I still think equation numbers on the left is a mistake. Ideally, for smaller screens it would split across multiple lines. Or, it could choose the positioning based on screen size. For me, MathJax can't render my equations. I use some techniques to get a vector with an arrow on the bottom. Two commands I used all throughout my thesis are: \def \rV#1{\hbox{$#1$\kern-0.38em\lower0.85em\hbox{$\vec{}\,$}}\,} and \def \Vec#1{\hbox{$#1$\kern-1.0em\lower0.4em\hbox{${\scriptstyle \rightarrow }$}}} These won't work in MathJax (understandably).

Even careful hand-tuning with help from the breqn package can often look pretty bad. > Two commands I used all throughout my thesis are: At the risk of turning this into TeX StackExchange, I just want to point out that these kerning manipulations are entirely possible in MathJax. The problem is that, maddeningly, they chose to have non-math commands like kern and lower work exclusively in math mode, and not outside one like in a hbox. Therefore, if you change your second command to something like this: $a \kern-1em\lower0.4em\hbox{$\scriptstyle \rightarrow$}$ then it will work in MathJax. Of course, this would then break in regular TeX because you're not supposed to use kern and lower in math mode. I keep myself sober by remaining optimistic about a potential overhaul in the MathJax latex processing code. In the meantime, I think we would benefit from a stopgap service that renders these things in an actual TeX engine running on a server into high-res PNG (easy) or SVG (doubtful). There's been quite a resurgence in effort to make latex rendering into a scaleable web service lately. I'd love to collaborate with someone from, say, ShareLaTeX on that, if possible.

  That's awfully annoying of MathJax because you need two separate versions of the LaTeX, one for MathJax and another for LaTeX output. I know that there's dvisvgm for SVG output from DVI. I think there's also a tex2svg. Also, there's LatexRender-ng. So, there's a number of tools for SVG output.
