I recently stumbled across the mathematics textbook Numerical Analysis 9th edition by Burden and Faires and I thoroughly enjoyed the style of it. I was able to find a link too here: https://fac.ksu.edu.sa/sites/default/files/numerical_analysis_9th.pdf. I was wondering if someone could help me with trying to mimic the style.

Since the style of the book seems rather broad, I will start by trying to tackle these parts first:

• Theorems, tables, ect. in the margin notes section and aligning them with content in the body section
  
  
  
  
  • I have some starter code for this using the marginnote package and using reversemarginpar to get the notes in the left margin but I was curious if someone could do better or improve on this
  
  
  
  


• Spanning blue bars over each of the section headers that span the left margin notes and body section
  
  
  
  
  • Unsure of how to do this as current attempts produce lines spanning the body section and right margin notes
  
  
  
  


• Having graphs and images in centered style formats in the blue frame boxes
  
  
  
  
  • I am pretty sure that the mdframed package can handle this but I just wanted to see what others may say
  
  
  
  

If anyone needs any further information or examples from me, I would be happy to provide it. Thank you for your time and help!

Sample code for the margin notes:

usepackage{geometry}

usepackage{marginnote}



geometry{

a4paper,

left=2in,

right=1in,

marginparwidth=1.75in,

marginparsep=.25in

}

reversemarginpar
