KaTeX is a TeX rendering library — put simply, it processes TeX and produces correctly formatted text. It can be used for chemistry, math, and quantities.
The following parser tags are supported:
<chem><ce><math><quantity><tex>
Chemistry
Refer to the mhchem for KaTeX guide. (\ce{})
Some example inline chemistry: <chem>\ce{^{235}_{92}U -> ^{4}_{2}He + ^{231}_{90}Th}</chem>
Some example inline chemistry: \ce{\ce{^{235}_{92}U -> ^{4}_{2}He + ^{231}_{90}Th}}
<chem mode="display">\ce{^{235}_{92}U -> ^{4}_{2}He + ^{231}_{90}Th}</chem>
\ce{\ce{^{235}_{92}U -> ^{4}_{2}He + ^{231}_{90}Th}}
<chem mode="display" fleqn>\ce{^{235}_{92}U -> ^{4}_{2}He + ^{231}_{90}Th}</chem>
\ce{\ce{^{235}_{92}U -> ^{4}_{2}He + ^{231}_{90}Th}}
Math
Refer to the KaTeX supported functions page.
<math mode="display">x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}</math>
x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}
Quantities
Refer to the mhchem for KaTeX guide (\pu{})
The weight of an apple is around <quantity>100 g*N/n\Omega</quantity>.
The weight of an apple is around \pu{100 g*N/n\Omega}.
The weight of an apple is around <quantity>100 A*B/C2/D-4</quantity>.
The weight of an apple is around \pu{100 A*B/C2/D-4}.
