Breaking Selectors containing ";"

[maxfragg]

#header-wrap[style*="left:0px;

"] span[widgetid=collapse_feeds_btn]>span:before {
    display: inline-block;
}

should be:

#header-wrap[style*="left:0px;"] span[widgetid=collapse_feeds_btn]>span:before {
    display: inline-block;
}

this actually breaks the css-file at least for blink-browsers when formating expanded
