System information (as much as possible)

Joomla! 3.7.0-rc2
OS: Linux Deepin 15.3
Kernel: 4.4.0-3-deepin-amd64
Google Chrome: 56.0.2924.76 (64 bit)
PHP: 7.0.12-2

Is this still valid in 3.7.4?

@dgt41 Grean backgroud confirmed on 3.7.4.

@ciar4n @C-Lodder can you take a look at this one? It looks like css related

background is defined in .input-append .active, .input-prepend .active selector.

@wojsmol I think the conflict comes from the search tools...

The issue simply comes from:

.input-append, .input-prepend {
    margin-bottom: 9px;
}

which is Bootstrap's CSS.

So the following LESS required to fix would be:

.js-stools-field-filter {
    .input-prepend,
    .input-append {
        margin-bottom: 0;
    }
}

@C-Lodder i guess there should be a background-color reset for the green background or not?

I have absolutely no idea what validation classes are being used in J3, so not sure if the green BG should be there or not.

Is there a particular reason why the active class is been added to these fields?

@ciar4n not that I can see but I also cannot see where it is coming from

@franz-wohlkoenig That PR adresses the colour, not the unecessary bottom margin. So this needs to be re-opened

reopen as stated above.

I added the code for the margin to the PR at #18231
