] | I'd suggest you have a look at this article by Paul Irish from 2009 named [Bulletproof @font-face syntax](http://www.paulirish.com/2009/bulletproof-font-face-implementation-syntax/)
It explains very well and in all detail how to get webfonts up and running across all (or at least all capable) browsers. | Another way is to use `link` tag to load the CSS. Then define the font in custom CSS.
Example:
```
<link href='http://fonts.googleapis.com/css?family=Abel' rel='stylesheet' type='text/css'>
<style type="text/css">
body {
font-family:'Abel',Sans;
}
</style>

1,003,201 | Is there a way to list runtime-only (i.e. no `--permanent`) changes in firewalld? I would like to see a diff in my configuration to make sure no change will get lost in case of a `--reload`. | 2020/02/15 | [

] | as far as I can see no tool that offers you that possibility, but you can create it yourself.
I add a runtime acl to port 54/tcp:
```
# firewall-cmd --add-port=54/tcp
```
Then I can save the runtime rules to a file:
```
# firewall-cmd --list-all > /tmp/runtime_rules
```
And I save the permanent rules to another ... | I'd like to propose a one-liner alternative usable in a bash shell:
```sh
diff -u <(firewall-cmd --list-all --permanent) <(firewall-cmd --list-all)
