在WordPress中使用LaTeX

WordPress.com supports \LaTeX, a typesetting system that’s really good at formatting mathematical formulas and equations.

Using LaTeX

To include latex \LaTeX$, code in your post, use the following:

$latex your-latex-code-here$

So, for example,

i\hbar\frac{\partial}{\partial t}\left|\Psi(t)\right>=H\left|\Psi(t)\right>

produces

i\hbar\frac{\partial}{\partial t}\left|\Psi(t)\right>=H\left|\Psi(t)\right>

LaTeX Error

If your \LaTeX code is broken, instead of the equation you’ll see an ugly yellow and red error message. Sorry, we can’t provide support for \LaTeX syntax, but there are plenty of useful guides elsewhere online. A quick post in our forums, or the Stack Exchange LaTex forum, might find you a solution. One thing to keep in mind is that WordPress puts all of your \LaTeXcode inside a \LaTeX math environment. If you try to use \LaTeX that doesn’t work inside themath environment (such as \begin{align} ... \end{align}), you will get an error:

\LaTeX&s=X

LaTeX Size

You can change the size of the LaTeX by specifying an s parameter after the \LaTeX code.

$latex \LaTeX&s=X$

Where X goes from -4 to 4 (0 is the default). These sizes correspond to \LaTeX‘s font size commands:

s= font size Example
-4 \tiny \LaTeX
-3 \scriptsize \LaTeX
-2 \footnotesize \LaTeX
-1 \small \LaTeX
0 \normalsize (12pt) \LaTeX
1 \large \LaTeX
2 \Large \LaTeX
3 \LARGE \LaTeX
4 \huge \LaTeX

LaTeX Colors

WordPress tries to guess the background and foreground colors of your site and generates the \LaTeX image accordingly. But, you can change the colors. You can specify bg andfg parameters after the \LaTeX code to change the background and foreground colors, respectively. The colors must be in hexadecimal RGB format: ffffff for white, 0000ff for bright blue, etc.

$latex \LaTeX&bg=ffcccc&fg=cc00ff&s=4$
