FF und Chromium rendern details/summary unterschiedlich

[JürgenB]

Hallo Rolf,

@supports (selector(::marker)) {
  summary { list-style: none; }
  summary::before { content: "► "; }
  details[open] summary::before { content: "▼ "; }
}

im Wiki mache ich es so:

/* Originalsymbole vor den Summary entfernen und eigene Symbole definieren */
#sitenav summary::-webkit-details-marker { 
	display: none; 
}
#sitenav summary { 
	list-style-type: none; 
}
#sitenav details summary::after { 
	font-family: arial_unicode_ms; 
	vertical-align: top; 
}
#sitenav ul details:not([open]) > summary::after { 
	content: ' ►'; 
}
#sitenav ul details[open] > summary::after { 
	content: ' ◄'; 
}

Gruß
Jürgen
