I have seen Commented CSS in my PHP page enclosed within <!-- -->
like
<style type="text/css">
<!--
body { }
...
-->
</style>
when I was optimizing my code then I deleted those commented CSS code from my page,
but after deleting, layout of that page has been disturbed.
when I again paste those commented CSS , it was working fine??
please tell me the reason and how does it possible that CSS is applying despite of comments
