bootstrap will follow a tick tag in the input box when the contents of the input box are filled correctly, but because I use input-group followed by a unit in some input boxes, there is a problem with the input. I would like to ask if there is any good solution
< div class= "form-group" >
<label class="col-lg-2 control-label"></label>
<div class="col-lg-4">
<div class="input-group">
<input type="text" class="form-control" name="building" id="building">
<div class="input-group-addon"></div>
</div>
</div>
<label class="col-lg-2 control-label"></label>
<div class="col-lg-4">
<div class="input-group">
<input type="text" class="form-control" name="landarea" id="landarea">
<div class="input-group-addon"></div>
</div>
</div>
