Positioning Radio Buttons and Labels on the Same Line

In HTML forms, aligning radio buttons and their associated labels on a single line can be challenging. To achieve this, several CSS techniques can be employed.

The suggested HTML structure positions the label and input elements:

<label for="one">First Item</label>
<input type="radio" id="one" name="first_item" value="1" />

To align them horizontally, add the following CSS rules:

label {
  float: left;
  clear: none;
  display: block;
  padding: 0px 1em 0px 8px;
}

input[type=radio],
input.radio {
  float: left;
  clear: none;
  margin: 2px 0 0 2px;
}

This positions the label and radio button next to each other. To ensure that multiple radio buttons are aligned on the same line, use the following markup:

<fieldset>
  <div class="some-class">
    <input type="radio" class="radio" name="x" value="y" id="y" />
    <label for="y">Thing 1</label>
    <input type="radio" class="radio" name="x" value="z" id="z" />
    <label for="z">Thing 2</label>
  </div>
</fieldset>

With the appropriate CSS rules, the radio buttons and labels will be aligned on the same line.
