Five dimensions are stablished:
- 240px - 479px
- 480px - 799px
- 800px - 1279px
- 1280px - 2079px
- 2080px - 4096px
And two orientations:
Properties may be different from dimension and orientation, or conditioned to any of these. It is important to note that the division between sizes is not linear. To correct this properties, It is convenient to think on first establish the properties that affect small screens and then the bigger ones.
In practice, only three measures are used: Small, Medium and Large. The first option diminutive (tiny) by its dimensions is not practical to display information, so you can choose to deploy a message indicating the problem. In the case of the Huge dimension, because the dimensions have already been supported by the previous version (large) can be handled smoothly.
