Padding issue + Issue replying to my own post?

firstly regarding the actual issue

wanted to reply to this post -

Thanks Vinod,

That worked :slight_smile:

would you also be able to help me add a 5mm padding on the left and right of those pages : page-id-205, page-id-9, page-id-11

im currently using this but it seem to have no effect?

.symple-column{padding: 0 20px}

Secondly for some reason i got an error message when replying to my last post see attached.
