Now, now, no need to give in. Just hold firm and insist that it was always somebody else’s fault. Humility has no place in this game.

My posts are all suddenly formatting with double spacing.

I cannot figure out how to revert back to single spacing.

This just happened this evening.

Edit: Somehow the Markdown Editor switched itself
to a different setting and I fixed it!

Posting an image…will it work?

Oooh, pretty!

961

WTF ?
What’s happened to MathJax ?
Previously entered examples work still, but new ones don’t.
Eg,
Before:

After:

I guess it has something to do with this:

962

a = b

x=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}

Works for me. I suspect you need to refresh your browser cache of something.

FYI, it’s been common all along that a quote containing some LaTex / MathJax comes out as a mess. Going to the quoted post renders it normally. But the content inside the indented quote box in your post is a mess.

ETA: Some testing shows that included line / paragraph breaks seem to be the problem. IOW this works:
$x=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}$
to render this:
x=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}

but this:
$
x=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}
$
renders as
$
x=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}
$


Here’s your 2nd wordle redone by removing all the line breaks:

\begin{aligned}&\bbox[silver,5px,border:1px solid black]{\texttt H}\bbox[silver,5px,border:1px solid black]{\texttt O}\bbox[yellow,5px,border:1px olid lack]{\texttt I}\bbox[silver,5px,border:1px solid black]{\texttt S}\bbox[silver,5px,border:1px solid black]{\texttt T}\\&\bbox[silver,5px,border:1px olid black]{\texttt G}\bbox[silver,5px,border:1px solid black]{\texttt R}\bbox[silver,5px,border:1px solid black]{\texttt A}\bbox[lime,5px,border:1px solid lack]{\texttt I}\bbox[silver,5px,border:1px solid black]{\texttt N}\\&\bbox[silver,5px,border:1px solid black]{\texttt E}\bbox[silver,5px,border:1px olid black]{\texttt Q}\bbox[yellow,5px,border:1px solid black]{\texttt U}\bbox[lime,5px,border:1px solid black]{\texttt I}\bbox[silver,5px,border:1px solid lack]{\texttt P}\\&\bbox[lime,5px,border:1px solid black]{\texttt C}\bbox[lime,5px,border:1px solid black]{\texttt U}\bbox[lime,5px,border:1px solid lack]{\texttt B}\bbox[lime,5px,border:1px solid black]{\texttt I}\bbox[lime,5px,border:1px solid black]{\texttt C}\\\end{aligned}

MathJax has always been a little weird about embedded line breaks. It seems they’ve solved the weirdness by prohibiting them completely.

963

Hmmm.
Looks a bit shaky.
I refreshed my browser cache but that didn’t help.

Wordle 1,677 4/6*

\begin{aligned} &\bbox[silver,5px,border:1px solid black]{\texttt E} \bbox[silver,5px,border:1px solid black]{\texttt Q} \bbox[yellow,5px,border:1px solid black]{\texttt U} \bbox[lime,5px,border:1px solid black]{\texttt I} \bbox[silver,5px,border:1px solid black]{\texttt P} \\ \end{aligned}

?
That’s better (the “Q” always buggered it up !). But the align now
doesn’t align left.

964

E=mc^2

The best equation!

965

For inline you only need one $. For multi-line, use $$.

Here’s your example
Code:

$$
x=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}
$$

Rendered:

x=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}

Col, thanks. That also solves @pjd’s problem. Here’s his as originally posted but with double $ delimiters instead of single $ delimiters:

\begin{aligned} &\bbox[silver,5px,border:1px solid black]{\texttt H} \bbox[silver,5px,border:1px solid black]{\texttt O} \bbox[yellow,5px,border:1px solid black]{\texttt I} \bbox[silver,5px,border:1px solid black]{\texttt S} \bbox[silver,5px,border:1px solid black]{\texttt T} \\ &\bbox[silver,5px,border:1px solid black]{\texttt G} \bbox[silver,5px,border:1px solid black]{\texttt R} \bbox[silver,5px,border:1px solid black]{\texttt A} \bbox[lime,5px,border:1px solid black]{\texttt I} \bbox[silver,5px,border:1px solid black]{\texttt N} \\ &\bbox[silver,5px,border:1px solid black]{\texttt E} \bbox[silver,5px,border:1px solid black]{\texttt Q} \bbox[yellow,5px,border:1px solid black]{\texttt U} \bbox[lime,5px,border:1px solid black]{\texttt I} \bbox[silver,5px,border:1px solid black]{\texttt P} \\ &\bbox[lime,5px,border:1px solid black]{\texttt C} \bbox[lime,5px,border:1px solid black]{\texttt U} \bbox[lime,5px,border:1px solid black]{\texttt B} \bbox[lime,5px,border:1px solid black]{\texttt I} \bbox[lime,5px,border:1px solid black]{\texttt C} \\ \end{aligned}
967

I’d worked out the $$ bit, but the left align now doesn’t work.
Also doesn’t explain how previous entries in the Wordle thread
render correctly but new ones don’t.

Ah…
\begin{aligned}&\bbox[silver,5px,border:1px solid black]{\texttt E}\bbox[silver,5px,border:1px solid black]{\texttt Q}\bbox[yellow,5px,border:1px solid black]{\texttt U}\bbox[lime,5px,border:1px solid black]{\texttt I}\bbox[silver,5px,border:1px solid black]{\texttt P}\\\end{aligned}
That works, but only with all the code inline (ie with single $).
Looks messy though.

968

Sorted.

\bbox[silver,5px,border:1px solid black]{\texttt B}\bbox[lime,5px,border:1px solid black]{\texttt E}\bbox[yellow,5px,border:1px solid black]{\texttt A}\bbox[silver,5px,border:1px solid black]{\texttt R}\bbox[yellow,5px,border:1px solid black]{\texttt D}
\bbox[silver,5px,border:1px solid black]{\texttt Q}\bbox[silver,5px,border:1px solid black]{\texttt U}\bbox[silver,5px,border:1px solid black]{\texttt I}\bbox[yellow,5px,border:1px solid black]{\texttt L}\bbox[silver,5px,border:1px solid black]{\texttt T}

Cool! Congrats! What trick(s) did you learn that the rest of us might find helpful?

It seems the descender on the Q still messes with MathJax’s head. Oh well; there’s always something.

970

None really !
I think there should be some new alignment syntax that would get it
left justified but I couldn’t work them out - I just kept tweaking it until
it looked ok.
