XF 1.5 apply custom css code globaly throughout all themes?


Active member
i wish to place global change to every theme i have installed on my site and any future new themes that get installed, now i would usually edit the master style extra.css but last time i put something in there it got erased by updates or re-importing the core master data..

is there another template i can target? preferably a css template that loads in with every page.

also when I try to do via Regular expression on EXTRA.CSS

Find: /^.*$/s (I'm not good with these I just copied this from some other add-one)

and replace with this:

.fa {
    font-family: FontAwesome !important;
load order 10 (maybe change different load order?) - some 1 explain load order in detail 4 me?

but then this break my custom CSS in the extra.css for 1 of my themes:

.nodeList .categoryStrip .nodeDescription {
    color: orange !important;
    font-size: 10px !important;
    text-shadow: 0 0 10px black, 0 0 13px black, 0 0 15px black !important;
is now broken, is there a way to get around this? is there something I can globally edit without breaking any of my other css?

maybe expression wrong? any know how to target a blank page?
which the built in TMS had a simple inject mode function to inject any code you want at the bottom of what ever template you are targeting.

The master style is the only one which will affect all others.

You could consider creating an add-on which will apply a template modification (to the master style) which will subsequently apply to all styles.
