I want to apply css to all class that starts with for example \'abcd-\' but I don\'t want to apply that css to class with name for example \'abcd-dontapply\'. Can I do this?
You can do that with proper css selectors: starts with selector would be like-
div[class^="abc"]:not([class="abc2"])
I have a sample jsfiddle for you: http://jsfiddle.net/8w65ffj0/1/
As mentioned in your question:
Don't add whitespace unnecessarily. The whitespace just before the :not is significant, i.e. it changes the meaning of the selector.
a[class^="abcd"]:not(.abcd-dontapply)
{
/* define CSS here*/
}
You can find all attribute selectors specifications here.
