For instance, if you try to compile the following markdown code with pandoc (using 1.12): ``` markdown Page 1 ------ This is a very long code line that will appear on every slide even on page three Page 2 ------ My content Page 3 ------ My last content ``` using this command: pandoc -s -t dzslides test.md -o /tmp/test.html the long code line will appear on every slide. Using pre-wrap fixes the problem by forcing word wrap of code. The only drawback is that it requires IE 8 [according to MDN](https://developer.mozilla.org/fr/docs/Web/CSS/white-space), which make it less compatible. A workaround it to wrap the code when writing it, but if you consider inline code tags using the accents \`\` in markdown this is not possible.
