Prevent text from wrapping under a checkbox

This seems to work:

http://jsfiddle.net/7WmGr/5/

I gave the label a margin-left of 18px and the checkboxes a margin-left of -18px.

Seems to work in Chrome & IE9.

div.right {
  width: 598px;
}

form#updateProfile fieldset label {
  display: block;
  margin-bottom: 5px;
  font-size: 16px;
  float: left;
  width: 30%;
  margin-left: 18px;
}

form#updateProfile fieldset label input[type='checkbox'] {
  margin-left: -18px;
}

<div class="right">
  <form id="updateProfile">
    <fieldset class="checkboxes">
      <p>4. What is your favorite type of vacation?</p>
      <label><input type="checkbox" name="vacation" value="Ski Trips"> Ski Trips</label>
      <label><input type="checkbox" name="vacation" value="Beach Visits"> Beach Visits</label>
      <label><input type="checkbox" name="vacation" value="Cruises"> Cruises</label>
      <label><input type="checkbox" name="vacation" value="Historical and educational trips"> Historical and educational trips</label>
      <label><input type="checkbox" name="vacation" value="Yachting"> Yachting</label>
      <label><input type="checkbox" name="vacation" value="Road Trip"> Road Trip</label>
      <label><input type="checkbox" name="vacation" value="Spa Weekend"> Spa Weekend</label>
      <label><input type="checkbox" name="vacation" value="Bed and Breakfast"> Bed and Breakfast</label>
      <label><input type="checkbox" name="vacation" value="Stay home and relax"> Stay home and relax</label>
      <label><input type="checkbox" name="vacation" value="Gambling Trips"> Gambling Trips</label>
      <label><input type="checkbox" name="vacation" value="Volunteer"> Volunteer</label>
    </fieldset>
  </form>
</div>

One option would be something like this.

form#updateProfile fieldset label{
    display: block;
    margin-bottom: 5px;
    font-size: 16px;
    float: left;
    width: 30%;
    padding-left: 3%;
    position: relative;
}

input {
    position: absolute;
    left: -5px;
}

The way I tend to do it is different, which is not wrapping inputs with labels, rather doing something like

<input id="ski-trips" type="checkbox" name="vacation" value="Ski Trips"><label for="ski-trips">Ski Trips</label>

which then allows for easier styling.

Here is an example of that way: http://jsbin.com/otezut/1/edit

But either way would work.

The simplest option

HTML:

<form id="updateProfile">
    <fieldset class="checkboxes">
        <p>4. What is your favorite type of vacation?</p>
        <label><input type="checkbox" name="vacation" value="Ski Trips"> Ski Trips</label>
        <label><input type="checkbox" name="vacation" value="Beach Visits"> Beach Visits</label>
        <label><input type="checkbox" name="vacation" value="Cruises"> Cruises</label>
        <label><input type="checkbox" name="vacation" value="Historical and educational trips"> Historical and educational trips</label>
        <label><input type="checkbox" name="vacation" value="Yachting"> Yachting</label>
        <label><input type="checkbox" name="vacation" value="Road Trip"> Road Trip</label>
        <label><input type="checkbox" name="vacation" value="Spa Weekend"> Spa Weekend</label>
        <label><input type="checkbox" name="vacation" value="Bed and Breakfast"> Bed and Breakfast</label>
        <label><input type="checkbox" name="vacation" value="Stay home and relax"> Stay home and relax</label>
        <label><input type="checkbox" name="vacation" value="Gambling Trips"> Gambling Trips</label>
        <label><input type="checkbox" name="vacation" value="Volunteer"> Volunteer</label>
    </fieldset>
</form>

CSS:

label {
    display:flex;
    align-items: baseline;
}

input[type=checkbox] {
    margin-right: 8px;
}

I like this ...

HTML:

<input type="checkbox" name="vacation" value="Ski Trips"><label>very long label ...</label>

CSS:

input[type="checkbox"] { 
    position: absolute;
}
input[type="checkbox"] ~ label { 
    padding-left:1.4em;
    display:inline-block;
}
