just search for the C class name, e.g. /GtkButton/ https://developer.gnome.org/gtk3/stable/GtkButton.html
OK, found the page, but I did not find CSS things like "background-color".
in CSS. either add a line /background-image: none/ or use the shorthand /background:/ instead of /background-color:/ as that will achieve the same effect
OK, my understanding is that: css_provider->load_from_data("button {background-image: none;} button {background-color: #ff0000;}"); can be reduced to: css_provider->load_from_data("button {background: #ff0000;}"); with the same effect. I am right? But I still can't find that in the docs. What I see in the doc you link me to is: "GtkButton has a single CSS node with name button. The node will get the style classes .image-button or .text-button, if the content is just an image or label, respectively. It may also receive the .flat style class. Other style classes that are commonly used with GtkButton include .suggested-action and .destructive-action. In special cases, buttons can be made round by adding the .circular style class." But here I can't see something like "background-image" or " background-color:" or something. Maybe there is some other page which documents the "style class .text-button". But that page is not linked nor I can find it. Sorry again! But I want to be able to find the information my self :-) I can't believe that it is so hard to get the right links!
