Bootstrap input-group-addon Not Vertically Aligned

Question

I'm using the following markup with Bootstrap:

<div class="row">

    <label class="col-md-4">Date of Completion of Checklist</label>

    <div class="col-md-4">
        <div class="input-group">
            <input type="text" class="form-control datepicker">
            <span class="input-group-addon glyphicon glyphicon-calendar"></span>
        </div>
    </div>

</div>

I have some of my own CSS in a separate file, including:

.form-control {
    border-color: #000;
    border-radius: 0;
    box-shadow: none;
}

.form-control:focus {
    border-color: #009966;
}

label {
    font-weight: bold;
    margin-top: 8px;
}

.input-group-addon {
    background: #fff;
    border-color: #000;
}

However, even when I remove my whole custom stylesheet, I am still presented with this vertical alignment issue you can see below:

It looks like it's 1 pixel off what it should be. I've tried setting the positioning to relative and set bottom: 1px however it doesn't appear to budge.

If I remove the vertical-align property it completely messes up the look of it.

Does anyone have an idea what could be causing the problem?

Answer 1

.glyphicon {
    top: 1px;
}

change this to top:0px; or add style="top:0px;" top your span

Answer 2

Try some thing like this input-group-addon and place span above input

<div class="input-group">
    <span class="input-group-addon" id="basic-addon1"><i class="fa fa-calendar"></i></span>
    <input type="text" class="form-control datepicker" aria-describedby="basic-addon1">
</div>

Answer 3

Changing your html to this fixes it:

<div class="row">

    <label class="col-md-4">Date of Completion of Checklist</label>

    <div class="col-md-4">
        <div class="input-group">
            <input type="text" class="form-control datepicker"/>
            <span class="input-group-addon"><i class="glyphicon glyphicon-calendar"></i></span>
        </div>
    </div>

</div>

i have moved the glyphicon glyphicon-calendar class to an <i> inside your span, which now aligns all correctly.
