Wordpress Question

If i get wordpress does that mean the templates are essentially the code for the website? Like i need to be able to easily access the main source code for my site to put the content locker code after the >head< tags is this really easy to do in wordpress?

Yes, you can do this even through Wordpress Admin as it has integrated theme code editor.

Install this WP plugin, you don't need to edit your theme code to paste the content locker.

If you do decide to go the route of editing your themes code, make sure you make a backup copy of the file you edited. That way if you bork something, you can just put the backup...well....back.

But if you are new to code and not really sur what you are looking at, the plugin route will be your best bet. Don't get discouraged though, learn to code and a lot of doors open!
