Spacing between columns in CSS grids

You can set the distance between grid columns. This is done using the column-gap property, which is set on the parent element.

Let's set the distance in pixels between columns in the grid:

<div id="parent">
	<div>1</div>
	<div>2</div>
	<div>3</div>
	<div>4</div>
	<div>5</div>
	<div>6</div>
	<div>7</div>
	<div>8</div>
	<div>9</div>
</div>

#parent {
	display: grid;
	column-gap: 20px;
	grid-template: 1fr 1fr 1fr / 1fr 1fr 1fr;
	padding: 10px;
	border: 2px solid #696989;
	width: 600px;
	height: 200px;
}
#parent > div {
	padding: 10px;
	border: 1px solid #696989;
}

Create a table where the distance between columns is 20%.
