Typesetting with TeX\TeX. This is a list of TeX\TeX functions supported by Blot. It is sorted into logical groups.

    Blot can typeset $$\TeX$$. Use two dollar signs ($) to delimit the $$\TeX$$. You can use $$\TeX$$ in the middle of a sentence, or on its own line:

    f(x) = 2x^2 + 2/3

There is also support for {darray} and {dcases}. Acceptable line separators include: \\, \cr, and \\[distance]. Distance can be written with any of the units. The {array} environment does not yet support \hline.

The color function behaves like a switch.

F=ma\color{blue} F=ma \color{blue} F=ma
F=ma\color{#fc625d} F=ma \color{#fc625d} F=ma

Other color functions always expect the content to be a function argument.

F=ma\textcolor{forestgreen}{F=ma} \textcolor{forestgreen}{F=ma}
F=ma\textcolor{#fc625d}{F=ma} \textcolor{#fc625d}{F=ma}
A\colorbox{gold}{A} \colorbox{gold}{A}
A\fcolorbox{black}{gold}{A} \fcolorbox{black}{gold}{A}

For color definition, color functions will accept the standard HTML predefined color names. They will also accept an RGB argument in CSS hexa­decimal style.

One can stack font family, font weight, and font shape by using the \textXX versions of the font functions. So \textsf{\textbf{H}} will produce H\textsf{\textbf{H}}. The other versions so not stack, e.g., \mathsf{\mathbf{H}} will produce H\mathsf{\mathbf{H}}.

Units are proportioned as they are in TeX instead of CSS.

where: F = font size of surrounding HTML text10 pt\large \frac{\text{font size of surrounding HTML text}}{10\text{ pt}}
G = 1.21 by default, because TeX\TeX font-size is normally 1.21 × the surrounding font size. This value can be over-ridden by the CSS of an HTML page. For example, on this page, G = 1.0.

Rendering process

Blot uses KaTeX on the server side and does not require the visitor to enable JavaScript. However, it means that you cannot modify the behavior of the renderer. Blot uses the default configuration which is good in most cases. If you need to customize KaTeX or, perhaps, use MathJax or another rendering library, then first disable the server-side rendering in the settings of your site, then modify the template to add custom JavaScript. See developers section.
