I write on a variety of topics, only some of which it's appropriate to have mathematical typesetting for. To avoid triggering a math rendering engine on unrelated use of $purious dollar sign$, while activating it when $\text{necessary}\wedge\text{appropriate}$, I decided to restrict them to only elements with .language-mathjax. Here's how that's done (for v3):

MathJax = {
tex: {
inlineMath: [
['$', '$']
]
},
startup: {
elements: ['.language-mathjax']
}
};

I also recommend adding the following CSS to the admin-area with a userstyle or something:

.mce-content-body .language-mathjax {
background-color: peachpuff;
}

## One thought on “WordPress: Restrict MathJax to a class”
