html - Stop absolutely positioned div from overlapping text

Question

Here is a simplification of my layout:

    <div style="position: relative; width:600px;">
        <p>Content of unknown length, but quite quite quite quite quite quite quite quite quite quite quite quite quite quite quite quite long</p>
        <div>Content of unknown height</div>
        <div class="btn" style="position: absolute; right: 0; bottom: 0; width: 200px; height: 100px;background-color: red;"></div>
    </div>

Answer 1

The solution for me was to create a second invisible div at the end of the content of unknown length, this invisible div is the same size as my absolutely positioned div, this ensures that there is always a space at the end of my content for the absolutely positioned div.

This answer was previously provided here: Prevent absolutely-positioned elements from overlapping with text However I didn't see (until now) how to apply it to a bottom right positioned div.

New structure is as follows:

<div id="outer" style="position: relative; width:450px; background-color:yellow;">
        <p>Content of unknown length</p>
        <div>Content of unknown height </div>
        <div id="spacer" style="width: 200px; height: 25px; margin-right:0px;"></div>
        <div style="position: absolute; right: 0; bottom: 0px; width: 200px; height: 20px; background-color:red;">bottom right</div>
    </div>
