What do you mean when you write in <meta charset="utf-8"> ?

You're telling the browser what character set you're using, so it can better render the text on screen.

The "meta" element essentially just means "some information about this document" so you can set various properties having to do about the document and its contents, but they're not directly a part of the document.

Here's more information than you need right now but it's probably going to be more digestable than the venerable 2003 rant on The Absolute Minium Every Software Developer... you might get directed to when asking this question.

Hello Itai Shin Also the literal translation here is that the character set or charset should be utf-8, or universal character set transformation format, eight bit. This is what the attribute means Gavin Ralston, he gives a good answer, in what it dose in the browser

I hope this help you David
