My input fields render inline on IE, but on new lines in Chrome and Firefox. How can I fix that?

Question

What do I need to change to make Chrome and Firefox render the same way as Internet Explorer? My first idea was to use CSS calc(), but I still need to support IE8.

I have the following CSS:

* {
    box-sizing: border-box;
}

.Width300
{
    width: 300px;
    padding: 5px;
    border: black 1px solid;
}

.Field
{
    white-space: nowrap;
    min-height: 26px;
    padding: 1px 0;
}

label
{
    float: left;
    display: inline;
}

input
{
    display: block;
    width: 100%;
}

.LabelSize100 .Field
{
    margin-right: 100px;    
}

.LabelSize100 label
{
    width: 100px;
}

.LabelSize100 input
{
    margin-left: 100px;
}

and the following HTML:

<div class="LabelSize100 Width300">
    <div class="Field">
        <label>test:</label>
        <input type="text" />
    </div>
    <div class="Field">
        <label>test:</label>
        <input type="text" />
    </div>
</div>

and the result is totally different in IE/Chrome and FF:

Answer 1

Just set display:inline-block; to <label> and <input>

CSS

label
{
    float: left;
    display: inline-block;
}

input
{
    display: inline-block;
    width: 100%;
}

.LabelSize100 input
{
 // Remove margin-left
}

Note: remove margin-leftfrom <input>
