当我翻阅我的档案时
b'/* a comment */\n.chat {\n background: #fff;\n color: green !important;\n margin: 1em\n }\n.chat-history {\n height: 100px;\n padding: 8px 24px;\n overflow-y: scroll;\n margin: 1em\n }\n#live-chat header {\n background: #293239;\n border-radius: 5px 5px 0 0;\n color: green !important;\n cursor: pointer;\n padding: 16px 24px;\n margin: 1em\n }'
我想创建一个缩进的CSS文件 在写入CSS文件之前,可以使用函数
sheet.cssText.decode('ASCII')
以ASCII格式解码cssText
