Equation alignment

Support
1

Hello,
i know that to align text you need to use HTML syntax:
<p style="text-align:center;">text</p>
But if I want to align an equation($\varSigma=\lbrace a\rbrace$), how can i do it?
Because with that expression i can't:
<p style="text-align:center;">$\varSigma=\lbrace\epsilon\rbrace$</p>

Multi-line equation alignment

It's a bit verbose, but you can try something like

$$
\begin{aligned}
	D F(x, y) &= \text{rotate and scale}(x, y)\\
		&= r \begin{pmatrix}
			\cos Ο‘ & -\sin Ο‘\\
			\sin Ο‘ & \cos Ο‘
		\end{pmatrix}
\end{aligned}
$$

The &s aren't visible when rendered and are the point that will be aligned.

Single-line equation alignment

Try block math (two $ symbols)

$$
    \text{This should be centered}
$$

Any of these should work,

<div style="width: min-content; margin-left:auto;">

$\TeX$

</div>

or

<span style="float: right;">

$\TeX$

</span>

or

<div style="text-align: right;">

$\TeX$

</div>

There might also be a KaTeX operator for it: See Supported Functions Β· KaTeX for a general list of supported functions.
