Equations overflow in smartphone

The title is self explanatory: Equations that seem correct in desktop overflow in phones. Why this happens? Because the size of the characters is the same even thought in phones the size of the container decreases hence the equation just overflows.

The way to fix it would be to make the size of the equation adaptable so the size decreases as it reaches the limit of the webpages.

In desktop happens the same; if you write a really long equation it will just overflow. Again, is it possible to:

1. Automatically create linea break
2. AUtomatically decrease size of characters if limit is reached

I know this question should be to MathJax itself, this is just a plugin etc… I just ask if it is possible to do this with this plugin at this date.

Thanks!
