CSS Grid Border Tutorial for Beginners and Experts

CSS Grid is a powerful layout system that allows you to create complex and responsive layouts with ease. With CSS Grid, you can create a grid container and define rows and columns to arrange your content.

To add a border to a grid item, you can use the grid-template-columns and grid-template-rows properties, as seen in the example code: `grid-template-columns: repeat(3, 1fr) / 1px solid #000;`. This code creates a grid with three columns and adds a 1-pixel solid black border between them.

A border can be added to a grid item using the grid-template-columns and grid-template-rows properties, as demonstrated in the example code.

A fresh viewpoint: Grid Template Css

CSS Grid Basics are a fundamental building block for creating complex layouts.

Grid containers are created using the display property set to grid or inline-grid.

To define the grid, you need to specify the grid-template-columns and grid-template-rows properties.

The grid-template-columns property can be defined using the fr unit, which represents a fraction of the available space.

A unique perspective: Grid Column Css

To create a grid container, use the following code on a service-grid wrapper when the view-state is larger than mobile: `grid-template-columns: repeat(12, 1fr); grid-template-rows: repeat(12, 1fr); min-width: 300px; max-width: 1170px; grid-gap: 0px;`.

The grid gap is set to 0px to have clean lines for the interior dividers balanced between grid cells, so there should be no extra gap space.

Each item in the CSS Grid has a default border on the top in all cases, and adds a border on the left starting post-mobile for tablet and desktop rendering.

To set border lines on a CSS Grid layout, we need to be able to change the number of grid columns without affecting the borders. A grid with a missing grid item should not break the borders.

We can achieve this by using pseudo-elements, specifically ::before and ::after, to create the border lines. This is because borders have too many limitations, and using pseudo-elements allows us to position them absolutely.

For another approach, see: Css Grid Lines

By setting the parents to position relative, we can attach the pseudo-elements as children. We'll use the ::after pseudo-element for row lines and the ::before pseudo-element for column lines.

To add a border in a row line, we use a width of 100vw, which spans the entire width of the grid container. A height of 1px sets the height of the line, and top -1px pushes the line to the top.

Here are the properties we use for a row line:

Similarly, for a column line, we use a height of 100vh and left -1px to move the line to the left side of each grid item.

To add inner borders to your CSS Grid layout, you'll want to consider the options outlined in Example 3. One common workaround is to give the grid container a background color and make a small grid-gap between cells, but this can have limitations.

A better approach is to use the ::before and ::after pseudo-elements to create horizontal and vertical borders. This involves making all grid cells positioned, which shouldn't have any side effects, and setting overflow to visible.

You can target specific cells using the :nth-child pseudo-class to add grid lines to the left of each cell. For example, targeting cells in the second and third column allows you to add grid lines to the left of each cell.

To create the horizontal grid lines, you'll use the ::after pseudo-element. This can be achieved by setting the height of the pseudo-element equal to the cell height plus the gap height using calc().

The key to omitting borders in CSS grid is using the nth-child pseudo-class to target specific grid items.

You can remove the external top border by targeting the first two cells with nth-child lines of code, as seen in tablet view. This is done by removing the top-border across the first two cells, which is essential for the 2-row tablet view.

To remove the external left border, use the nth-child(odd) capability to pull the border off the first, third, and fifth columns, all of which are the left-side columns. This is exactly how it's done in the tablet view example.

Resetting the border-top and border-left everywhere is crucial when focusing on the desktop view. This is done by resetting the borders removed in the previous media query to ensure a clean slate.

Removing the top borders for the first three cells is done using the nth-child(-n+3) equation in the desktop view. This is a specific technique used to target the first three cells.

Every third cell left border can be removed using the nth-child(3n+1) equation, starting with the 4th cell. This is a clever way to target every third cell.

Finally, to complete the desktop view look, you can pull the left border off the first cell by calling first-child. This is the final step in removing the external borders on the 3-column desktop view.

Preventing double borders in CSS Grid can be a real challenge. You just need to add a `.grid { grid-gap: 1px; }` to fix the superposition of elements.

One way to collapse borders is by using the `outline` property. This is a quick fix that can help avoid double borders.

To make it work, you need to position the pseudo-elements absolutely, so you need to set the parents to position relative. Adding CSS `position relative` in the grid item class makes your parent element ready to have a pseudo-element as a child while positioning absolute.

Here's a quick rundown of the steps to take:

By following these steps, you can create a grid layout with borders that don't overlap.

To set border lines on a CSS Grid layout, you need to be able to change the number of grid columns without affecting the borders. A grid with a missing grid item should not break the borders.

You can use pseudo-elements for everything, including borders, because they have fewer limitations than borders. To position the pseudo-elements absolutely, you need to set the parents to position relative. This can be done by adding CSS position relative in the grid item class.

The width of a row line should be 100vw, which spans the entire width of the grid container, to account for gaps between grid items. The height of a row line should be 1px, and the top position should be -1px to push the line to the top.

For a column line, use the ::after pseudo-element and set its width to 100vw, height to 100vh, and left position to -1px to move the line to the left side of each grid item.

You can also add borders to your grid, but only between the cells, not around the grid itself. This can be achieved by giving the grid container a background color and making a small grid-gap between the cells.

To target cells in the second and third column using the pseudo-class :nth-child, you can add grid-lines to the left of each cell using the ::before pseudo-element. Set the height of the pseudo-element equal to the cell height plus the gap height using calc().
