I just built the docs using this change and it looks the same as it currently does. Am I missing something?

[1kastner]

@lmtierney when I was browsing the index.rst file on github directly, there was no syntax highlighting. See e.g. https://github.com/1kastner/selenium/blob/49c5380e4b992d84fe20b8adfddcb943becc84bb/py/docs/source/index.rst compared to https://github.com/SeleniumHQ/selenium/blob/master/py/docs/source/index.rst

As I only changed the docs, the failed builds are suspicious. At Travis I see it was a simple timeout and at AppVeyor the build crashes but so does the build of the master branch...

[lmtierney]

Yeah you can ignore the Travis errors.

The files in the repo that you pointed to are used to build the docs which are then hosted here:

@lmtierney If the docs even look beautiful in GitHub I think that is to be preferred, even though it is not a big improvement.

[lmtierney]

Ok... I'll leave it up to @davehunt to decide

Looks good, thanks @1kastner
