# Line breaking in MathJax (Common-HTML)

This is sort of a reopening of the bug reported by Najib Idrissi here.

The Common-HTML render does not break lines.

Compare this to the HTML-CSS output of the same code.

You could imagine how long the single-line output was.

(Both were taken from this answer, in Firefox 43 on Arch Linux 64bit.)

• Ah, I have felt compelled to edit a couple of questions where this was happening, using the align* environment to manually force line breaks. I did not realize it was a consequence of the newer rendering mechanism. – hardmath Jan 31 '16 at 10:56
• That's probably not a terrible idea in general. The align environments offer better control over when and how the lines are broken. – Asaf Karagila Jan 31 '16 at 11:07
• I saw an example in a comment yesterday, where the situation is worse (surprise). Then, scrolling isn't even an option. – pjs36 Jan 31 '16 at 14:49
• @pjs36: The breakage of comments with excessively wide MathJax formulas is a different bug (although, obviously, this bug makes it worse). I have a user script that fixes it, among other things. – Ilmari Karonen Feb 7 '16 at 16:42
• @Ilmari: Not necessarily, though. – Asaf Karagila Feb 7 '16 at 16:44
