% For use with mathjax-3.html.
% For formatting pages using CBS with MathJax-3.
% When using Jekyll, include this file in a page by adding to the front matter:
% layout: cbs-mathjax
% or:
% layout: cbs-mathjax-local
% The macros support formatting all of CBS. The MathJax-3 rendering is
% compatible with the LaTeX rendering of articles that use cbs-latex.sty.
% The colors are specified using CSS, so that they can be changed according
% to the page background color.
% The configuration tex block should include:
% maxBuffer : 10 * 1024
% The output block should include:
% mtextFont: 'sans-serif'
% See the docs at:
% ???

\newcommand{\nobreak}{}
% \SHADE{MATH} can be defined to produce a shaded background to highlight
% inline MATH in running text:
\newcommand{\SHADE}[1]{#1}
% \STYLE{STYLE-NAME}{TEXT-OR-MATH} lets CSS determine the color of TEXT-OR-MATH,
% so that it can change when a web page changes between light and dark modes.
% STYLE-NAME should be either Key, PartVariable, Name, SyntaxName, SemanticsName,
% Language, or SectNumber.
% TO DO: Improve the style names!
\newcommand{\STYLE}[2]{\class{cbs-#1}{#2}}
% \KEY{text}, \STRING{text}, \ATOM{text}, \LEX{text} can be used in text or math.
% When the MathJax configuration includes mtextFont: 'sans-serif', \KEY{text}
% renders as slanted sans-serif, but \VAR{text} still renders in a serif font.
