Any assistance will be appreciated.
I just installed eCSStender.  I tried using it in one of my own files
and border-radius didn't work.  I then copied some example code from
http://designshack.co.uk/articles/css/using-ecsstender-to-clean-up-your-css.
Note that the instructions say that you only need eCSStender.js and
eCSStenderBB.js.
The JavaScript files are at the same level as the html file.
Thanks,
Avram Baskin
