I've never left a review before, but this add-on is so incredibly helpful that I felt it was worthy of a five-star review. It covers pretty much everything an amateur developer like me needs. It is like having a handy guidebook at your fingertips. The "Bonus" section is particularly useful. Wonderful job.
This addon is very useful for 'lazy' web developer and designer. :D Don't get me wrong please, I like your addon! Really useful and fast way to get modern designs in a few seconds. The code is correct and working good in all known browsers. Good job! Thanks for it!
Don't get me wrong, I like the idea and I can see by the code in the xpi that a lot of thought and work has gone into the design. I solved my problem by popping open the xpi and changing the values I needed to make it look right. Even though I could work out what was what, I might suggest a little more commenting in the code to make it easier to identify what's being worked on. I think you've done a fine job on a handy little tool and I intend on using it and following the development.
Hi! CSSsir works just with CSS properties and NOT with the html tags or CSS selectors (except TagCleaner tool). Selecors tab in Bonus contains only CSS tips partly taken from http://www.w3.org/TR/CSS2/selector.html
Any question about work of CSS selectors you can ask World Wide Web Consortium (W3C)
I strongly advise you not to use cyrillic alphabet in CSS selectors. Try to use standart id or class selectors in latin.
P.S. To solve your problem try charset "utf-8" in CSS files and
