Posted on November 7, 2013 by Kellie Hodgins

Writing can be tough. That’s why Jetpack includes features that make the writing process easier. Post directly to your blog with an email, easily embed content with a shortcode, or use LaTeX to display complex mathematical equations and formulas.

Writing Prompt Block - The Writing Prompt block provides a prompt to start your writing. It also allows you to include a link to other people's writing on the same topic in the WordPress.com Reader.
Markdown (Classic Editor) - Markdown lets you compose posts and comments with links, lists, and other styles using regular characters and punctuation marks. Markdown is used by writers and bloggers who want a quick and easy way to write rich text, without having to take their hands off the keyboard, and without learning a lot of complicated codes and shortcuts.
Copy Post - Copy Post allows you to easily start new posts based on existing posts. It supports Posts, Pages, Jetpack Testimonials, and Jetpack Portfolios.
Comment Likes - Give your users the power to show comments some love! To access Comment Likes, the site must have Comment Likes enabled and you must be logged into your WordPress.com account.

Shortcode Embeds - Shortcodes allow you to embed videos from YouTube, tweets from Twitter, and other media across the web directly in to your WordPress-powered site. This feature also allows you to embed elements by pasting URLs on a line by itself in your visual editor.
Beautiful Math with LaTeX - LaTeX is a powerful markup language for writing complex mathematical equations, formulas, and more.
Post by Email - Post by Email is a way of publishing posts on your blog by email. Any email client can be used to send the email, allowing you to publish quickly and easily from devices such as cell phones.

Beautiful Math with LaTeX

LaTeX is a powerful markup language for writing complex mathematical equations, formulas, and more. Jetpack combines the power of LaTeX and the simplicity of WordPress to give you the ultimate in math blogging platforms.

To enable this feature, visit Jetpack → Settings → Writing in your site’s WP Admin. Scroll down to the Composing section and toggle on the Use the LaTeX markup language to write mathematical equations and formulas option.

Using LaTeX

To include LaTeX ( $\LaTeX$ ) 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

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

LaTeX Error

If your LaTeX code is broken, instead of the equation, you’ll see an ugly yellow and red error message.

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:

$\LaTeX&s=X$

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 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.

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

$\LaTeX$

LaTeX Packages

WordPress.com uses standard LaTeX with the following packages:

amsmath
amsfonts
amssymb

Privacy Information

LaTex is deactivated by default. You can toggle it on Jetpack → Settings → Writing page.
