Align DIVs on the same line

To align and display multiple <div> tags on the same line, you can use one of these CSS properties: display: inline-block;, or float ('left', or 'right').
- To make a responsive design, so the DIV elements to remain aligned on the same line when the browser's window is resized, use percentage values for the sizes of the DIVs, and margins.

In the following example, the <div> elements have inline-block property.

<style>
#left, #center, #right {
 position: relative;
 display: inline-block;
 margin: 1em 0.1em 0.1em 0.8%;
 padding: 0.1em;
 background: #ebebfb;
 border: 2px solid blue;
}
#left {
 width: 22%;
 height: 20em;
}
#center {
 width: 52%;
 height: 30em;
}
#right {
 width: 16.2%;
 height: 20em;
}
</style>
