  1. What will the CSS Shapes specification allow us to do on our websites? Word Wrap! It provides web designers with a new way to change how the content flows inside and around arbitrarily complex shapes

    The element must be floated. Future levels of CSS Shapes may allow us to define shapes on non-floated elements, but not yet.

    The element must have intrinsic dimensions.The height and width set on an element will be used to establish a coordinate system on that element.

  2. How can we get started?

    In order to use CSS Shapes in Chrome Canary today, you have to enable the experimental features flag.

    You can apply a shape to an element using one of the Shapes properties
