For Win 7
Google Chrome: C:\Users\%USERNAME%\AppData\Local\Google\Chrome\User Data\Default
http://www.chromium.org/user-experience/user-data-directory
override Default/User StyleSheets/Custom.css in your user directory with something like:
/* Keep .platform-mac to make the rule more specific than the general one above. */
body.platform-mac.platform-mac-snowleopard .monospace,
body.platform-mac.platform-mac-snowleopard .source-code {
font-size: 11px !important;
font-family: Menlo, monospace;
}
body.platform-windows .monospace, body.platform-windows .source-code {
font-size: 18px !important;
font-family: Consolas, Lucida Console, monospace;
}
body.platform-linux .monospace, body.platform-linux .source-code {
font-size: 11px !important;
font-family: dejavu sans mono, monospace;
}
修改完后不用重启Chrome，立马生效。
