# 在WordPress中使用LaTeX

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

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