How can I create a three-column horizontal layout with CSS only, without modifying the HTML structure?

3 Column Layout with CSS Only

In HTML, you have a layout with three columns arranged vertically:

<div class="container">
   <div class="column-center">Column center</div>
   <div class="column-left">Column left</div>
   <div class="column-right">Column right</div>
</div>

You want to arrange these columns horizontally, similar to the grid below, without altering the HTML structure:

----------------------------------------------------
|              |                   |               |
| Column left  |   Column center   | Column right  |
|              |                   |               |
----------------------------------------------------

To achieve this, use CSS properties:

.column-left{ float: left; width: 33.333%; }
.column-right{ float: right; width: 33.333%; }
.column-center{ display: inline-block; width: 33.333%; }

For a more flexible grid system, create a grid system with a larger number of columns:

.column {
    float: left;
    position: relative;
    width: 20%;
    
    /*for demo purposes only */
    background: #f2f2f2;
    border: 1px solid #e6e6e6;
    box-sizing: border-box;
}

.column-offset-1 {
    left: 20%;
}
.column-offset-2 {
    left: 40%;
}
.column-offset-3 {
    left: 60%;
}
.column-offset-4 {
    left: 80%;
}

.column-inset-1 {
    left: -20%;
}
.column-inset-2 {
    left: -40%;
}
.column-inset-3 {
    left: -60%;
}
.column-inset-4 {
    left: -80%;
}

And use HTML like this:

<div class="container">
   <div class="column column-one column-offset-2">Column one</div>
   <div class="column column-two column-inset-1">Column two</div>
   <div class="column column-three column-offset-1">Column three</div>
   <div class="column column-four column-inset-2">Column four</div>
   <div class="column column-five">Column five</div>
</div>
