问题描述:

Suppose, I have many formulae on the page.

I want to enclose each formula in `\large{}`

, i.e. `$x+1$`

becomes `$\large{x+1}$`

.

Is there any way I can do this with MathJax or I need to set skipstartup to true, manually add and then queue typeset?

Is there any way MathJax could fetch those formulae?

Thank you.

Answer is to use `prefilter`

```
<script type="text/x-mathjax-config">
MathJax.Hub.Register.StartupHook("TeX Jax Ready",function () {
MathJax.InputJax.TeX.prefilterHooks.Add(function (data) {
data.math = '\\large{'+data.math+'}';
});
});
</script>
```
