What I’m trying to do

I am the head of a research organization with an open-source research wiki hosted on Obsidian publish. Our wiki is constantly updated with our latest research, but it isn’t (yet) peer-reviewed. For this reason, I want to add a banner on the top of our Obsidian publish site that says ”This is independent, non-peer-reviewed research, and may contain mistakes or errors”.

Things I have tried

The trivial solution to the issue would be to put the disclaimer text on every relevant page in the research wiki. However, the wiki has over 130 pages and I would very much not want to go through each individual one and add it on. I’ve searched online but to my knowledge there is no way to automatically do this with Obsidian publish. Any help would be much appreciated!

Ah ended up finding my own fix, this does require a custom domain but if you add a script file called publish.js with the following content, you can add a banner:

// publish.js

const DISCLAIMER_TEXT = "This is a disclaimer on a banner.";

let banner = document.createElement("div")
banner.innerText = DISCLAIMER_TEXT;
banner.style.textAlign = "center";
banner.style.background = "magenta";
banner.style.color = "white";
banner.style.fontWeight = "bold";
banner.style.fontSize = "0.9rem";
banner.style.padding = "0.5rem";
document.querySelector("body").prepend(banner);
