Summary0012352: Add my own css code without modifying default.css

There is css/default.css which is delivered with Mantis.
In config file I found variable "$g_css_include_file" to use other css file.

First thought was "Cool, I can use default.css and use $g_css_include_file to append my css code from separate file".

But behaviour is different because when I use $g_css_include_file then only this file is used and default.css is ignored.
I verified this statement by checking html header.

So please add the posibility to add own css code without touching default.css.

Every time I update Mantis I have to diff old and new default.css to merge my changes into new default.css.
So I am looking for an easier way.

Additional Information

As a temporary workaround you can just place @import url('default.css') to the top of your custom CSS file.

Thanx dhx for this valuable hint.

Now I can use default.css AND my custom css.

You can close this issue if you want.

Thanks for the feedback.

I'll probably leave this issue open as there is a valid feature request here for a configuration option that is essentially an array of additional CSS files to include.

Using @import is usually frowned upon due to performance reasons (browsers have to wait for custom.css to load before it can start loading default.css - ideally both files should be downloaded in parallel by the browser).

Hello dhx,

your arguments sounds very comprehensible.

It would be a much better solution to have configuration options for that.

Personally I can live with @import in our intranet. No performance problems ;-)

Hello Kirill,

we run stable 1.2.3 here.
I cannot apply your patch against this version.
There is no function require_css in html_api.php here.

Could you provide a patch against 1.2.3?

reporter   ~0039359

You can close issue.

The provided patch is actually against master branch (1.3.x)

Dropping target version - reporter states we can close issue - i'm inclined to leave it open for now (sorry rake for any email notifications on this) just so we can implement something when dealing with theming/redesign. It's already got the redesign tag so we should pick it up then.

Currently, any custom CSS or JS file can be included with a plugin that uses the EVENT_LAYOUT_RESOURCES.
