And, to clarify further, the selector for elements with both 'btn' &
'px' classes[1] is '.btn.px'. Note that there's a dot before both
class names. There's also no space--'.btn .px' would select for an
element with classname 'px' inside of another with classname 'btn'.
Remember that jQuery's classname and ID selectors mirror those found
in your stylesheets, not your element attributes.
[1] Of course, either '.btn' or '.px' would work, also but '.btn.px'
is what's required to narrow it down to elements with both.
