Full-Width Elements By Using Edge-to-Edge Grid

Creating full-width elements within a limited-width container, such as a centered text column, requires clever CSS techniques. One common approach uses relative left positioning and a negative left margin based on the viewport width. While this method has limitations (e.g., needing hidden overflow on the body and a centered container), it's relatively simple and doesn't interfere with other container elements.

Alternative methods using CSS Grid have been widely discussed:

• Tyler's "Breaking Out with CSS Grid Layout" and Rachel's response.
• Rachel's "Editorial Design Patterns With CSS Grid And Named Columns."
• Selen Gora's "Setting the box in container to full width with CSS Grid."
• Bryan Robinson's "Use CSS Subgrid to layout full-width content stripes in an article template."

These methods share a common assumption: an edge-to-edge grid spanning the entire page. This raises the question: Is using body { display: grid; } for the entire page layout a practical approach? While some developers do this, it presents potential challenges.

Several drawbacks exist:

1. Headers and footers, typically full-width elements, require explicit placement and spanning within the grid, adding complexity compared to using simple block-level elements. A more flexible approach might involve a central edge-to-edge grid with block-level headers and footers.
2. Positioning all elements within a central column (e.g., article > * { grid-columns: 2 / 3; }) to selectively expand some items feels cumbersome. For predominantly centered content, a parent element managing layout offers a simpler, more robust solution than individually positioning each element on the grid.

While not inherently flawed, the edge-to-edge grid approach can feel less intuitive and potentially more complex for many layouts. This observation might stem from a preference for simpler, more modular approaches.

It's crucial to avoid applying display: grid; directly to the element. Browser extensions injecting elements into the body can disrupt the grid layout. A better practice is to use a child <div> to contain the grid, mirroring the React best practice of avoiding direct body manipulation for improved scoping and maintainability.</div>
