HTML SASS simple grid system placing items incorrectly - css

Question

I'm trying to build a simple grid system using SASS:
app.scss:
.row,
.col {
box-sizing: border-box;
}
.row:before,
.row:after {
content: " ";
display: table;
}
.row:after {
clear: both;
}
.col {
position: relative;
float: left;
}
.col + .col {
margin-left: 1.6%;
}
.col-1 {
width: 6.86666666667%;
}
.col-2 {
width: 15.3333333333%;
}
.col-3 {
width: 23.8%;
}
.col-4 {
width: 32.2666666667%;
}
.col-5 {
width: 40.7333333333%;
}
.col-6 {
width: 49.2%;
}
.col-7 {
width: 57.6666666667%;
}
.col-8 {
width: 66.1333333333%;
}
.col-9 {
width: 74.6%;
}
.col-10 {
width: 83.0666666667%;
}
.col-11 {
width: 91.5333333333%;
}
.col-12 {
width: 100%;
}
#media only screen and (max-width: 550px) {
.col-1,
.col-2,
.col-3,
.col-4,
.col-5,
.col-6,
.col-7,
.col-8,
.col-9,
.col-10,
.col-11,
.col-12 {
width: auto;
float: none;
}
.col + .col {
margin-left: 0;
}
}
// Body
body {
font-family: $default-font;
font-weight: normal;
font-size: 13px;
color: $text-default;
}
.app {
width: auto;
height: 100%;
border-style: outset;
border-width: 1px;
padding: 5px;
}
header-container.scss:
#import '../App/App.scss';
.header-container {
border-style: outset;
border-width: 1px;
border-radius: 5px;
padding: 10px;
}
My HTML:
<header className='header-container'>
<div className='row'>
<div className='col-2'>
<p>Person 1</p>
</div>
<div className='col-2'>
<p>Person 2</p>
</div>
</div>
</header>
Person 1 is appearing above Person 2, not at the side as I expect the grid to work. I cannot find out what's wrong, but I think I'm missing something basic.

Answer 1

You're missing .col on the column elements
.row, .col {
box-sizing: border-box;
}
.row:before, .row:after {
content: " ";
display: table;
}
.row:after {
clear: both;
}
.col {
position: relative;
float: left;
}
.col + .col {
margin-left: 1.6%;
}
.col-1 {
width: 6.86666666667%;
}
.col-2 {
width: 15.3333333333%;
}
.col-3 {
width: 23.8%;
}
.col-4 {
width: 32.2666666667%;
}
.col-5 {
width: 40.7333333333%;
}
.col-6 {
width: 49.2%;
}
.col-7 {
width: 57.6666666667%;
}
.col-8 {
width: 66.1333333333%;
}
.col-9 {
width: 74.6%;
}
.col-10 {
width: 83.0666666667%;
}
.col-11 {
width: 91.5333333333%;
}
.col-12 {
width: 100%;
}
#media only screen and (max-width: 550px) {
.col-1,
.col-2,
.col-3,
.col-4,
.col-5,
.col-6,
.col-7,
.col-8,
.col-9,
.col-10,
.col-11,
.col-12 {
width: auto;
float: none;
}
.col + .col {
margin-left: 0;
}
}
// Body
body {
font-family: $default-font;
font-weight: normal;
font-size: 13px;
color: $text-default;
}
.app {
width: auto;
height: 100%;
border-style: outset;
border-width: 1px;
padding: 5px;
}
.header-container {
border-style: outset;
border-width: 1px;
border-radius: 5px;
padding: 10px;
}
<header class='header-container'>
<div class='row'>
<div class='col col-2'>
<p>Person 1</p>
</div>
<div class='col col-2'>
<p>Person 2</p>
</div>
</div>
</header>

Answer 2

For now, your col-2 class doesn't make your div float:left;
Two possibilities:
You add the class col to your divs
You set all the class starting with col to float:left; You can do it this way: [class^="col"] { float:left; }
Well, I hadn't seen that you are using className and not class, so you can change it accordingly: [className^="col"] { float:left; }
