delete the whole rule
  

Good luck!
