Adjust icone CSS form

Question

I have the following form

However, the H3 icon, from above, was OK, only the next titles I put, are on the side of the form, how to do to adjust?

HTML:

      <h3 class="titulos_cadastro"><i class="rt-icon2-waves"></i> Dados Profissionais</h3>

        <div class="col-sm-8">
            <div class="form-group">

Answer 1

Without your CSS it is difficult to give a 100% accurate answer. But in this test I did using display: inline-block; worked.

See the example below with the icons in the right place.

.rt-icon2-waves, .rt-icon2-photo {
    width: 24px;
    height: 24px;
    background-image: url(http://placeskull.com/32/32);
    display: inline-block;
}

<link rel="stylesheet" type="text/css" media="screen" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" />
