See bug 32123 for a bunch of info about fixing these portal pages; some have been cleaned up, others need to be done still.

See bug 35704

It's better as now the table is horizontally scrollable but still messy.

Several problems:

• Section toggling is not enabled. For some reason content of a section appears as a div outside the .content_block div rather than inside it
• There seems to be a need for a PortalTemplate to take away the need for inline styling

So I've cleaned up lots of portal pages [1,2,3]

I think next step is to get a list of all pages which have known bad styles
To do this we should download one of the latest dumps [4] and grep them for the following known patterns:
float:left; width:60%
float:left; width:51%;
float:right; width:48%
and then edit those articles so that they use classes instead.

Gabrielle Wicke has several node grepping tools [4] that will help us do this
I'll report back with a list of bad pages so we can clean these up.

Nice, but hard work. I wonder if we should stir up some community help, as we will shortly do with the default switchover of the sister projects?

Here is a list of effected pages on English Wikipedia:

Please help clean these up to close this bug.

Added fix to MobileFrontend stylesheet https://gerrit.wikimedia.org/r/#/c/10414/

Another example of a page with an inline style problem:
http://en.m.wikipedia.org/w/index.php?title=New_Haven_Line

$("[style]").removeAttr("style") fixes it
Haven't got time right now to explore this further

All portal pages are now fixed via a grease monkey script
