Hello,

This issue is actually caused by your Joomla template which is enforcing a height of 16px on all the buttons, http://take.ms/nEnVa

To fix this, you can add the css codes below to reset the height of these buttons,

[gist]
body div#ed .btn-primary {
height: auto;
}

body div#ed .ed-navbar__o-nav li:before {
content: "" !important;
}
[/gist]

Thank you for the quick answer.
On the first screenshot there are two buttons ("Antwort...") the background of wich should be modified. How can I do this?

Regards

Richard

Hello Richard,

The css code that I have provided above will also fix the background on the list item on the toolbar.

You are most welcome Richard
