I use a snippet:
<style>h1 {clear: both; font-size: 1.4em; margin: 0; padding: 1em 0 2em; text-align: center;}
h2 { font-size: 1.2em; margin: 0; padding: 1em 0 2em; text-align: center;}
p { font-size: 1em; text-align: justify; margin-bottom: 1em;}
.col1, col2 {float: left; width:50%}
div.col1 p, div.col2 p {margin-left:0; margin-right: 0.75em}</style>
<h1></h1>
<div class="col1">
<h2></h2>
<p></p>
<p></p>
</div>
<div class="col2">
<h2></h2>
<p></p>
<p></p>
</div>
Paste text of language one after the first h2. Paste text of language two after second h2. Adjust styles as needed. Can print out very well as pdf. Works well with calibre reader. Probably won't work with Amazon ebooks. To adjust for English being more compact than German, reset widths separately to 45% and 55%. Best regards, Pop
