in the following snippet, how come the strong selector overrides the id selector? Isn't an id selector considered more specific, thus having priority?
<!doctype html>
<html>
<head>
<title>Sample document</title>
<style>
strong{color:red;}
#abc {color:blue;}
</style>
</head>
<body>
<p id="abc">
<strong>C</strong>ascading
<strong>S</strong>tyle
<strong>S</strong>heets
</p>
</body>
</html>
