The spec says that a horizontal scrollbar is supposed to be always shown if overflow-x: scroll is set.
On my website I often post code in a <pre>-Block. As this has no predefined width, but the surrounding div does have a maximum (defined as percentage), it seems that I can not figure out how to achieve the following:
In case a code block is not too wide, hide the horizontal scrollbar.
If it exceeds the width, show a scrollbar.
Any hints? I think I have tried most of the combinations of overflow-x and -y, but none seem to do what I want.
