Line break tag

Question

I used <br> , </br> , <br/> all the three tags one at a time for breaking the line. The results were the same. How is this possible???
How could the computer depict the same meaning for all the three tags???

Answer 1

The br tag doesn't need to have an end tag. So you can write the three forms!
<br> = without end tag
</br> = end tag
<br /> = tag + end tag at once
