After reviewing numerous queries on this topic, I am struggling to find a solution using custom calculations in JavaScript. My goal is to have a fixed column on the left side that resizes properly within its container without affecting adjacent columns. You can see my attempt at achieving this using pure Bootstrap and CSS here: http://www.bootply.com/arSNSzWA1U
However, a problem arises when viewing it on larger screens as the sizing is incorrect due to the fixed attribute calculating percentages based on the entire window rather than the parent.
Therefore, my question is how can I rectify this issue using JavaScript/JQuery? Thank you in advance!
