relative file path to fonts in css file - html

Question

I have a stylesheet that is referenced in the header:
<link href="./css/stylesheet.css" rel="stylesheet">
All of the css works in it except this specific code:
#font-face {
font-family: 'icomoon';
src: url('fonts/icomoon.eot?hsw0h3');
src: url('fonts/icomoon.eot?hsw0h3#iefix') format('embedded-opentype'),
url('fonts/icomoon.ttf?hsw0h3') format('truetype'),
url('fonts/icomoon.woff?hsw0h3') format('woff'),
url('fonts/icomoon.svg?hsw0h3#icomoon') format('svg');
font-weight: normal;
font-style: normal;
}
When I put the above #font-face CSS in the page above where the icons are being shown it works but when I put it in the CSS file it stops working. I finally found out that this was likely due to the file path not being correct.
Here is the file structure:
Looking at this article (https://css-tricks.com/quick-reminder-about-file-paths/) it looks like I should either use:
url('/fonts/icomoon.ttf?hsw0h3')
url('../fonts/icomoon.ttf?hsw0h3')
to go back to the root and then into the fonts folder. But the icon still is not rendering from the CSS file.
What am I doing wrong and how do I fix it?

Answer 1

URLs in CSS files are relative to the CSS file.
url('fonts/icomoon.eot?hsw0h3'); means http://example.com/css/fonts/icomoon.eot?hsw0h3, but your screenshot of your directory structure shows you need http://example.com/fonts/icomoon.eot?hsw0h3.
Add ../ or /

Answer 2

../ need to be added before the path to move up one folder in hierarchy (../../path) to move two folders up in hierarchy

Answer 3

Consider describing the font sources individually without any version specification (I guess) like,
#font-face {
font-family: 'icomoon';
src: url('fonts/icomoon.eot');
src: url('fonts/icomoon.eot') format('embedded-opentype');
src: url('fonts/icomoon.ttf') format('truetype');
src: url('fonts/icomoon.woff') format('woff');
src: url('fonts/icomoon.svg') format('svg');
font-weight: normal;
font-style: normal;
}
Alternatively, you may also remove the format specification and let the browser to determine automatically, if problem still persists.
