How Can I Avoid Double Borders in CSS Grid Layouts?

Preventing Double Borders in CSS Grid

In CSS Grid, it's possible to create a grid layout of elements that can be positioned and sized according to a specified template. However, you might encounter an issue where double borders appear between grid items, resulting in an undesired visual effect.

To remedy this, consider the following alternative approach:

Using Background and Grid-Gap Properties

Instead of defining actual borders around grid items, you can use the background-color property on the container to achieve the desired border color and the grid-gap property to control the "border" width.

Here's an updated code snippet that demonstrates this approach:

.wrapper {
  display: inline-grid;
  grid-template-columns: 50px 50px 50px 50px;
  border: 1px solid black;
  grid-gap: 1px;
  background-color: black;
}

.wrapper > div {
  background-color: white;
  padding: 15px;
  text-align: center;
}

By utilizing this technique, you eliminate the need for actual borders around the grid items, resulting in a clean and seamless layout without double borders.
