里面有个custom.css文件,你只要修改这个文件就可以了. /* jupyter notebook中显示字体如何调整？ - 李懿虎的回答 - 知乎 https://www.zhihu.com/question/40012144/answer/124731496 */ /* Placeholder for custom user CSS mainly to be overridden in profile/static/custom/custom.css This will always be an empty file in IPython */ .CodeMirror pre {font-family: Monaco; font-size: 10pt;} * {font-family: Monaco;} div.output_area pre {font-family: Monaco; font-size: 10pt;} div.input_prompt {font-family: Monaco; font-size: 10pt;} div.out_prompt_overlay {font-family: Monaco; font-size: 10pt;} div.prompt {font-family: Monaco; font-size: 10pt;} span.cm-comment {font-family: Monaco !important; font-style:normal !important; color:#FFAE3C !important;} C:\Users\user\.jupyter\custom\custom.css
