why don't we need to close the meta tag like the other ones ?

Hi Raghav and Welcome to Treehouse.

In HTML (and a few other languages), there will be self-closing (or "Empty") tags.

For an in-depth explanation and some examples, please see this MDN Documentation.

Keep Coding! :)

Hey Raghav!!

I'm sorry to be "that guy". I looked on the web to help find an answer to your question. Here's what I found.

http://stackoverflow.com/questions/19506028/do-you-need-to-close-meta-and-link-tags-in-html

*"In XHTML, XML rules apply, so every element, without exception, must have both a start tag and an end tag, but the same tag may be used for both roles if the element content is empty,

e.g. <meta name="foo" content="bar"/> 

as short for

<meta name="foo" content="bar"></meta>.

If you violate this when serving a document with an XML (XHTML) content type to a conforming browser, then your document is not displayed at all; an error message is shown instead.*

When using XHTML server with HTML content type (Content-Type: text/html), as XHTML documents almost always are on the web, then browsers will actually apply the non-XHTML HTML rules.

To summarize:

+normally, use just

<meta ...>

with no

/

+if you are really using XHTML in a context where XHTML parsing is actually applied, play by XML rules (and make sure you know them)

+if your boss tells you to write ```<meta ... />

, do so; it’s not useful, but it causes no harm (except if you try to validate e.g. agaist HTML 4.01 doctype)."*

I Hope this helps!!!

This Are empty tags/ Stand alone tags, so there is no need to close them, In future you will encounter more empty tags like <img> i.e for inserting image or <hr> for adding a horizontal line
