5.3.step 1. Page-Margin Field Build Terms and conditions

Plus the container model meanings inside the CSS2.step 1 [CSS21], therefore the measurements conditions for the CSS Intrinsic Measurements [CSS3-SIZING], the next terminology is outlined for use on after that web page-margin field computations:

The whole page’s left edging depth, leftover cushioning, webpage town depth, proper padding, and you may best edging width. In other words, this is the distance between your web page box’s kept correct edging corners. It quantity is used whenever calculating size of the big and you will base web page-margin boxes.

  • If perhaps one to container possess ‘width: auto’, the put depth are solved therefore the amount of the fresh external widths translates to readily available depth.
  • If A good and you can C each other provides ‘width: auto’, spreading the room to each and every field as follows:
