I made my very own WordPress theme from scratch and I don't use a header nor a footer for it (so no header.php or footer.php files present). All of the important content is directly in the index.php file.
So I was wondering where I can put my meta tags in. Specifically this meta tag,
<meta name="viewport" content="width=device-width, initial-scale=1.0"/>
I'm currently making my theme responsive and so far, all my css media queries are not working at all.
Can I just put it in my index.php file or do I have to set up a function in the functions.php file?
Thanks for any help!
