Set font of Jupyter

Edit css file below.

.jupyter/custom/custom.css

I'm using migu-1m font by downloading for Windows. For Ubuntu, no font setting required because it's default font is not bad.

custom.css

.CodeMirror pre,
.CodeMirror-dialog,
.CodeMirror-dialog .CodeMirror-search-field,
div.output pre,
div.output_html td,
div.prompt,
div.completions select,
div.container pre,
div.tooltiptext pre,
.terminal-app .terminal
{
    font-family: migu-1m;
    font-size: 10pt;
}
