Mark Edgington:

If antialiasing is turned off, viewing code via Kallithea on chromium (ver 58.0.3029.110) looks terrible, resulting from the following CSS rule that is used:

```
#!css
code pre {font-family: Lucida Console, Consolas, Monaco, Inconsolata, Liberation Mono, monospace;}
```

If I simply disable this CSS rule in the web-browser's inspector interface, the fonts revert to the default browser fixed-width fonts, and they look nice.
