Irregular bootstrap column wrapping

This is caused by skills with 2 lines of text or more. It's a well-known bug when using float property. Here is a little picture to understand :

[Bootply] The issue

Option #1 : Force the height

Your first option is to force elements to have the same height :

.tutor {    height: 500px;}

• [Pro] Simple and work everywhere
• [Con] Use a magic number
• [Con] Limit the number of lines in skills
• [Con] Useless whitespaces on modile version

[Bootply] Force height

Option #2 : Use a clearfix

Your second option is to use a clearfix, and force the 5th element to be on a new line (same for the 9th, the 13th...) :

.tutors-listing > .row > .col-md-3:nth-child(4n+1) {    clear: both;}

• [Pro] Doesn't limit the number of lines in skills
• [Pro] No useless whitespaces
• [Pro] No magic number
• [Con] One CSS rule per size (xs/sm/md/lg)
• [Con] The rule depends of your grid (.col-xx-3)

[Bootply] Clearfix

In my case I wanted to show 3 items per row on large screens, 2 on medium screens, and 1 on smaller screens.

You may also uncomment the background colors to verify when the effect is triggering.

Sometimes, I run into this issue as well. I recommend trying to overwrite any padding or margin that you do NOT need. Try changing the margin to 0 first. Then remove some of the padding. That has helped in some of my cases.
