Description

Can we Implement Different Values for Horizontal & Vertical Box? Today I found a use case where if I could change only vertical box-sizing to content-box, I could solve my issue only via CSS. Though for now I have to use JS.

For different horizontal & vertical values, can we implement 2 values syntax?
E.g.: box-sizing: border-box content-box;
If we have 2 values first will be applied horizontally and second will be applied vertically.

New Working Draft: CSS Box Sizing Level 4.

box-sizing: border-box | content-box | padding-box?
why not padding-box is implemented?

Research direction

Start by reading the CSS Box Sizing Level 4 Working Draft linked in the issue and compare it with the proposed two-value box-sizing syntax. The issue also asks why padding-box is not implemented; done would require a resolved specification direction for these questions rather than a localized code change.
