Several elements with the same ID responding to one CSS ID selector
Below is the example code that I was testing and I got confused. Every one says that we can use or we should use only one time per id, but I have testes using using it multiple times but its giving me the correct output.
What should I do?
It's kinda working same like class for me in this example
code:
<html>
<head>
<style>
#exampleID1 { background-color: blue; }
#exampleID2 { text-transform: uppercase; }
</style>
</head>
<body>
<p id="exampleID1">This paragraph has an ID name of "exampleID1" and has a blue CSS defined background.</p>
<p id="exampleID2">This paragraph has an ID name of "exampleID2" and has had its text transformed to uppercase letters.</p>
<address id="exampleID1">

<blockquote id="exampleID1">
Here is a long quotation here is a long quotation here is a long quotation here is a long quotation here is a long quotation here is a long quotation here is a long quotation here is a long quotation here is a long quotation.

</body>
</html>
Please see the above code and answer me that why we should not use id selector two times in a page while its working fine.

An id must be unique in a page. Use a class if you want to describe a group of elements.

You are making an error and depending on every browser that will ever view the page to compensate for it. You can't be sure they all will.
