html - Centering 2 elements inside Bootstrap column -


so if have 1 element, in case button, add .center-block class element , centered.

<div class="form-group">     <div class="col-sm-4 col-sm-offset-4">         <button type="submit" class="btn btn-primary center-block">element 1</button>     </div> </div>

but if have 2 elements? tried wrap them in div , added .center-div class so:

html:

<div class="form-group">     <div class="col-sm-4 col-sm-offset-4">         <div class="center-div">             <button type="submit" class="btn btn-primary">element 1</button>             <button type="submit" class="btn btn-primary">element 2</button>         </div>     </div> </div>

css:

.center-div {     display: inline-block;     margin-right: auto;     margin-left: auto; }

.center-div same .center-block except used display: inline-block; instead of display: block; fits contents size.

sadly doesn't work. unless change display: block; , assing fixed width 200px.

what missing here?

margin right , left set auto works if width of element fixed. center-div inline-block, need text-align: center property on container.

<div style="text-align: center">     <div class="center-div">         <!-- inner elements -->     </div> </div>

i used style attribute convenience in example
