An integer value simply refers to the line number where the item should start. For example, a value of 1 will start the item at the first vertical grid line.

2. Span keyword

The span keyword allows you to specify how many columns an item should occupy. For example, span 2 would make the item span two columns.

VI. Example

The following code demonstrates how to use the grid-column-start property within a CSS Grid layout:

        .grid-container {
            display: grid;
            grid-template-columns: repeat(3, 1fr);
            gap: 10px;
        }

        .item1 {
            grid-column-start: 1;
            grid-column-end: span 2;
            background-color: lightblue;
        }

        .item2 {
            grid-column-start: 2;
            background-color: lightgreen;
        }

        .item3 {
            grid-column-start: 3;
            background-color: lightcoral;
        }
        

This CSS will create a grid with three columns. The first item will start at the first column and span two columns, while the second and third items start in the second and third columns respectively.

Frequently Asked Questions (FAQ)

1. What is the difference between grid-column-start and grid-column?

While grid-column-start defines where an item begins in the column track, grid-column is a shorthand property that sets both grid-column-start and grid-column-end in one declaration.

No, grid-column-start accepts only integers, the span keyword, or the auto keyword but does not support fractional units.

3. How does grid-column-start affect responsive design?

By using the grid-column-start property within media queries, you can adjust the layout dynamically according to different screen sizes, thus enhancing responsive design.

4. What happens if I specify a grid-column-start value that does not exist?

If you specify a grid-column-start value that exceeds the number of columns defined in the grid, the browser will automatically place the item in the next available slot.
