Add local scroll bar for long equations

[itskalvik]

Hi everyone!
I have some long equations in my posts that are getting cut off on the right side. Is there a way to add a local scrollbar to my MathJax equations?

I was told it can be done by add the following css rule to mjx-container elements: overflow-x: auto;

Can someone please point me to a tutorial that explains where I need to add the css rule? I would really appreciate any help with this 😄

Got it, just add the following to this file: assets/scss/custom.scss

.MathJax, .MathJax_Display {
overflow-x: auto !important;
overflow-y: hidden !important;
}
