I'm trying to beautify my program made with Quickly using CSS. I found documentation http://developer.gnome.org/gtk3/3.4/GtkCssProvider.html and very useful blog post http://erikos.sweettimez.de/2011/11/24/gtk-3-theme-style-your-applications-2/

According to the above I should be able to use ID selectors, for example:

#nameofmywidget {
    font: Ubuntu 12;

Unfortunately this does not work. Only working way for me is using:

GtkEntry {
    font: Ubuntu 12;


.entry {
    font: Ubuntu 12;

but it's to generic.

Apart from that I'm not able to change GtkEntry and GtkButton backgrounds. Any help much appreciated.


I found a way to change GtkEntry and GtkButton background colours. Instead of using:

GtkEntry, GtkButton {
    background-color: #ffffff;

I've used:

GtkEntry, GtkButton {
    background: #ffffff;

Can you post the code in the widget? –  jasmines Jul 3 '12 at 13:36

Load your .css file using that tutorial code Then on your widget do : self.sample_widget.get_style_context().add_class("sample_class")

Put this in the .css file :

GtkButton.sample_widget { color : #00FF00 }

Many thanks! It works! Although it should be GtkButton.sample_class { color : #00FF00 } –  mivoligo Jul 5 '12 at 12:22
Glad that I was able to help. –  Aleksandar Jul 5 '12 at 13:51

You can get more specfic with

GtkButton.name_of_button {
       background: red;

,that way only button widget "name_of_button" will be effected.

Thanks for the answer, but it does not work for me. –  mivoligo Jul 3 '12 at 18:29
Wrong. That coding means "all GtkButton with class name_of_button". –  jasmines Jul 4 '12 at 5:36


GtkButton#nameofmywidget {
    font: Ubuntu 12;

work? Howevere. please post your widget code too.
