How to center a set of html radio buttons in a fieldset with div

Question

I have a set of radio buttons and labels. The radio buttons precede the labels. I would like to center the set of them within a field set. I tried putting them in a div with display set to inline-block. Almost works, but one label gets bumped down to the next line.

My understanding was that giving a div display: inline-block would make it shrink-to-fit, but I'm getting the unexpected behavior you can see here (code below):

Is my only hope to manually set margins and stuff? Is there a way to understand why the div is shrinking just a bit too much??

Update... If I remove the right margin from the label (which is there to add space before the next radio button) then it fits. If, instead, I add margin-left to the button, I still have the problem.

<form>
<fieldset>
    <legend>Test</legend>
    <div>
        <input class="radio-input" type="radio" name="test" value="yes" />
        <label class="radio-label">Yes</label>
        <input class="radio-input" type="radio" name="test" value="yes" />
        <label class="radio-label">No</label>
        <input class="radio-input" type="radio" name="test" value="yes" />
        <label class="radio-label">Maybe</label>
    </div>
</fieldset>

.radio-label {
    float: left;
    margin-right: 3%;
}
.radio-input {
    float: left;
}
fieldset {
    text-align: center;
}
div {
    display: inline-block;
    margin: auto;
    border: 1px solid black;
}

Answer 1

Try this remove float left on your .radio-label and .radio-input and now define

display inline-block

As like this

.radio-label {
   display: inline-block;
    vertical-align: top;
    margin-right: 3%;
}
.radio-input {
   display: inline-block;
    vertical-align: top;
}

Similar to @Bart's solution, except, maintains other styling such as the spacing and the vertical alignment between labels and buttons. – Widera

Answer 2

Just remove all styles but text-align:center and you got it. No need to display: inline-block.

here's an updated fiddle:

.radio-label {}
.radio-input {}
fieldset {
    text-align: center;
}
div {}

Simplest solution, but does not keep radio labels spaced apart with margin. But gets to the point that all that is needed is to text-align the fieldset. Nonetheless, would cause problems if I had other elements in the fieldset, such as a text input, that I did NOT want centered. – Widera

@Widera all that can be easily achieved. If you have any question on how to do that, just answer with that information. you can have a div wrapping the elements you want centered and applying a class. you get the point. – Teleprinter

Answer 3

use this following css.

.radio-label {
  margin-right: 3%;  
}

fieldset {
    text-align: center;
}
div {
     display:inline;
        border: 1px solid black;
}
