How to Move right column below the left in smaller screen size

I have a left and right cloumn and I want the right column to shift below the other when the screen gets smaller

1 Answer

Hey Erica,

The best way to do this is to just set each column to display: block; so that they will stack on top of each other using a media query that targets at or below a certain screen size. For example,

/* Target screens from 699px width and lower */
@media screen and (max-width: 699px) {
  .col-1 {
    display: block;
  .col-2 {
    display: block;

so this is what I have written for just normal viewing but when I plugin the CSS you have written it does nothing. I need the "right" to be positioned below the "left and I need "truck" to be positioned below "personnel".

.table { position: relative; border-bottom:15px solid #B22E1B; background-color:#DADADA; margin-top:30px; margin-bottom:0; padding:20px; overflow:hidden; } .left { float: left; width:50%; } .right { float: right; width:50%; }

ul.style1 li { text-align: left; text-indent:-10px; margin-left:10px; margin-top: 20px; padding-right:5px; padding-left:5px; }

.table-1 { position: relative; width:100%; overflow:hidden; margin-bottom:50px; color: #B22E1B; }

personnel { float:left; width:40%; text-align: left; color: #B22E1B; margin-top: 20px;}

.truck { width:60%; float: right;}
