#### What Is Copyleft?

Here are a few sources to read generally what copyleft is:

  * [Richard M. Stallman's essay on copyleft at gnu.org](https://www.gnu.org/copyleft/)

  * [The Wikipedia entry on Copyleft](http://en.wikipedia.org/wiki/Copyleft)

* copyleft.org logo clipped by a few pixels on the right in Firefox, but goes away at certain magnifications, not present in Chromium. Seems related to svg. Getting rid of the svg and just always displaying bitmap fixes.

   * I think the above was merely a width/height setting issue, which appears fixed now.  Can you confirm?

      * It isn't fixed. Seems Firefox has some long term problems with unwanted SVG [clipping](https://bugzilla.mozilla.org/show_bug.cgi?id=1056949). I will try to reproduce and file.

      * I gave up and did this.  I don't get why <svg> doesn't work.  WTF?

        It worked in every browser I tested.

I think this is a WONT_FIX:

   * I'm going to ask Karen what she thinks about this.  I don't really care,

     and wonder if it's better that way for branding.  I'll leave it as is

     for now.

      * Make sure you look on a small screen device.
