A page is divide in to 12 columns.

Lets think we want to use to response grid view with 12 columns.

So width=100% / 12 columns = 8.33 %

One column is 8.33% of the whole page.

Then we make a class for each of the 12 columns.

Lets update the above example with this concept.


Example : Grid view columns

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
* {
box-sizing: border-box;
}
.footer {
border: 1px solid blue;
}
.header {
border: 1px solid blue;
}
.row::after {
content: "";
clear: both;
display: table;
}
[class*="column-"] {
float: left;
border: 1px solid blue;
}
.column-1 {width: 8.33%;}
.column-2 {width: 16.66%;}
.column-3 {width: 25%;}
.column-4 {width: 33.33%;}
.column-5 {width: 41.66%;}
