You can do this with a parent with 100% width and children with any .col-[whatever you want] class on each child (or just .col on each child if you don't want them to adjust for screen size). Documentation: https://getbootstrap.com/docs/3.3/css/
You can alternatively create your own CSS with a container with width:100% and display:flex, and children that each have width: 20%.
.parent {
width: 100%;
display: flex;
}
.child {
width: 20%;
}
