pagedown html resume - How to move disclaimer section within aside section to the last page?

Taking the template resume from pagedown as an example, I would like the disclaimer section (currently on the bottom right of the first page, reading "This resume was made with the R package pagedown. Last updated on 2021-08-18.") moved to the bottom of the last page.

I've pasted the template r-markdown document below, but it is also accessible by opening a new R-markdown document in R Studio, and by selecting the "From Template" section and "HTML Resume".

I understand from the documentation and reading various customization solutions that CSS would be involved, but I'm unsure how to use CSS to force that section to the last page.

### Currently searching for a PhD student position

Please note that this is a *real* resume, and I'm really looking for a PhD
student position at the moment. I made this resume because Yihui asked me
if I'd like to test the **pagedown** package with my resume. If you are
interested in my background and skills, please feel free to contact me.

The best way for what you want is to ask the author to support this feature. Here is a hack to do so without changing the source code. Add this chunk to the end of your Rmd

```{js move_disclaim, echo=FALSE}
(function() {
    var pages 
    var timer = 0;
    var changeDC = setInterval(function() {
        pages = document.querySelectorAll('.pagedjs_page');
        if(pages.length !== 2 && timer <= 5000) {
            timer += 200;
            return;
        }
        if(pages.length !== 2 && timer > 5000) return clearInterval(changeDC);
        var firstPage = pages[0];
        var lastePage = pages[pages.length - 1];
        var aside = firstPage.querySelector('#aside');
        var asideClone = aside.cloneNode();
        asideClone.id = "aside_last";
        var disclaim = document.querySelector('#disclaimer');
        asideClone.appendChild(disclaim);
        lastePage.querySelector('.pagedjs_page_content > div').appendChild(asideClone);
        clearInterval(changeDC);
    }, 200);
})()
```

What does it do:

1. Why don't I only use CSS? Because I can't. The style of disclaimer is position: absolute within a div of position: relative. So it is locked inside the relative div. There is not much you can do about it (unless trick I don't know).
2. My thought is to use js to move that element into the last page.
3. The page layout is rendered on the fly with an async js function when every time you open the webpage. Maybe not as what you have imagined, when Rmarkdown finished rendering, we should have page ready. No, it is not, the author uses a library called {paged.js} to do the rendering. It generates the layout every time you open the browser tab.
4. The author did not emit any event when the rendering is done, so I have no way to know the rendering is done. So I don't know when I can start to move.
5. The way I do is to add a timer that runs every 200ms. If rendering is done, I do the move and remove the timer or if it takes more than 5s, I consider it something wrong, clear the timer and do nothing.
6. One thing you need to define is pages.length !== 2. You need to know how many pages it will generate and this should be a fixed number you can easily get.
