This is the eleventh post in a series examining modern CSS solutions to problems I've been solving over the last 13+ years of being a frontend developer. Visit ModernCSS.dev to view the whole series and additional resources.

"How do I center a div?"

Well, this new resource has you covered! We'll look at 3 categories:

• Vertically and Horizontally (XY)
• Vertical (Y)
• Horizontal (X)

Each category shows solutions that explore using grid, flexbox, and block element layout.
