Quick Fix

Follow these step-by-step instructions to identify and resolve the issue. Each step shows a common mistake (the Wrong approach) followed by the corrected code (the Right approach) along with the expected outcome.

Step 1: Define named lines

/* Wrong */
.container {
    display: grid;
    grid-template-columns: 200px 1fr 200px;
}

/* Right */
.container {
    display: grid;
    grid-template-columns: [sidebar] 200px [content] 1fr [sidebar-end];
}

Expected output: Lines are named sidebar, content, sidebar-end.

Step 2: Place items with named lines

/* Wrong */
.item-main {
    grid-column: 2 / 3;
}

/* Right */
.item-main {
    grid-column: content / sidebar-end;
}

Expected output: Placed between named lines instead of numbers.

Step 3: Multiple names for one line

/* Wrong */
.container {
    display: grid;
    grid-template-columns: [sidebar-start] 200px [sidebar-end content-start] 1fr [content-end];
}

/* Right */
.container {
    display: grid;
    grid-template-columns: [s-start] 200px [s-end c-start] 1fr [c-end];
}

Expected output: Lines can have multiple space-separated names.
