Question

In the Ubuntu GTK Eclipse Juno theme, the selected tabs have a grey bottom border. I would like to remove this border. How can I do this?

I am NOT asking how to create, edit, or modify an eclipse theme. I am looking for the specific CSS styles required to remove the border.

Here is a screenshot of the selected tab with the border in question:

See that pesky grey border under Tab3? Yes. What CSS can I use to remove that border?

I found this:

http://hwellmann.blogspot.co.uk/2012/06/fixing-editor-tab-fonts-in-eclipse-juno.html

which explains how to get an E4 CSS editor and also says the change needed is:

.MPartStack {
    font-family: "Droid Sans" ;
    font-size: 9;
    swt-simple: false;
    swt-mru-visible: false;
}

which works for me.

The file /eclipse/plugins/…/e4_default_gtk.css did not change – I eventually found:

$HOME/.e4css/e4_default_gtk.css

which does have the updated CSS.
