Support for 2.0

[brenwell]

Hey nice little package, if you get a minute it would be great to get support for 2.0

There appears to be some issues with opacity and a os notification warning saying something is wrong, but offers no other info

Thanks

quick fix, but can be better.

css: 
`    
    .term_fit.term_wrapper {
      opacity: 1 !important;
    }
`,
