Using the card browser, I am editing a card that has a MathJax display equation `\[... \]`. ![image](https://us1.discourse-cdn.com/flex002/uploads/anki2/original/3X/5/1/51c946a939638c29b3532e0442ec682a2f390e41.png) I prefer to put the equation delimiters on different lines than the equation contents, so I added a line break at the location of my cursor in the above image. When I do this, Anki adds ` 
` to the HTML code, causing the equation to stop working, as shown here: ![image](https://us1.discourse-cdn.com/flex002/uploads/anki2/original/3X/f/c/fc07ca92b5b3081de991db062f71aa1ec74edb10.png) Changing `
` to `
` fixes the problem. I don’t know why Anki uses a `div` block here, instead of using `
` (it seems to be because the code already has `div` blocks), but inserting `
` would fix this problem. ```auto Version 24.11 (87ccd24e) Python 3.9.18 Qt 6.6.2 PyQt 6.6.1 ``` ---

You could use \displaylines{} and then use \\ to denote a linebreak. ---

That is a solution for inserting a line break in the displayed equation, but I was talking about just code line breaks. (I’ve never heard of \displayedlines, though. I’ll have to check that out!) ---

I don’t think that’s always true. Sometimes ENTER inserts `
`, which works fine. Anyway, it seems like a bug (or at least bad UI design that) that Anki sometimes inserts div tags inside MathJax equations when this causes them to break ---

You didn’t code-block whatever you were trying to say, so the forum interface ate it – but I think I get the gist. If it “sometimes” works, then just insert the word “sometimes” in the advisement from the manual. You get to the same place! > [@Danika\_Dakika](#): > > If you want to use newlines in a MathJax expression, please use Shift+Enter instead of just Enter, as a normal newline will _ **sometimes** _ prevent MathJax from working correctly.

It’s displaylines, not displayedlines.
