Layout Grid - Maximum width - Border

[sieweb]

Hi and good evening,
If I use a layout grid and set Maximum width to, for example 900 px, a border round that grid will always span the complete browser width neglegting the 900 px.
Is there a way to avoid that and to set the grid to true 900 px?

If you put a '-' in front of the number, the border (and background) will be limited to the specified max width.
