General What is the template calling?

Hi, I'm new to website building but can code in almost any language once I learn the syntax. I downloaded the "charity" template and have edited the .css file to make the .html file look like I want.

I can't figure out how to change the content of the .html though. What is the content calling? Is it calling another file that I didn't get? From what I understand, a .css file is the template that each webpage will call. Is this correct? How do I call the .css file? Is it simply
<link rel="stylesheet" href="style.css" media="screen" /> Because if I only put this I get the correct background and text color but my navigation bar and header image is completely left off.

Also, I have read that the .psd file is mainly for Photoshop and can edit the images and such. I don't have Photoshop so I haven't been able to open this but I edited the images using paint and that worked just fine. Is that okay?

Thank you for your help! ~Susan

 

When I edited the pictures I did change sizes. The new images work just fine in the new .css file. When I try to call the .css file from my own .html file then my .html file doesn't look like the .css file. It looks like a blank page with the same background color and some text but no formatting from the .css.

 

Got it!!!!!!!!

Wooot woot! I got it... Thanks for the Basic Primer...

Right click on index.html and open with notepad - or as I love to use, UltraEdit.

Ishkey, you are a genius.
