Hey @catherinewoodward this might be a bit more than you want to get into but I thought I’d toss it out as an option (and to anyone else really if they want to try it)…I set up WAMP on my windows computer and basically it turns it into a workable server. I can then store and run my files locally and access them through my browser with something like “localhost/someproject/index.html”
The directory system is just like a normal computer directory. So I can just make a new directory in the server’s main folder (www), put all my code files in there and then access it by a browser while the server is running.
From what I’ve used it for I know it can run html/css, js, php (in fact it comes built in with Apache and MySQL). You can put together databases with phpmyadmin and run wordpress installations, actually you can run pretty much all the major CMS’s with it. I’ve had drupal on there and joomla. It’s basically where I build and test all my prototype code and sites.
I’m not going to lie, the set up is pretty involved but not awful 
. I mentioned it to a fellow camper with links to what he would need: Apache Server and MySQL not Installing
Of course that’s all if you’re running a windows pc but fear not!
MAMP (for Mac’s): https://www.mamp.info/en/
LAMP (for Linux): https://www.lifewire.com/create-lamp-web-server-using-ubuntu-4135422
Just a heads up, I’ve never installed MAMP or LAMP so I can’t help you with those if you have any questions.
