@matsutakehoyo I just checked and you're not alone 😄. Many others have already reported the issue. My guess is, GitHub will eventually fix it. Meanwhile, may the force be with you.

@manasesjesus Thanks for your comments! Just for future references? What is the best place to report this issue, I couldn’t find a specific repo for this and ended up here…

Here are some resources @matsutakehoyo :

• GitHub Support - Bug Report
• GitHub Support
• GitHub Community Forum

@Banyc FYI
you may also report your bugs.

@matsutakehoyo @Banyc there was an update. You may check if your issues are solved now.

It seems it is fixed now (?)

Is double dollar sign broken for some reason just for me?

It's super broken. Always use math code blocks.

There still seem to be issues across the board with math markdown on GitHub. For me, I can only use $ or $$ because math code blocks aren't working. It seems hit or miss, so part of me wonders if there are conflicts between how GitHub or MathJax is implementing the code vs how certain browsers are drawing the math code.

Another interesting issue is that I'm finding if you create a large square root symbol, $$ causes the vertical bar of the symbol to get cut off unless you zoom in, whereas $ formats it properly no matter what. I actually just experienced this while updating the docs for a Microsoft repository, ironically.

对任意整数 $i$
For every integer$i$

You need at least a space between inline math and normal text.

Using $$E \equiv \sum_i \dot q_i \frac{\partial L}{\partial \dot q_i} -L \tag{1}$$; the \tag{_} will throw anything into this weird vertical jumble.

The only working way I've found out is by using arrays, like:

$$
\begin{array}{lr}
    a^2 + b^2 = c^2 & \text{(1)}
\end{array}
$$

$$ \begin{array}{lr} a^2 + b^2 = c^2 & \text{(1)} \end{array} $$

You can add an <span> tag to add an reference to the equation (make sure to have line feeds right after <span> and right before the </span>:

<span id="eq2">

$$
\begin{array}{lr}
    a^2 + b^2 = c^2 & \text{(2)}
\end{array}
$$

</span>

That way, you can add the link to the Equation (2) by using [Equation (2)](#eq2)
