In the registration forms both horizontal and vertical spacing become very large, I solved the problem by adding the margin-bottom: 10px; margin-right: -10px in each input, however , in the size sm and xm of the columns it loses the direct marge with this solution.
<div class="row">
<div class="col-sm-6 col-md-6 col-lg-6">
<div class="form-group form-float" style="margin-bottom:10px;margin-right:-10px">
<div class="form-line">
<label style="margin-bottom:-5px;">CNPJ*</label>
<input id="in_cpf_cnpj" name="cpf_cnpj" type="text" class="form-control" readonly>
</div>
</div>
</div>
<div class="col-sm-6 col-md-6 col-lg-6">
<div class="form-group form-float" style="margin-bottom:10px;margin-left:0px">
<div class="form-line">
<label style="margin-bottom:-5px">Inscrição estadual*</label>
<input id="in_rg_insc_estadual" name="rg_insc_estadual" type="text" class="form-control">
</div>
</div>
</div>
</div>
I also found this with a gambiarra face. Can you leave default for all inputs?
