Default CSS Theme

Hi. I like the darker look of Logseq on the Logseq homepage ( and I am wondering what CSS them is used to make it look like that. The default dark theme that comes with the app looks different from the one on the website - text in each ‘node’ comes up in a semi-white box like the image attached etc. I had a look at custom themes on the awesome-logseq website (GitHub - logseq/awesome-logseq: Awesome Logseq resources created by the community <3) but couldn’t find any with that look. Does anyone know if the theme is available somewhere else for users to use by any chance? Thanks. Screen Shot 2021-08-20 at 6.07.04 am
