How To Use LaTeX in Posts
To include LaTeX () code in your post, use the following:
$
latex your-latex-code-here$
So, for example,
$
latex i\hbar\frac{\partial}{\partial t}\left|\Psi(t)\right>=H\left|\Psi(t)\right>$
produces
Understanding LaTeX Error Messages
If your LaTeX code is broken, instead of the equation, you’ll see an ugly yellow and red error message.
We can’t provide support for LaTeX syntax, but there are plenty of useful guides elsewhere online. Or a quick post in our forums 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 the math
environment (such as \begin{align} ... \end{align}
), you will get an error:
How To Adjust 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 ‘s font size commands:
s= |
font size | Example |
---|---|---|
-4 | \tiny |
|
-3 | \scriptsize |
|
-2 | \footnotesize |
|
-1 | \small |
|
0 | \normalsize (12pt) |
|
1 | \large |
|
2 | \Large |
|
3 | \LARGE |
|
4 | \huge |
Changing Colors in LaTeX
WordPress tries to guess the background and foreground colors of your site and generates the LaTeX image accordingly. But, you can also change the colors if you wish. You can do this by specifying bg
and fg
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$
Available LaTeX Packages
