Make button group that flows vertically to horizontally cleanly - css

Question

I've used a normal bootstrap 3 button group in a size one column, e.g.
<div class="col-sm-1">
<div class="btn-group">
<button class="btn btn-default"><span class="glyphicon glyphicon-home"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-circle-arrow-left"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-volume-down"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-volume-up"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-off"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-zoom-out"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-zoom-in"></span></button>
</div>
</div>
This is vertical when there is space, but when it drops to a new row it becomes horizontal. My only problem is that when vertical it looks a bit odd. I've tried playing with the CSS to no avail, does anyone have advice? I don't mind making it fully square so horizontal/vertical are similar, but my efforts to do this have not worked

Answer 1

If fully square buttons are ok to you, something like this should work:
CSS:
#group button:first-child, #group button:last-child {
border-radius: 0;
}
#group button:first-child {
margin-left: -1px;
}
HTML:
<div class="col-sm-1">
<div id="group" class="btn-group">
<button class="btn btn-default"><span class="glyphicon glyphicon-home"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-circle-arrow-left"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-volume-down"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-volume-up"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-off"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-zoom-out"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-zoom-in"></span></button>
</div>
</div>

Answer 2

I had created something like this before.
DEMO: http://jsbin.com/vahaq/1/
Assumes vertical on 768px and up, which is what it is, so I've just modified the styles below that min-width.
HTML (same as yours but with btn-group-vertical and btn-group-custom)
<div class="col-sm-1">
<div class="btn-group-vertical btn-group-custom">
<button class="btn btn-default"><span class="glyphicon glyphicon-home"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-circle-arrow-left"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-volume-down"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-volume-up"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-off"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-zoom-out"></span></button>
<button class="btn btn-default"><span class="glyphicon glyphicon-zoom-in"></span></button>
</div>
</div>
This is more elaborate as it kicks in and kicks off for really good responsiveness:
#media (max-width:299px) {
.btn-group-vertical.btn-group-custom > .btn {
float: left;
width: auto;
width: 25%;
min-height: 50px;
min-width: 50px;
margin-top: -1px!important;
}
.btn-group-vertical.btn-group-custom .btn + .btn {
margin-left: -1px;
margin-top: 0;
}
.btn-group-vertical.btn-group-custom > .btn:first-child {
margin-top: 0;
margin-left: -1px;
border-radius: 0;
}
.btn-group-vertical.btn-group-custom > .btn:last-child {
border-radius: 0
}
}
#media (min-width:300px) and (max-width:767px) {
.btn-group-vertical.btn-group-custom > .btn {
float: left;
width: auto;
border-top: 1px solid #ccc;
}
.btn-group-vertical.btn-group-custom .btn + .btn {
margin-left: -1px;
margin-top: 0;
}
.btn-group-vertical.btn-group-custom > .btn:first-child {
border-radius: 4px 0 0 4px
}
.btn-group-vertical.btn-group-custom > .btn:last-child {
border-radius: 0 4px 4px 0
}
}
