What happens if I don't put a <!DOCTYPE html> in my code? Will it make any major changes?
I\'m working on several projects with HTML, and sometimes I forget to put . Will it make any big or noticeable changes?

In HTML documents, browsers use a DOCTYPE in the beginning of the document to decide whether to handle it in quirks mode or standards mode.
// Tells the browser that we are using HTML5.If document type is not mentioned, browser will go to Quirks mode. Quirks mode depends upon the web browser version, If is older version then this will not support HTML5 tags (Example: header tag, footer tag, section tag,...)
To see the different between the Quirks mode and Standard mode visit : https://developer.mozilla.org/en-US/docs/Web/HTML/Quirks_Mode_and_Standards_Mode
If you want to try this one use the below code with and without
in your older browser like IE 8 or earlier
``//Note : In the above code src="give your local mp4 video link in your computer"
