I'm having some problems with the columns. I supposed to have 5 columns for md and larger devices and 4 for sm and 3 for xs. The thing is that in large screens all my columns are on the left part of the screen. I've been going through my code but can't find out why it's been like this.
Essentially I want it to be like this, and preferably centered within each column (without having words stacked on each other): 

rowaround thecol-'s. Onerowhas space for 12col-'s. If you want to have 3col-'s in xs you can give each div the classcol-4because 12 / 3 = 4. Same principle for sm, but you can't divide 12 by 5
