So yeah I've read plenty of questions asking this, but I can't figure out how it can be done via custom calculations performed by JavaScript. I want one fixed column on the left side to size correctly when it's resized within container, and not to interfere with the columns along it. Here is the example code, so far what I've achieved when trying to do it in pure Bootstrap and CSS: http://www.bootply.com/arSNSzWA1U
But there lies a problem. On bigger screens it sizes incorrectly because of the fixed attribute for which percentage measures of the whole window are being taken, not of the parent.
So, my question is, how it can be brought back to normal with JavaScript/JQuery? Thanks in advance!
