Sure see below:
Index.js:
export default function (kibana) {
return new kibana.Plugin({
id : 'custom_css',
require: ['kibana'],
uiExports: {
hacks: [
'plugins/custom_css/hack'
]
}
});
};
hack.js:
import 'plugins/custom_css/less/main.less'
and my main.less:
a[data-test-subj="logo"] * {
display: none;
}
a[data-test-subj="logo"] {
background: url(URL TO YOUR LOGO) no-repeat 0 0;
background-size: auto 26px;
border-bottom: none;
background-position: 10px 10px;
}
