What language is this?

"html, body": {
"height": "auto",
"width": "auto",
"margin": "0",
"padding": "0",
"color": "#000",
"background": "#fff",
},
"a[href]:after": {
"content": '" (" attr(href) ")"',
"color": "#000",
"font-size": "90%",
},
".page__body": {
"margin-left": "0",
"margin-right": "0",
"padding": "0",
},
"pre": {
"border": "1pt solid #000",
"background": "none",
"box-shadow": "none",
"page-break-inside": "avoid",
"padding": "0.3em",
},
".page__header, .page__footer": {
"display": "none !important",
},

Looks like CSS. Actually it's an except from a Python program
with nested dicts!
