What is this?

I have been looking around to find what this means

what is <meta http-equiv=“Content-Type” content=“text/html;charset=utf-8”>

Must I include a DOCTYPE to go with above or not. I am trying out Flux 3 with Coda. Please advise me

It depends upon what you are planning on writing; I assume HTML 4.01 and that META http is defining a character encoding of UTF-8. Obviously character encoding is mandatory but there are various ways to achieve it. If you are writing valid HTML 4.01 then using a DOCTYPE is sensible.

Its the old way of telling the browser you’re using UTF8

And yes, use a doctype whatever version of HTML your using. It stops IE from slipping to quirks mode

meta tag is used to give information
the above meta tag tells the browser that the type of the content on the webpage is
text/html and its charset is utf-8
As stated above use doctype to make declarations about the web document
