…ens view. (alshedivat#3302) This PR fixes an issue where long MathJax formulas in blog posts overflowed horizontally and broke the layout. * Added a small CSS rule to make MathJax formulas horizontally scrollable instead of overflowing. * Now, when a formula is wider than the container, users can scroll horizontally without the page layout getting messed up. **SCSS changes:** ```scss mjx-container[jax="CHTML"][display="true"] { overflow-x: auto; } ``` **Testing:** Verified that: * Long formulas no longer push the layout wider than the viewport. * Short formulas render as before.
