Layouts

{ and how to get them right }

(*) This is satire

*

CSS layout modes are algorithms determining the position and the size of boxes based on the way they interact with their sibling and ancestor boxes

{ display: block; }

The good ol' way

Make me float: right;

- A block element

{ display: block; }

{ display: table; }

The anti-hero

Chakras

  • Not an HTML table
  • Allows proper vertical alignment
  • Gets the job done
  • ...

Tables are bad!

- Some website out there

(for layout)

  • Limit what you can do in terms of layout
  • Make redesigns MUCH harder
  • Semantically incorrect

{ display: table; }

Tables are for Tabular Data. Period.

- Another website

{ display: flex; }

  • Aligns and distributes space among items in a container
  • Vertical and horizontal flows
  • Makes devs happy!
