css label width not taking effect

Question

I have a generic form, which I'd like to style to align the labels and the input fields. For some reason when I give a width to the label selector, nothing happens:

HTML:

<form id="report-upload-form" method="POST" action="" enctype="multipart/form-data">
    <p>
        <label for="id_title">Title:</label> 
        <input id="id_title" type="text" class="input-text" name="title"></p>
    <p>
        <label for="id_description">Description:</label> 
        <textarea id="id_description" rows="10" cols="40" name="description"></textarea></p>
    <p>
        <label for="id_report">Upload Report:</label> 
        <input id="id_report" type="file" class="input-file" name="report">
    </p>
</form>

CSS:

#report-upload-form {
    background-color: #316091;
    color: #ddeff1;
    font-weight:bold;
    margin: 23px auto 0 auto;
    border-radius:10px;
    width: 650px;
    box-shadow:  0 0 2px 2px #d9d9d9;
}

#report-upload-form label {
    padding-left:26px;
    width:125px;
    text-transform: uppercase;
}

#report-upload-form input[type=text], 
#report-upload-form input[type=file],
#report-upload-form textarea {
    width: 305px;
}

Output:

What am I doing wrong?

Answer 1

Do display: inline-block:

#report-upload-form label {
    padding-left:26px;
    width:125px;
    text-transform: uppercase;
    display:inline-block
}
