JOSM: mapcss, style use after checked elemstyles.mapcss

When you use the JOSM mapcss (default), you have this one checked, as a mapstyle.

When there is a access=no on a way the JOSM mapcss (default) and more access examples. The style show this in JOSM. Fine.

elemstyles.mapcss

When I also checked the New highway colors, mapstyle. Then these access from the default is showing. No problem.

/****/ / access restrictions tags / /****/

way[access?!]::core_access { z-index: -1; width: +2; color: no#ff8080; dashes: 2,2; } way[access=permissive]::core_access { z-index: -1; width: +2; color: permissive#80ff80; dashes: 2,2; } etc.

Making your own mapcss for highways. How can you overrule this access part of the elemstyles.mapcss style. Not showing this access=no visualisation and more. But you want the JOSM mapcss (default) checked.

Someone can give me a hint?

Is this the place to ask JOSM questions?
